Abstract. This study demonstrates the importance of the serviceability on e-commerce systems by giving some illustrations of e-commerce systems with low serviceability and the advantages of e-commerce systems with high serviceability. After reexamining a related work for bettering the serviceability of e-commerce systems and analyzing different e-commerce web sites with high serviceability, we suggest some guidelines to better the serviceability of e-commerce web sites. We use “ Likert Scale ” questionnaire technique to measure the efficiency of our attack. Using this attack, we find that the participants liked our attack and they helped us to better our attack by adding a status for our last guideline.

General Footings: Literature Reappraisals
Additional Key Wordss: E-commerce, Usability, Guidelines, Approaches, “ Likert Scale ” .
Rapid growing of e-commerce is truly impressive [ 1 ] . Nowadays ecommerce has become an indispensable concern platform for selling and buying merchandises among concern to concern, concern to consumers and besides consumers to consumers [ 2 ] . However, in the haste to supply online presence, many e-commerce web sites have been built rapidly, with small substructure and capablenesss needed to run such an e-business and such systems are designed with a focal point on concern ends.
Serviceability in footings of an E commercialism system is a step of the synergistic user experience associated with a graphical user interface ( GUI ) , such as a web site or a package application [ 3 ] . A good serviceability of an e-commerce system allows users to accomplish their ends expeditiously and efficaciously, it is user-friendly, its design is easy-to-learn, and is fulfilling and prosecuting to utilize [ 4 ] .
A cardinal challenge for e-commerce organisations is to understand client demands and to develop their Web presence and back-office operations consequently. As we all know with a user position, that the browse, seeking, and purchasing via online web catalogs can be really time-consuming, frustrating undertaking if the web site does n’t supply with the good serviceability. Therefore, any organisation with a Web site that is hard to utilize and interact with will project a hapless image on the Internet and weaken the organisation ‘s place. It is hence of import that an organisation be able to concentrate on the serviceability of their e-commerce offering, as perceived by their clients and in the context of the industry [ 5 ] . In simple words, on the Web, serviceability is a necessary status for endurance. If a web site is hard to utilize, people leave. If the home page fails to clearly province what a company offers and what users can make on the site, people leave. If users find troubles happening a merchandise or happening the necessary information, they leave and there are really less opportunities for them to return.
The web environment is the topographic point where clients have the power to take [ 2 ] . He or she who clicks the mouse gets to make up one’s mind everything. It is so easy to travel elsewhere ; as all the rivals in the universe are about a mouse chink off [ 2 ] . Ecommerce websites need to vie with each other in order to follow with the criterion of basic client ‘s outlook. Ecommerce concern demands to understand that they are viing with other shops that can easy be approachable by the clients who are doing an on-line purchase. Offering satisfactory and choice merchandise is non at all plenty. Good web site design is the most important portion in order to guarantee consumers holding a positive shopping experience [ 1 ] . Users will non blow their clip on something that is confounding, slow and do non fulfill their demands. If clients are non satisfied with the merchandise browse experience, they will non do a purchase from your web site. Most instances of e-commerce website failure is non because the user do non desire to purchase the merchandise, but it is because the user could non happen the merchandises they intent to purchase. Geting lost in internet can do users experience defeated and hard-pressed. They would non be considerate with a simple job such as difficult to happen the merchandises and the web site with bad pilotage. They will merely abandon the hapless serviceability web site as there are better web sites out at that place in the market. A new e-commerce web site is greatly depending on the good design and effectual user friendly pilotage. Lack of these standards will do user confuse, lost or frustrated and go forth for another site.A It is of import to happen the impact of usability badness issue in planing a web, every bit good as finding the most frequent and most terrible jobs to assist in prioritising [ 7 ] .
The advantages of systems with high serviceability extend beyond bettering a system ‘s design or its user interface ( UI ) and stop user productiveness ; its advantages include non merely the consumers but besides for the company. The benefits of useable systems include decreased preparation costs, limited user hazard, and enhanced public presentation [ 9 ] . Therefore, it becomes truly of import for developing an e-commerce web site that has good interface and serviceability design.
