What is an Interactive System?
In the present world due to rapid growth of technology people can order things or purchase home supplies while they are still home seated. Many Companies which have adapted the online business services have been on the verge of the market as they are now offering home delivery. For this urge and need of products the users or consumers have found themselves downloading the mobile application for a specific company selling online or browsing information regarding the online selling websites using their browsers. Though there are so many companies adapting the online selling, thus this as made many consumers to be so selective of the information provided in the application or in the website. When consumers realize that the information they are seeking is not clear then the user will evade that website and search for another selling site that meet his or her needs. This scenario of consumers being selective has made many people to be eager when interacting with the already posted products by checking if they are effective, how safe they are and if they satisfy their requirements with the duration needed. We need to evaluate the Jumia express selling website (ExperienceUX, 2018). The first question in this proposal is asking what is an interactive system? Interactive system can be defined in many ways which depends on the discussion area but in this concept the topic of discussion is the usability testing (point, 2018). The point of reference is the Information security in a applications used in smartphones or a website that can be applied on browsers on machines or phones which may allow user to perform functions and operations such as the E-commerce, selling games online, Electronic devices, E-book and many others in all range of products existing in the world (meich, 2017). According to Nielsen Jacob there are considerations and requirements that need to be analysed and designed when we are determining how capable usability can if performed (Johnson, 2018). The following content below explains all the considerations or principles to guide in doing an evaluation of the usability testing of Jumia Express Selling Website (NIELSEN, 2013). Some of the questions to ask when doing evaluation are us follows (Jakob, 1999).
- What is the consistency of the information, content and the design of the Jumia Express Selling Website?
- Does Jumia Express Selling Website have a look and feel in its Graphical User Interface?
- Is it easy while navigating the Jumia website webpages?
- Does Jumia website show some clarity and visibility in the mobile application or in the website(Nielsen, 2015)?
- Is there in any way Jumia website interactive system matches with the real world?
- Does Jumia website shows have support such as help and documentation assistance to the users of Jumia?
- Is it possible for Jumia Website to recognize, diagnose and recover errors if they occur when dealing and interacting with the application?
- Is the Jumia websites supportive in terms freedom and control of the user?
This report aims at giving a detailed explanation of the human interaction usability test of Jumia Express Selling Website. Jumia Express is an online selling website that sells its good in most Africa countries and doing very well in Kenya. Jumia has been known to deal with all types of goods where they can sell at wholesales, retails and even specific products and doing home delivery to your home and you pay after the good or service has been delivered to you. The concept is like that of Amazon just that in this one it still has not yet gone international to other continents in Africa. In Jumia Express consumers of goods can view goods on their websites, adding goods they want to shopping cart and placing an order where they will follow up with immediately they receive an order. This report is aimed at giving a detailed analysis where we use a questionnaire in investigation and evaluating the usability test of Jumia Express (JannaDupree, 2014). Lastly after the evaluation is done we will have to explain all the findings analysed from the investigations or the answers from the questionnaires and thus recommending on what need to be done by Jumia Express depending on the result from findings (Garyperlman, 2018).
Jumia Express and its Operations
Jumia Express of late has been known to be dominating the sales of products online in Central, East and West Africa where it has been engaging itself in selling goods at wholesale and retail prices which are much convenient than buying from normal shops (Rouse, 2017). Jumia Express is a company that is selling about 2 million products in a day which ranges from food, flight, travels, houses, party, men’s fashion, women’s fashion, TVs audio and cameras, computing and beauty (Jumia, 2018). Jumia is termed as one of the biggest online mall that has many warehouses in respective countries where it sells its products to countries like Algeria, Cameroon, Ivory Coast, Egypt, Ghana, Morocco, Nigeria, Rwanda, Senegal, Tanzania, Tunisia and Uganda. To interact closely with the customers Jumia Express has been for a good website that a graphical user interface has a good look and feel making it easy when one want to search for products as it is easy when interacting with the website or the mobile application and lastly the navigation across all the webpages is very easy in Jumia Express (Yitmen, 2013). The products at Jumia are classified depending on the category they belong just like the way products in supermarkets are physically arranged (niloda, 2014). This website growth and update each and every day as it allows one view products anywhere with regard that you have some internet (Department, 2018). In Jumia Express one can view the good may it be a phone, place it in the shopping cart if you are willing to buy and order where they will get back to you and asks the location you discuss on the pay on delivery (www.nngroup.com, 2014). The explanation below is the Jumia Express use case that shows how one interact with the system on the mobile application and the website on normal browsers after selecting the products.
