Chapter I – Introduction

Service desk is the communication centre which provides single points of contact (SPOC) between staff and company, business partner along with employees. The main purpose of service desk is ensured that staff receives proper help within a time. It is designed for handling both services request and incidents which is considered as an event to improve service quality. This report is premised on developing a mobile application for Qatar Petroleum Company so that they can provide better quality services with the help of service desk systems. This mobile application is developed for improving staff service quality.

1.1 Project Aims

This mobile application is developed to solve problems of all Qatar Petroleum’s staffs within limited period of time. This app saves time for raising queries or requests at office because there is lots of work which are performed outside of this office. In this case, employee can use this mobile app to file a complaint with the emphasis on a multi-dimensional collaboration.

1.2 Project Objectives

Qatar Petroleum Company wants to develop their service desk so that “The Mobile Application Enhanced Service Desk System (SDS)” project to solve problems of all employees. On that note, identified problems are transferred for mobile verification after desktop verification and all problems trying to solve faster and on time. In order to achieve this aim of this project, there are listed following objects-

  1. Establishing measurable requirements of all stakeholders in this software.
  2. Developing this mobile application with the specified functions in a mobile version.
  3. Evaluating performance of this mobile application in real life scenario for future improvement procedure.

1.3 Minimum Requirements

This mobile application is developed to solve employee problems. In this case, this mobile application must be incorporated user friendly and multilingual facilities otherwise all employees can not able to use all those features. On that note, purpose of this developing mobile application is not solved in a proper manner. In order to design this mobile application, there are used different advanced software application programs and platforms such as marvel and build fire for mobile application programming along with designing. In that regard, this project requires personal computer, laptop, mobile application platform, IT services and other software to fulfil all specification of this Qatar Petroleum. In order to build this app, software designers require supports from both software as well as hardware so that they can establish a connection between platforms and devices. For this project, this project does not need any funding along with subjects.

1.4 Constraints

Two major factors become constraints for this project.

  1. This app is designed to solve employee problems. However, targeted users are totally different from university working environments.
  2. Another problem is that this mobile app contains several software and libraries to provide staff support. In this case, those software and libraries do not support in IOS platform whereas it is feasible to build in Android platform or in desktop environment.

1.5 Project Approach

This mobile application is developed for the purpose of mitigating employee’s issues related to workplace as early as possible so that work performance level can be better. According to the company’s specification, software designers are trying to implement all those elements into this mobile app. However, software designers try to gather more information and ideas from employee so that they can obtain clear vision of all requirements. Based on that specification, this mobile application requires knowledge of web development, basic programming languages, and skills in mobile application design along with use app interface. On that note, this mobile should be user friendly and easy to use along with professionally developed so that it can be represented for Qatar Petroleum Company.

1.6 Project Deliverables

This project is based on to enhance the service quality with the help of software application program. Therefore, this application development process will take almost 4 to 6 months approximately on the basis of criteria. This project has to complete before real application. Entire software is developed to follow the development phase of waterfall model so that each specification can be fulfilled. In order to deliver this report, specification of each stage will be delivered and established. On that note, beta version of this application will be delivered before launching actual application so that problems will be identified. Based on those identified problem, testing is done to receive those issues to provide better quality of services. This software application program provides user guidelines and detailed instruction so that user can use this mobile application in an effective way.

1.7 Legal, Ethical, Professional, Social Issues

This mobile application requires personal information for register with this mobile application. In this case, this software application must be incorporated data protection law 2018 and UoP Research Data Management Policy to ensure data safety during using this application. All contains which are included as a subject in this project, will be over 18 years old along with providing data assent. Before hands-on research, official requirements will review as per The University of Portsmouth ethical review. All guidelines and paradigms are used under the guidance of professional experts of this University so that final submission will be held in a proper way. This app deals with organizational issues and social impact does not influence this app.