Businesss, holding late been involved in e-commerce may hold bantam experience and deficiency of cognition for planing their web site in order to pass on with users good. Poor e-commerce web site design will do loss in productiveness and income as been observed by [ 3 ] .A
As a consequence of one survey [ 7 ] , some serviceability issues were encountered often during proving the serviceability of e-commerce web sites, due to ill-defined classs or links and big lists of links or text. A Sing an illustration of a low serviceability, the Chinese online shopping providers proposed simplified payment and logistics systems, including Yahoo ‘s “ Easy Pay ” , Ruten ‘s “ Quick Payment Maker ” , PCHome On line ‘s 24-hour bringing and Books ‘ 24-hour pick-up at a shop on the following twenty-four hours. These systems aim to supply 24 hours services to fulfill user ‘s demands. However, clients can non digest redundant and complicated shopping flow. Therefore, a study made by A.T. Kearney ( 2001 ) proved that 82 % of users attempted to buy but gave up as a consequence of hapless serviceability and confounding flow [ 8 ] .A More illustrations can be considered to show hapless serviceability. There are as follows:
“ DPGraph web site ” sells package for math and natural philosophies visual image and it creates dynamic 2D, 3D, 4D, 5D, 6D, 7D and 8D graphs. In Figure1 we can see that this web site has a batch of unneeded images in bright colourss, that may thwart the consumers, and the background of the web site contains a batch of life with excessively bright colourss.
Sing one more illustration of an e-commerce web site with hapless serviceability is called “ Gates N Fences ” . The client sing this web site will see a batch of texts and images as in Figure2. The logo for the company on the web site does n’t fit with the background of the web interface. All these factors cut down the serviceability of a web site which causes a decrease in buying from the web site.
Successful e-commerce site purposes to accomplish the ends utilizing the serviceability factor as a key. Thos ends are: pulling user ‘s attending and facilitating pilotage. Another of import feature, related to serviceability, is easy and simple entree to the web site of the practical store [ 9 ] . As e-commerce web site is all about pulling and retaining client, it is important to vouch users holding a good experience throughout the whole procedure. Harmonizing to [ 4 ] , 80 per centum of extremely satisfied users will come back to purchase merchandises once more within 2 months and 90 per centum of them will urge to the others. However, 87 per centum of unsated users will ne’er come back without any ailments. They will merely travel off from the page if they encounter trouble in making their ends such as happening information and determination merchandises they wish to purchase.
A useable ecommerce system facilitates larning ; helps users retrieve what they have learned ; reduces the likeliness of mistakes ; enables them to be efficient ; and makes them satisfied with the system.
The benefits of useable engineering include:
Decreased preparation costs
Limited user hazard
Enhanced public presentation
Higher end-user efficiency may intend better gross revenues but apart from assisting users, it besides helps companies cut downing the development costs and shortens development rhythms. Users are the most beneficiary functions for higher serviceability systems, whether they are company employees utilizing an internally developed IT system, consumers utilizing commercial package or Internet-surfing shoppers looking to purchase from e-commerce sites [ 9 ] .
Usability-engineered sites offer visitants possible betterments in efficiency and productiveness. These footings mean an gratifying, instead than thwarting, experience, in which clients do n’t blow their clip seeking for ware or calculating out the procedure of doing a purchase ; an experience in which the shoppers feel confident and they are certain about non losing their credit-card and other personal information and guarantee that such information will stay secure ; an online shopping observation that leaves no uncertainty in the shopper ‘s head that the experience was superior to doing the purchase from a brick-and-mortar store. Shoppers besides get benefitted by non holding to take preparation, client support, consult and so do a purchase. When systems match user demands, client satisfaction improves automatically.