In the above diagram in Jumia Express customers interacts with the websites in so many ways where they purchase products online and if a good is delivered to the consumer and paid immediately we term this as a successful transaction (Lucidchart, 2017). One have to open the Jumia express and understands what happens from the moment you view the homepage and navigates through all the other pages all through the coursework of doing so. This use case is good start explaining all the functional and non-functional requirements of Jumia Express stating how usability testing can be enhanced when users interacts with the webpages. The test was based on how easy it easy to interact with the website, the consistency of graphical user Interface of Jumia Express, the look and feel and much more the clarity and how visible it is when interacting with the Jumia Website (UserLytics, 2017).
Usability Testing Principles
The evaluation test is based on application of cases that helps to guide consumers to participate in the usage of Jumia Express where we will analyse all the functionalities and additional features for proposed system when doing usability testing (ATSDR, 2016). In this proposal of usability testing a total of 5 people who have never interacted with Jumia Express there before where each and every participant is given 15 mins when being observed by the researcher while interacting with the Jumia Express website or Mobile Application (ufl, 2018). The major areas that were targeted by the researcher were the way the participants created their account by signing up then they login after being verified, starts viewing the products by selecting their choice, adding it to the shopping cart and lastly making that specific order. This methodology has been explained by use of cases that has explained all tasks to be completed as per the specific case (APCRC, 2017).
In this case the user pays attention to what the homepage of Jumia Express entails where one checks all what is available and start navigates through the products offered depending classified categories and the content they portray in terms of description and price and how convenient it is in terms of delivery and time (www.jumia.co.ke, 2018).
In this case the user is tested on how he can navigate across the Jumia Website where he have to interact with concepts like phone & tablets, Supermarket, Women’s Fashion, Men’s Fashion, Beauty, Jumia Global, Food, Travel, Flight, Computing, Fashion accessories among many other categories and webpages. In this case it is performed for the issue of navigating through the website using all the categories in all ways.
In case three the participants are required to select three item on phones and tablets and computing where they view the chosen products, adds them to the shopping cart and make an order
In this case much of emphasis is placed on how many webpages the participant have visited on the Jumia Express. All users had visited more than 10 webpages where we concentrated on how the webpages were visible and clear to them, how consistent the context of the webpage is to the participants. In this scenario the participants were required to record all the webpages they had visited clearly indicating all the content they have and how they are represented in the website.
The case five is known in that we will test the user requirement by asking them to create a gift card for their friends (recipient). The participant had to choose a design of the gift card that they were to send to the recipient giving all the information’s about the recipient and pay using Mpesa.
Test Cases for Usability Evaluation
As explained from all the above cases from one to five the 5 participants navigated through the Jumia Express website were able to learn a lot and the knowledge gained with a lot of experience for first time interaction with Jumia Express. The focuses on all the cases from 1 to 5 was based on checking the analysis of the usability of the Jumia express website and its mobile application checking how the graphical user interface is consistent, how the content in the webpages is relevant to the participant and the way or how easy it is when navigating through the Jumia Express Websites. As discussed above all cases have explained all the steps from the moment the participant logins in the Jumia Website to ordering the good.
After performing all the tasks in all five cases the users were required to answer the already prepared questionnaire which entailed all of what they had experienced in the website. The aim for the questionnaire was making the participant understand the general view of Jumia Express Website explaining on what they learnt in the processes as they navigated across Jumia Express Website (Explorable, 2017). The rating of the interaction was supposed to be given out of five and clearly indicates it was good or bad experience.
The methods that were applied in evaluating were good and made the users to feel the features even when observing. The questionnaire was used to help us to know the way the user feels about Jumia express something that was very easy but it was hard to perform when observing the executions of the scenarios above. The methods were considered to be so effective in that they gave results that were appropriate for the research.
Based on the already discussed cases then there are a number of concepts that will need to looked upon as realized from the questionnaire (juben, 2013). All the participants performed the given tasks alternatively following the indicated instructions in the same way for all for the purpose of achieving the major objectives.