1.8 Project Plan

Project plan is developed to fulfil all criteria and purposes. Project plan helps to design entire work in an organized way so that project objectives will be solved within deadline. Entire project plan is portrayed in Gantt chart (MS project) so that anyone can easily understand the individual project task, responsible person, duration. The risks such as system design, debugging consumption are faced during software development process. In this case, time management is another issue to achieve milestone. [Refer to Appendix 1]

Chapter II – Literature Review

Service desk is an important information technology service management method which is a combination of different IT service management. This mobile app is developed to build service desk management for employers of Qatar Petroleum so that organizational; problems are solved at that point of time. In order to develop this mobile app, this software requires interface design, software life cycle development for development and white, black bio testing to identify bugs. In this section, information is collected from different secondary sources such as journals, books, and published web sources (Bober, 2014). This information helps to represent entire software designing planning in an effective way which can reduce complexity. In order to make this app easier, this app incorporates various technologies, software libraries, user friendly interference.

2.1 Shneiderman’s Rules of Interface Design

Software designers required to solve various problems day by day. In order to solve all those identified problems, they require a detailed investigation and search. Based on this information, they have to develop a plan and test this software before launching (Copenhaver and Koclanes, 2016). In this case, users always prefer user friendly interfaces. On that note, Shneiderman’s Rules of Interface Design helps to provide eight methods for improving usability of a software application with good designing.

  1. Strive for Consistency: –
    For enabling user friendly interface, software designers have to incorporate easy and understandable icons, colours, menu option which is familiar with users. In this way, user can easily recognize their desired options and they can follow sequences (Hockey, 2016). On the other hand, users have to apply their knowledge in finding options if software designer follows standardized option. In this case, users have to learn and follow the guideline to recognize perfect menu. On that note, consistency plays an essential role because user can easily familiar with digital landscape. In this way, product can achieve goals.
  1. Enabling Shortcuts: –
    User can easily find items by shortcuts which are enabled to improve user friendliness. As an example, Windows and Mac operating systems provide user shortcut for undo, copy and paste so that user can easily perform their task with the help of those key shortcuts (Jäntti and Cater-Steel, 2017).
  1. Offering feedback: –
    Users have that right to get informed about all activities happened in this mobile application otherwise user does not know about every activity (Keisling and Sproles, 2017). For an example, software updating percentage, picture upload provides information to all users about progress rate. Every feedback is to be more relevant, meaningful, fit with the context and clear.
  1. Easy Actions Reversal: –
    Users get anxious if they make any mistakes regarding wrong information providing in the time of login and transaction (Lemire, Rutledge and Brunvand, 2016). In this case, software des joiners enable an option which is called “UNDO”. This option makes everything simpler and user can revert back to that step which helps to prevent any mistake or accidents.
  1. Error Handling: –
    Every system should be designed flawlessly as much as possible otherwise any system related issues cannot avoid by users (Piccoli and Lui, 2014). In this case, software designers provide intuitive and simple instructions to resolve all identified problems so that user can able to use those guidelines to recover these situations.
  1. Supporting internal control: –
    When any clients use software application program, they can have the power of entire systems that they can change, modify or customize all options as per their choice (Sillanpää and Sillanpää, 2015). In this case, they can avoid unnecessary interruptions which are promoted during fetching data.
  1. Reducing short term memory loading: –
    Human has limited memory capacity for data processing. In order to avoid those problems, software designers have to incorporate information in interfaces so that users do not require remembering data (Stern, 2017). As an example, users have to insert data from one page to another. In this case, interactive user interface provides information to avoid this situation so that it can increase mastery, controlling over systems.
  1. Designing Dialogue: –
    Software designers develop systems which provide information while any task is completed. Otherwise users try to guess when it will be done (Xuan et al., 2016). In order to be an interactive system, it should be incorporated those facilities as that user understand easily by seeing dialogue box.

2.2 User Interface Heuristics

Heuristic evaluation is the usability inspection process for software which helps to recognize usability issues in user interface design. It involves specially evaluators exampling judging and interface its compliance with identified usability rules and principles.