In a 1992 Gartner Group survey, serviceability methods raised user satisfaction evaluations for a system by 40 % . Better user satisfaction can take to better gross revenues for e-commerce sites and commercial package applications likewise. Users become defeated and leave the site if they do non happen appropriate consequences while sing e-commerce web sites. Useable sites enhance user experiences, doing them likely to remain on site longer and to return to the useable sites. Online shoppers spend most of their clip and money at sites with the best serviceability, harmonizing to Jakob Nielsen. Good pilotage and site design make it easier for users to happen what they are looking for and to purchase it. The possible for serviceability impacting the e-commerce underside line positively are rather favourable, harmonizing to Nielsen: “ It is common for usability attempts to ensue in a 100 per centum or more addition in traffic or gross revenues. ” Similar decisions can be drawn about the connexion between improved serviceability and better commercial package gross revenues [ 9 ] .
E-commerce web site contains other elements that play of import function in heightening serviceability. These elements are ;
One survey [ 10 ] illustrates that the undermentioned heuristics help bettering an e-commerce web site. These heuristics are combination of ratings of e-commerce sites done by different publications.
The matching of services, merchandises and advertisement content with single consumers is called personalization.
An of import thought has to be taken into consideration here ; User profile which is embedded in the personalization procedure. User profile is the demands, penchants, behaviors and demographic traits of a peculiar client.
Profiles can be generated in several ways:
Solicit information straight from the user
Detect what people are making online
Build from old purchase forms
Perform selling research
There are different fiting methods which can be applied ; one of the most of import ways of matching is collaborative filtering. Collaborative filtering is a personalization method that uses client informations to foretell, based on expressions derived from behavioral scientific disciplines, what other merchandises or services a client may bask ; anticipations can be extended to other clients with similar profiles.
It is of import to happen out how e-commerce web sites can show information to a user in a manner such that, it promotes a comfy, effectual and efficient interaction between the user and the web site. The expression and feel of an e-commerce web site should be based on user demands. Page format and navigation characteristics should be as intuitive and easy understood by clients as possible [ 10 ] . A level hierarchy of information is of import for a successful web site design. The hierarchy of information should be evident at a glimpse so that the information available on a page is easy understood by users [ 10 ] . User should easy acknowledge any choice points or pilotage controls.
Shoping Cart is a package application that runs on the web waiter. It allows clients to seek for specific merchandises and add them to the shopping cart or shopping basket and topographic point an order for it. Shoping cart usually includes:
A database that shops information such as merchandise inside informations, client informations, order information, etc.
A shopfront that displays this information to shop visitants ( e.g. merchandise item pages, hunt pages, check-out procedure pages, etc. )
An disposal country that allows the shop decision maker, to pull off the shop.
The Shopping cart application creates pages in existent clip upon client ‘s hunt on a specific merchandise. It means that the pages about the merchandises do non be in the system until the client petition for that and these pages are rather dynamic.
Electronic payment systems can be grouped into three wide categories:
Traditional money minutess
Recognition or debit payments
Such payment systems have a figure of demands such as security, acceptableness, convenience, cost, namelessness, control, traceability and control of encoding methods [ 13 ] . To the above classs, the go-betweens can be added. There are a few companies online such as Credit, Google check-out procedure, PayPal who will ease client payments, and frequently protect clients from, or supply alleviation from fraud.
The synergistic rhythm between a user and a web site is non finished until the website responds to a bid entered by the user [ 10 ] . Harmonizing to Norman ( 1994 ) , “ feedback directing back to the user information about what action has really been done, what consequence has been accomplished-is a well known construct in the scientific discipline of control and information theory [ 12 ] . Web site feedback frequently consists of a alteration in the ocular or verbal information presented to the user. Simple illustrations include foregrounding a choice made by the user or make fulling a field on a signifier based on a user ‘s choice from a pull down list. Another illustration is to corroborate that a merchandise has successfully been added to an electronic shopping cart. Completed orders should be acknowledged rapidly. This may be done with an recognition or fulfillment page. The sum of clip it takes for a web site to react by bring forthing and downloading a web page. However, this is considered as a beginning of defeat for many e-commerce users. Users are non tolerant and are speedy in bring forthing misconstruing sing such events. Receiving a clean page, or “ a long delay clip ” to have an recognition, may be interpreted as “ there must be something incorrect with the order. ” If bring forthing an recognition may take longer than what may be moderately expected by the user, so the design should include intermediate feedback characteristic to the user bespeaking the advancement being made towards confession or fulfilment.