The aim of case one was testing the navigation through the Jumia Express webpages where we had to sign up and login to the website all the app and start viewing all what the site entails in the classified and categories as indicated in the site. The first case was performed easily as many did not experience any problems when navigating where by about 4 out of the 5 stated that this case task was not necessary as it was direct and straight to the point and termed it as time wastage and this resulted to them saying that they need to be taken to the major tasks directly. The figure below explains the homepage of Jumia Express Website.
Findings and Recommendations
As we all know we had five participants and not all of them were satisfied to the way the hompage of Jumia Express was designed concluding that the design is so detailed and not appealing to the eye as it was much of images rather than the actual content. The table shown below explains the way the four features in the design were observed and explained.

The idea behind case two is checking how easy it was navigating across the JumiaExpress Website
The idea here is to test the navigation feature. To check if it is easy or hard to navigate across the Jumia Express Website and this will be also concentrating much more on the Nielsen statements on the considerations such as if the content describing the images of the products matches with the real products and how this is relevant to them. The other idea in case two is how the consistency of the design will be favoring the participants (vescoir, 2011). In this case we were abe to navigate through the supermarket that is the toiletries and the dishwashing webpages respectively. when the partcipants were questioned on the website design they all said that the design is appealing and has a look and feel feature as it was easy to navigate through the classified products. The figure below explains more on the visited pages .
Four out of the five participants said that the navigation from one page to the next was very easy, appealing and much satisfying their expectations.
The maid idea was to check how it easy it was searching the product and selecting it in the classified categories. Just like navigation 4 out of 5 declared that they were able add items in the shopping cart comfortably with no help. The following shows the procedure of placing the three items that were to be selected from, both the phones & tablets and the Computing in Jumia Express website.
The idea here is to test how clear and relevant the information is when we navigate through all the pages where we analyse all the additional features that help us in defining the products we need (Microsoft, 2015). The procedure below shows a more explanation of how the additional features may be applied to show relevancy and clarity.Assuming we want to buy a phone which is Samsung model.
There are other additional features provide by Jumia to help in being specific. This are things like setting the price, sort by etc. In this case we want to set the price of kshs 10,000 to 30000
Conclusion
This sort by feature is done by searching the below.
- Most popular
- New in
- Lowest Price
- Best rating
- Highest price
The idea here in this case is creation of gift card for a friend. Only three out of the five were able to do this process of sending a gift to a friend using the Mpesa as the mode of payment.
About 85% from the 5 cases completed all task successfully without problems which corresponds to 4 out the five participants. The idea above helped in rating Jumia where threating from the all tasks gave Jumia Express a rating of 4/5. The graph below illustrates how it was.
As discussed and recorded from above then it is wise to say the rating of usability is very high clearly showing all factors of HCI such as the consistent, visibility, clarity and ease of navigations as explained by the participants from the questionnaire (JannaDupree, 2014).
The design and the alignment of Jumia Express was recorded to be 4/5. Though there was one who complained that the website were much picture oriented and hence becoming hard hard to interprete the images (Microsoft, 2000). She proposed Jumia Express to label most of its images used with just a single name so that if one clicks on it then it will take him or her to the detailed description of the image (nielsen, 2015).
From the graph almost all of them were able to navigate across all pages in Jumia Website. Most recording clearly shown that it was easy to interact with the system where there wery few challenges. The recording resulted to about 90% all agreeing that the website was clear and visible and easy to interact with.
The content was highly recommended to be very necessary and much more very straight to the point when understanding. The other additional features like the setting the price range and sort by helped in aligning and satisfying the user requirements as it made it easy locating the products (istqbexamcertification.com, 2012).
I would recommend on the alignment of the homepage in that the pages are well aligned where we can apply the use of features such as the slide sorters. The live chart should also be in a place where it can be seen and the price currency of goods should be the international one like dollars.
Conclusions
As discussed from above, the test has been done in testing the quality of the website. For the website or the system to be of good quality then there are some standards that will need to be visible to the viewers or users that shows all the content clearly ,easy when navigating across the pages and much easy to locate the selected products the best way possible in an efficient manner. We have also noted the additional features like sort by, Filter, Price range set, search engine and many others have helped in saving time to locate a product. The procedure followed from case one to case five have clearly indicated that it is easy to understand a given site even if we are new from such websites (Microsoft, 2010).