  1. System Status Visibility: –
    System should inform users about current status and actions via appropriate feedback and visual cues within time. As an example, page loading, picture uploading percentage rate provide information regarding progress status to users. User interface must be interactive.
  1. Matching between real world and systems: –
    Every system includes multilingual facilities so that user can select their languages. In this way, they can easily order, and information given by systems and they can choose actions according to their preferences (Bandyopadhyay and Boyd-Byrnes, 2016). In order to make user friendly interference, system developer use easy coins, colours, menu option which is much familiar with users rather than standardized icons?
  1. Using freedom and control: –
    User selects wrong option due to lack of information. In this case, systems designer must keep there an option which is “EMERGENCY EXIT” so that they can transfer from that situation to a safe zone. In this case, it can save user data and privacy.
  1. Error Prevention: –
    Sometimes, system provides error messages to inform users that any problems happen by mistake. In order to avoid this situation, users have to click OK button to get rid of this situation and comment.
  1. Helping users diagnose, recover and recognize errors: –
    Every error message should be promoted in a simple language so that every user can understand and rectify problems. Systems designers do not use codes to interpret problems in a display box. Furthermore, system designers indicate problems in a simple way, and it should be constructive and precious.
  1. Standards and Consistency: –
    System designers have to use simple icons so that users can able to understand the meaning by seeing it without having the proper knowledge and information.
  1. Recall and Recognition: –
    System designers develop application software so that it can reduce the user memory. In this case, users do not need to recall information from dialogue box. System designers provide all possible instructions.
  1. Efficiency and Flexibility: –
    In order to improve interaction, system designers have to implement easy methods so that both experienced and inexperienced use can able to use this application more efficiently.
  1. Minimalist and Aesthetic Design: –
    Dialogued box should not use irrelevant information such as programming codes. In this way, user can easily understand all commands present in dialog box with the help of easy language and icons presentation.
  1. Documentation and Help: –
    In order to provide more interactive with user, every system must incorporate guidelines so that user can take help for future actions. Instructions are provided to make every activity much easier for users.

2.3 Accessibility Guidelines

This report is developed to provide all necessary information regarding development procedure of mobile application which is designed for IT service desk systems of Qatar Petroleum. In order to develop this mobile application, software developer has to follow few strict guidelines which are discussed below-

  • Qatar government has introduced data protection act 2016 to secure user’s personal information and transaction details. In this way, this mobile application has to maintain this law for more data protection.
  • This mobile application will be used by several users who will not aware of mobile. On that note, software developer has to keep that in mind in the time of application development that users can obtain a hassle-free experience along with this app is user friendly.
  • In order to provide more interactivity, this mobile application will inform users by sending push notification regarding new messages, work progress report etc.
  • In order to register with this mobile application, users have to submit their personal information and passwords. For providing more security, this application will accept only encrypted passwords (Barqawi, Syed and Mathiassen, 2016).
  • This mobile application will incorporate flexibility, maintainability, scalability for user friendly interference in iOS platform.
  • Service desk systems will provide necessary instruction such as user manual for easy access.
  • This mobile app will support multilingual facility so that anyone can access this in an effective way.

2.4 Service Desk Systems Issues

IT service desk system is the integral part for an organization to form a single point which can meet the communication requirements of both users along with staffs. In order to mitigate technological complexities, the requirements for greater diligence are to maintain those technologies available always and it has increased the demand along with changed scope of supports. IT service desk systems has a great impact on organizational performance in following ways-