[ 10 ] After reading several documents and surveies done by different writers, we can reason that serviceability plays an of import portion in e-commerce systems. We can be after our web site to hold the highest sum of serviceability that helps user doing a purchase or utilizing the web site by adding several aims to the design. They are as follows:
The first aim of this survey is to look into and analyze the serviceability of the e-commerce web sites from design point of position. For this facet, relevant variables have been identified ; Technical variables which have been examined consist of Online GUI Design and some sub factors. The sub factors lending to the website serviceability identified in this survey are as follows:
aˆ? GUI Design: Page Design, Personalization, Information Presentation, enrollment & A ; look into out, Shoping Cart and payment system, Feedback, Speed, Accuracy, Responsiveness and Understandability.
Harmonizing to this aim, the chief end is to place the influence of the discussed variables on the serviceability of web sites. Several relevent study consequences indicated that a user friendly design and easy-to-use interface would increase online user ‘s satisfaction with the web site significantly. Harmonizing to statistical analysis that has been done in this survey, concludes that the personalization and page design have great influence on website serviceability. Users are concerned with some of the variables a bit more than the other 1s i.e. privateness, but about all of the variables mentioned and discussed have great significance in user ‘s determination to revisit the site.
To accomplish this aim, the survey intended to happen out the most of import factors from users point of position. By acknowledging the degree of importance of different factors, we can propose the interior decorators and web site developers to use these factors more efficaciously which will assist in heightening the serviceability of the web site they are developing. If the interior decorator becomes cognizant of what is of import for the users, so he or she can foreground that specific characteristic to fulfill the user and warrant users revisit.
After analysing assorted e-commerce web sites and detecting the difference, we suggest following 12 guidelines to better the serviceability of any e-commerce web site. The order is non of import, and these guidelines are:
Identify users with their e-mail reference
Always try and use an e-mail reference to place users, instead than a username. This is because e-mail references are easier to retrieve and are more standard compared to usernames. That means e-commerce consumers do non necessitate to worry about particular characters while making the user names and holding them forgotten at a ulterior phase. Email references are ever alone, so consumers can avoid the job of another user holding already taken the username chosen by them.
Put users ‘ heads at easiness
Many consumers are still non 100 % comfy while doing a purchase online and sharing their personal information. They might be concerned about giving out their recognition card figure, or about non having the points they have paid for. It hence becomes an of import measure that you allay these concerns and set user ‘s heads at easiness. Show them the warrant that their minutess are taking topographic point in a secure environment. Show them how their minutess are encrypted and therefore protected against cyber menaces. Try and believe about the concerns consumers might hold at each measure of the telling procedure, and seek to turn to them. For illustration, Tesco6 shows a privateness notice to their clients at the payment phase of the telling procedure explicating about client ‘s safe minutess and protected recognition card information adverting that it ‘s wholly safe to shop at Tesco.com.
Keep security badges, trust certifications and an updated SSL on the web site
It is of import to vouch the shoppers that they are purchasing from a secure shop and you make an attempt to protect their privateness, personal information, charging information and any other private information shared during a dealing. Many e-commerce merchandisers use security badges and trust certifications from topographic points like Hacker Safe, VeriSign or STruste to demo shoppers that they are purchasing from a secure shop or trade name. It is besides necessary to hold an updated SSL certification so the appropriate “ lock icon ” appears in the lower right corner of shopper ‘s browsers when they fill out unafraid subdivision of your web site while doing a purchase.
