Use case Diagram
This provides a brief summary of the details of the system and the users and how the two are interacting together. This requires a set of some more specialized connectors and the symbols. Of importance is that the use case diagram represents the scenarios in which the system application is interacting with the people and the whole organization behaviour at a large. The scope and goals are also well represented here ( Seidl, Scholz, Huemer and Kappel,2015).
Figure 1 Use Case Diagram
Characterizing necessities to set up details of the information system is the initial phase in the advancement of an implanted framework. Be that as it may, as a rule, insufficient consideration is taken in building up adjust prerequisites in advance. This causes issues when ambiguities in prerequisites surface later in the existence cycle, and additional time and cash is spent in settling these ambiguities. Subsequently, it is vital that prerequisites are set up efficiently to guarantee their exactness and culmination, yet this isn't generally a simple errand. This trouble in building up great prerequisites frequently makes it a greater amount of a workmanship than a science. The advancement of tried and true inserted frameworks requires considerably more confused prerequisites since the implanted framework communicates together with outside world and the product itself. Through this, setting up of the great prerequisites is of much importance when it comes to the installation of the considerate noteworthy frameworks (Gezelius, 2017).
Benefits of mobile application
The use of a mobile phone in an organization comes along with a lot of benefits to the realization of the business objectives and the stated goals. The fact that the usage comes with advantages, a sample of interest is the portability and the wireless connectivity factors. These allows all the users to communicate at all instance, this is facilitated by the intense competition among the mobile phones manufacturers.
The business is also benefiting from the use of a mobile application through then awareness in that the logo used in the mobile application create an awareness to the users and this promotes the brand of the business hence promoting it (Cornelia and Repanovici., 2017 ) Apart from this, the mobile application will be allowing the customers feedback hence facilitating the customer support feature. The fact that the application is cost effective, all the businesses will be able to meet the requirements within the budget limit. The mobile phones have come along with many features which as affected the native websites. The design of an application has promoted the companies in that there is faster access at any given place without the need for the installation of the huge hardware devices. Again the mobile application has promoted the companies by providing the faster time for loading of the page apart from the optimized user interfaces which adds the functionalities of the mobile applications. Generally, an increased number of people are seen using the mobile phones to access important information compared to the access using the websites.
The perception of the business professionals on the use of the mobile phones application in the workplace is of importance when it comes to the design of the system design. To clearly have an understanding of this, a research survey need to be conducted. There was a need to conduct an online survey in the social media groups to reach all the business people and again during the business meetings. The main target of the survey was the owners of the mobile smartphones. Since it was a direct survey majority of the respondents were able to tell that the applications will be of importance since their phones will be providing all the services at once and this appeared to be simple.
Abstract standards assume that people take after the conduct of individuals that are imperative to them, regardless of whether the individual does not feel that the results of following that conduct are especially ideal. Because of social weights to embrace the new innovation, a person's view of handiness coordinated to that innovation would fortify ( Khan, 2015). Willfulness is characterized as the level of which an individual trust they have the opportunity to receive another innovation, in other words; is the reception of this new innovation obligatory or non-compulsory. The level of intentionality of receiving another innovation will impact abstract standards, however have no immediate effect on PU. At long last, picture alludes to how helpful an innovation is in lifting a person's social position inside the gathering, if another innovation can enormously enhance a person's social standing then the PU of the innovation will increment.
Work Breakdown Structure
This defines the user requirements for the accomplishment of a project. The project tools are organized together in a series of multiple levels which are displayed in a graphical manner, (Harrison, Frederick, and Dennis , 2017)
Figure 2: Work Break Down Structure
From the above work break down structure, the system development of the android application has been considered in different stages, the initial stage of planning of the design of the system followed by the gatherings of the requirements. All the systems documents are brought together into one platform where the system designer can easily reach. After the collection of the requirements files. The designer goes ahead to design the user interface. The interface should be easily understood by the user hence attracting for more usage. Once the designer has a layout of the application both n mind and in a written document, the initial process of coding begins. At this stage, the designer will be dealing with the application code in java language while on the other side, the connection to the database since the app is required to be communicating with the online website ( Bartel et al., 2015).
Once the overall coding has been accomplished, the mobile application is now subjected to the testing and the end final deployment. At the testing stage, the application is carried through a series of test including the unit test, integration test, acceptance test and the system test. In the unit test, a system is tested as a small module and is ensured that it fits its overall functionality. Each of the module is tested individually till it is approved to meet its required objective. Once this is done, an integration test is done on the combined units. This is to ensure that the units can be working in an associative manner with other units ( Buede and Miller 2016). Through the integration test, a user will be able to understand the failures that could be arising in case the whole units are brought up together as an overall system.
The overall system is now tested to acquire the actual functionality. This ensures that the stated objectives are set to meet the solution to the problem in question. Finally, user acceptance test is carried out to ascertain the desired qualities.
In this study, perceptions of business professionals towards use of mobile phone in the workplace as well as at the business meeting settings were analyzed. Findings of the study indicate the fact that, mobile phone usage at work is positively welcomed in general by most of the professionals. Professionals especially appreciate “the flexibility” and “the ability of doing a better job” through accessing corporate emails and other business apps outside official working hours and they strongly believe that “mobile phone usage at work is necessary”. However, they slightly believe that their colleagues inappropriately use mobile phone at workplace. The use of mobile phone in formal meetings is questioned as well. To some extent, it is acceptable for professionals to bring phone to the meeting, excusing oneself to take a call and checking time. However, checking a social media account, taking a call without excuse and browsing Internet due to boredom are regarded as inappropriate in formal business meetings.