  1. Identification of service request: –
    Service Desk is designed in this way so that it can recognize all difference between user’s requirements, categorized. Based on that information, it provides services to solve the issues automatically (Brax et al., 2017). In this case, this desk support also assigns the appropriate technician so that they can solve the actual problems on the basis of location, workload, and specification. Priority is assigned automatically with the help of matrix.
  1. Lacking of Intelligence: –
    IT service desk is designed to provide faster solution. In this case, it can also identify the property and requirements of each task on the basis of intelligence, recommendations and patterns. Moreover, service desk provides solutions depending on its effectiveness.
  1. Repetitive Tasks: –
    The major issue is the service desk system has to face same tracks daily and manage it in a proper way. It can waste time because it can easily provide solution to the basis of requirements of this task to proper technicians with the help of AI. Lacking of streamlined procedure can cost any organization in huge rate.
  1. Resolving productivity Problems: –
    Any capable IT service desk system is highly configured to identify issues and it keeps tracking of every incident. On that note, it can help to increase the productivity rate by solving problems on time.
  1. Increasing the complexity: –
    Service Desk system cannot handle huge number of requests at a time. In order to manage all these issues, this can increase the complexity with the help of automated process to resolve the problems.
  1. Management and Control: –
    User can track of all those issues by service portal, e-mails, SMS, notifications, web interference. In this case, interruption of services requires addressing for minimizing impact in business operations.

2.5 Current Trends

Technology is emerging in terms of landscape of business to enable new firm of business automation process and incorporating more data in embedding technology in daily experiences. According to current trends of IT service desk, it contains IT service management and technological influences.

  1. Self-Services: –
    Artificial Intelligence is the key of transforming end user self-services capabilities of IT desk services systems. Self-service support can provide basis of search of FAQ, knowledge-based information, identified issues to interactive diagnostic capabilities sets with the help of contextual users’ awareness. FAQ can provide 24-hour support systems to solve more problems in an effective way.
  1. Environmental Data: –
    Machine learning language helps to enable diverse data which is to be integrated and make more accessible for service desk staffs. It helps to identify in depth issues and diagonals them individually. After that, it helps to provide better mad faster solutions.

Chapter III – Work Plan

3.1 Introduction

This project is emphasized on IT service desk system. In order to develop this mobile software application program, system developer will follow few software development life cycles models so that those tools can provide easiest solutions in software designing process. Before starting developing a software programs, software designers have to know the basic requirements and specification after consulting with clients. Project plan has to be made on the basis of client’s criteria. Gantt chart will demonstrate the entire project work so that client will understand each step very specifically. In this case, solution will be recommended if client can find any issues or additional requirements regarding software development process. Software development can be done using various development models which are discussed below-

3.2 Waterfall Model

Waterfall model is known for its sequential designing process and all phases of this classical method are seen as the flowing downwards steadily such as initiation, analysis, conception, design, testing, implementation, maintenance, production (Alshamrani and Bahattab, 2015). This model follows sequential process of software development so that result of every previous phase becomes the input of next phases. Based on project planning, this model decides and recollects all the specification along with designs. Implementation has to be done on the basis of designs and requirements. In verification phase, testing is done to know about issues so that software modification can be prepared to resolve all identified issues. After all the above process, final phase is maintenance to keep consistency in software development process so that immediate services are provided on the basis if requirements or feedbacks.

Figure 2: Waterfall Model
(Source: Created by Learner)

3.3 Iterative Model

Iterative model is another implementation process of software development which focuses on simplified implementation. After that, this model identifies complexity and tries to solve all issues until the final software development process has been done. In order to start software development process, it segregates entire development process into several parts so that it tries to understand requirements before starting remaining work (Kazim, 2017). However, small specification turns into complex to maintain its quality. Development process continues until it finishes the entire implementation and all those processes are recognized as iterations. All processes are repeated to enhance software quality and adaptability.

Figure 3: Iterative Model
(Source: Kumar and Rashid, 2018)

3.4 Spiral model

Spiral model is a combination of systematic, sequential linear, waterfall and iterative model. It can easily recognize risks and provide solution to rectify those identified issues. This model releases the final product in terms of incremental view so that this model improves the quality of product iteration on the basis of criteria. It has four phases such as identifications, design, build, risk analysis and design (Kumar and Rashid, 2018). The diagrammatic representation of this model looks like looks and number of loops depend upon individual projects along with its requirements. Software designer will decide number of phases to develop entire project using this model.

Figure 4: Spiral Model
(Source: Kumar and Rashid, 2018)

3.5 Incremental build model

This model divides entire project into multiple standalone modules. The entire process goes through design, testing, implementation, verification and maintenance. In this development phase, this model consists of multiple software development cycles. In order to make every phase more easily, each cycle is managed by modules (Misra and Singh, 2015). The main advantage of this model is that software is developed very quickly, and this model is very flexible to adapt new features on the basis of good designs along with planning.