Allow shoppers to polish merchandise consequences by colour, form, size etc and let them to unclutter those polishs anytime
A client must be able to happen the merchandises they are looking for rapidly and easy. Another great manner showing personalization of the web site is to maintain points within the range of clients by implementing polish characteristics that allow visitants to screen merchandises by colour, form, size, trade name and more. Many e-commerce sites do non hold the capableness to utilize polish characteristics, others are more flexible in their designs and let such customizations. Such customizations provide flexibleness with adding a merchandise to the cart with certain standards and aid clients salvaging their clip.
Other factors impacting personalization of an e-commerce web site can be considered as below:
Make certain contact information for the supplier ‘s client support system is seeable by the clients
While utilizing your web site clients may necessitate to take aid from client support to decide their questions. Supply a aid line that can reply client ‘s questions. Ensure that the client support figure is seeable on each and every page and besides do certain that systematically it is placed at the same location instead than puting it in different location on every page.
Keep the site hunt map above the crease and in apparent position so shoppers can question the catalog anytime
Make sure that the hunt box is available and is seeable by clients easy so that they can question the catalog at anytime during their visit to the web site.
Allow shoppers to demo a designated figure of points per page anytime with a “ show per page ” kind option
Apart from sing merchandise polishs options, you may desire to include a characteristic that facilitates the clients to screen and polish the merchandise list displayed within classs. Display screening may include a grid layout, list layout or loanblend ( uses a combination of both ) . By giving them these screening options, you are basically giving shoppers different ways to see lists of points once they are displayed on a consequences page.
Make certain shoppers can easy entree their cart contents and that it can easy be modified or adjusted
Ensure that the shopper ‘s cart is easy approachable by them on each and every page. This will increase the transitions and aid clients in happening what they are looking for and makes it truly easy for them to look into out easy. Many e-commerce sites have a list of merchandises on separate pages and add to haul option is on a separate page. This will do clients travel back and forth every clip they want to add a merchandise to the cart, which may ensue in losing clients. Apart from doing the cart accessible, you should ever let clients to redact the contents of the cart any clip during the cheque out stage of their purchase. Shoppers may ever wish to replace contents that have been added to the cart already with the other points. This helps acquiring less derelict cart and more orders.
Show the monetary value of the point, sum saved and any applicable transportation or revenue enhancements as early in the procedure as possible
Do non surprise clients at the terminal of their purchase. Always show the accurate monetary values to the clients at each and every phase of the purchase. Keeping charges hidden and surprising clients by bear downing their recognition cards more than they expect it to be charged, will non assist in increasing gross revenues. Rather it will ensue in loss of clients.
Show stock and handiness of merchandises every bit early as possible within the check-out procedure and order procedure
In add-on to antecedently mentioned points such as demoing accurate order sums and transporting sums, it is besides a good thought to do merchandise stock list seeable to the client. By doing the merchandise stock list available to the clients before they add a merchandise to the cart, you are efficaciously doing your web site useable. If the stock list appears after the point has been added, there are opportunities for you to acquire more derelict carts and more calls into your client service line asking about merchandise handiness. In add-on to demoing them inaccessibility of the merchandise, show them when the merchandise is expected to get on the shop itself. That will assist acquiring the client revisiting the shop, do more purchases and less calls to your client service line.
Offer a assortment of payment and transportation options so shoppers can pick the 1 they have an history with or most frequently use
It would non be an appropriate thought to free a client merely because non supplying them with suited options for transporting or payment methods. Allow clients to choose suited transportation options such as UPS, FedEx and many more. In add-on to that allow clients to do a payment utilizing legion payment methods such as Credit, PayPal, Google check-out procedure and many more. This will assist clients happening appropriate lucifer and increase convenience for them.
Allow shoppers to add points to their cart before doing them registry for an history
Leting invitees to add points first and give them the option to register after the order.
Many e-commerce sites do non let clients to add points to the shopping cart until they have registered for a site history. This means the clients have to take an excess measure in purchasing procedure and could coerce them to go forth the site before they buy. It is of import to let invitees or window shoppers to add points to their cart and check-out procedure earlier registering as a client. It does n’t do sense to roll up user information when you know that purchasers will come in in much of the same information upon telling. By giving them flexibleness to shop the merchandises and add them to the cart without registering aid clients save their clip.
Tell users where they are and where they are traveling
It can be thwarting for users when they are seeking to purchase something online and they do non cognize how many more stairss are required before doing the concluding purchase. Most of the users leave the site without doing a purchase if the purchase procedure is excessively complicated and they do non cognize how long it would take for them to finish their purchase. This is why it becomes of import to allow users cognize where they are in the ordination procedure, and how far they have to travel. For illustration, Dixons2 shows the current ordering measure, and the stairss still to travel.
Use merchandise page transcript that answers shoppers inquiries about merchandises they may be interested in purchasing
Page and merchandise transcript ( text headers and descriptions ) is an of import facet of serviceability for both shoppers and hunt engines. The headlines for merchandise pages, messages, buttons and calls to action an e-commerce web site chooses can all act upon on whether client bargains, adds something to a wish list, chinks through, subscribes, or whether they move along to another site. Keeping the merchandise page transcript or reappraisal for that merchandise, helps client doing a purchase. For ex: A client shoping a merchandise and reading the description finds that the reappraisals for those peculiar merchandises are non good. They will non travel in front and do a purchase. This besides helps deriving client ‘s trust for your web site. Consumers trust other consumers better than your web site. Therefore, it helps them taking a determination towards doing a purchase or non. Basically, the headlines and other page transcript should be the first thing the clients see upon set downing on a specific subdivision. Keeping the headlines simple and direct, it is of import that clients will be able to finish a purchase or happen an point they seek from that page. It is of import to utilize keywords that describe the point on that page within headers and elsewhere within the transcript.
Use larger fount for “ add to haul ” button that is easy seeable and see dictions such as “ proceed to check-out procedure ”
The chosen “ add to haul ” buttons can do or interrupt a shop, particularly for new e-commerce sites. If the check-out procedure buttons are non easy seen by the shoppers so they do non go on with the staying stairss. The e-commerce web site will so hold a hard clip change overing many of its shoppers to purchasers. Small alterations in colour, fount, size and appropriate use of give voicing have been proven right to increase gross revenues, transitions ; raise mean order sums and helps direct shoppers towards the following measure in the purchasing procedure. The web site should maintain the check-out procedure and cart buttons within the client ‘s range on each merchandise page.
After puting an point to the cart, allow clients compare the monetary value with other web sites for the same merchandise with merely one chink
Once client selects a merchandise from your web site, add a mechanism to your web site that allows clients to see the same merchandise with the monetary value difference. Guarantee them that the merchandise being purchased from your web site is the lowest monetary value compared to other e-commerce sites. For ex: A client adding an point to the cart finds a nexus someplace near to the merchandise description, Which allows them to compare the monetary value with different web sites. By snaping that nexus, client gets navigated to the new window, where the same merchandise is shown with different monetary value naming with different service suppliers. This saves client ‘s clip that the clients do non necessitate to open different web sites and look into out the monetary values for the same merchandise and compare them.
Besides this thought helps deriving client ‘s trust by vouching them that your web site offers them the merchandise with best monetary value than other web sites do.
Show related merchandises and cross sell before the check-out procedure procedure and after points have been added to the cart
Grouping merchandises, demoing related points and cross merchandising is of import for clients and helps take downing shopping cart forsaking rates. Many e-commerce shops prefer to demo related points on each and every page a client reviews a merchandise instead than demoing related points for the merchandise that has been added to the cart. Make the purchase procedure easy for shoppers by demoing them related merchandises for the points that they have added to their cart. That helps shoppers happening the related merchandises, fiting their demands and make non take them back to the index page or do it hard to redact the cart contents. A batch of carts get abandoned when a client finds that they can non easy redact the cart or that they get redirected back to the index page once they add an point to the cart.