Figure 5: Incremental Build Model
(Source: Kumar and Rashid, 2018)

3.6 Agile Model

This model is a combination of incremental along with iterative process model. This model also focuses on client satisfaction along with adaptability by working delivery of software products rapidly. This model also segregates entire development process into multiple incremental builds which are provided in iteration (Pant, Hardwari and Kumar, 2014). This model follows unstructured way in comparison with another model. In this model, client gets the opportunity to make decisions and make changes during development process. In this way, issues can be identified in the middle of development phases. Project manager can face difficulties to set the timeline for large projects because client interactions can make too many changes.

Figure 6: Agile Model
(Source: Pukdesree, 2017)

3.6 Justification

This software program application named as IT service desk system can be built using software development life cycle model. This project is developed on the basis of few requirements. On that note, this project has limited timeline to design a service task system. In this case, waterfall model is effective for this software application program because this model is cost effective (Pukdesree, 2017). Other model is time consuming and costly than waterfall model. Based on project specification, client interaction may hamper the development process. Furthermore, risk analysis can be done and solutions will be provided before launching final product.

Chapter IV –Requirements

Software application program requires few specific tools in its development process using software development life cycle models which are discussed in aforementioned section. In this case, requirements analysis is done to provide information regarding tools which are required for IT service desk systems for Qatar Petroleum.

4.3 Results

4.3.1 User Analysis

Service Desk Management is a process of managing IT services desks that can form several points of contacts between IT service users along with IT service providers (Jäntti and Cater-Steel, 2017). In this case, this service desk application has been developed to provide appropriate services on immediate basis. In order to use this mobile application, staffs have to register with this app by providing irrespective personal details and work email id so that IT developer can restore all functionality if any problems may arise.  System would generate a secure link which would send to provide mail id and users can retrieve their existing account to solve their individual purposes. Contact information would help to recreate encrypted and protected passwords because system would generate ONE TIME PASSWORDS (OTP) to avail all operation through this service desk mobile application.

Users can choose one or more than one services on the basis of their requirements and necessity. There are provided several options of services such as administration, access, application software, cyber security, staff support, and hardware services. In this case, each option has multiple activities with detailed specification because there are different types of queries generated by users. Based on specific details, users can add list of services in their respective carts. In this case, they can create a new SAP account, block account, data transfer, and access to another staff’s network folder. Therefore, this services app would provide little restriction on the basis of user performance and their position. Administrators can only get those facilities to access other staff’s indoor motion and transfer data. These facilities are entirely protected from other staffs.

Based on their individual choices, all servicers are stored in cart on temporary basis.  This service desk application can provide entire details of service growth in their request details section which would show the approval of access request, access type and its appropriate justification. Users have to attach necessary documents. On that note, application and software provides numerous services such as ECM, QPNet app, Technical app. ECM is a collection is defined strategies process along with tools that can allow business to organize, store and obtain critical information for business, employees, staffs along with stakeholders. Enterprise Content Management can help in reformation of business strategies to deliver appropriate services for all employees and staffs.

(Source: Created by Learner)

5.1 Architecture Design

This designing process is a highest abstract version of these systems. Architecture design identifies software as the system along with many components interacting with each other’s. In this case, software designers have obtained the idea of proposing solutions to develop software. In order to develop IT service desk, software designers understand user specification by conducting survey.

5.2 High level Design

High level designing phase consists of several components to develop software (Piccoli and Lui, 2014). In these cases, this design divides entire tasks into multiple modules so that it can help to develop software in an effective way. This designing model understands modular infrastructure of every system along with interaction and relation between each other.

5.3 Detailed Design

Detailed design is the implementation stage of subsystems which discusses in previous two sections. Based on the specification, implementation is done by considering all modules. In this stage, logical structure is established for every module with their interfaces after communicating with each other.