Have users confirm their order before they make a purchase, so supply verification
Try to remain every bit transparent as possible. Buyers would ever wish their order to be confirmed at least one time before their recognition card is charged. The last phase of the telling procedure should ever inquire the user to corroborate their order. Users should be able to see a elaborate sum-up of their order, including how much it will be and where it will be delivered to. They should so either be able to call off or go on with the order. It is likely the best thought non to copy something like Amazon ‘s “ 1-click ” telling system7, because this allows orders to be placed without look intoing and corroborating of import inside informations, such as the bringing reference and bringing costs.
Confirmation should be provided for orders placed, so that users know whether their order was successful or non. This should include following information:
The expected bringing day of the month
The order figure
The trailing figure
How to track the order online ( if this is possible )
Addition of a characteristic to the e-commerce websites utilizing smart phone applications, that can pull out client ‘s information and recognition card information ( For illustration, First and last name, charging reference, recognition card information ) by scanning the recognition card and allow client do a purchase rapidly
Nowadays, we find figure of applications working on different platforms utilizing smart phones such as scanning applications that scans the barcode of the merchandise and gathers all the merchandise relevant information ( merchandise name, merchandise figure and merchandise version etc ) . We likewise could plan an application that scans client ‘s recognition card and collects recognition card information every bit good as client ‘s private information. Customer so can utilize this information to do a purchase with the aid of their smart phones. This avoids clients come ining such information to the merchandise purchase page and salvage their clip.
Finally, Test different combinations of best patterns to see which 1s produce the best consequences for your e-commerce web site.
We used a questionnaire that includes some inquiries to mensurate the efficiency of our attack from the user ‘s point of position. The questionnaire uses “ Likert Scale ” get downing from strongly disagrees, which equals to one, to strongly hold, which equals to five.
About 12 participants, 8 females and 5 males, in age between 20 and 30 old ages participated to reply our questionnaire. The participants are educated and have an experience in online shopping. The participants were honorable and did their best in replying the inquiries. They were given 12 inquiries to reply.
In our attack, we suggest twelve guidelines to better the serviceability of any e-commerce web site. Each inquiry in our questionnaire evaluates the efficiency of each guideline. For each inquiry, the participants can take one of the “ Likert Scale ” grades, get downing from strongly disagree ( equal 1 ) to strongly hold ( equal5 ) . See Appendix A.
After each participant replying the questionnaire, we took the norm of the grading for each inquiry and summarized in the undermentioned tabular array:
From the old tabular array we can see that all the participants like our guidelines to better the serviceability of e-commerce web sites, and all the evaluations were above norm, which equals to three, except the last guideline, which suggests to take the needed information from the recognition card, some of them disagreed this suggestion because they think it will non be to the full secured. On the other manus, some of the participants agreed with the last guideline if it is provided with a extremely secure system that protects their information given to the application. An of import note can be made for attack 11, that all users strongly agreed to it ( i.e. the overall evaluation is 5 out of 5 ) and mentioned that users must be confirmed with the arrangement of their order and its position.
Reasoning to this tabular array we found a histogram of norm that can assist you analyse the importance of our attacks and client ‘s understanding on that in a chart position.
Usability plays an of import function in pulling clients to the web sites. After analysing the consequences of the questionnaire, we conclude that the combination of our guideline will ensue in high serviceability e-commerce web site that satisfy the user demands and we can add an excess status for the last usher, which is to supply a extremely secure system that protects user ‘s information. In decision, we can state that there is no chiseled comprehensive set of serviceability properties. We can add as many properties as we want to guarantee client ‘s satisfaction and do it extremely useable by the clients. A extremely useable web site is one which provides an intuitive interaction to the clients. A hapless design can stop in loss of clients and affect the trade name of the company. On the other terminal, a web site with high serviceability can do in more loyal clients and more net income.
Therefore, following serviceability guidelines and transporting the serviceability proving with existent users for the designed web site, we guarantee that the ensuing web site will be extremely useable and accepted by clients.
