Software Requirements Specification Case Study for the Team Project

Case Study for the Team Project

Making decisions across the Department of Defence project portfolio capability requires a comprehensive understanding of hundreds of projects and their interdependencies. The traditional way of looking at portfolio for decision-makers is often too complex to comprehend and visualise all the relationships between the projects and related risks. To be able to understand projects interdependencies from different perspectives when there is imposing change, or emerging risk, is often a challenging task for decision makers. Dealing with various constraints, and required business capabilities and benefits is critical for strategic decision-making and it requires awareness of related implications.

The aim of this project is to design and develop a prototype software system that is capable of capturing and processing project data, mapping interdependencies and enabling visualisation against the current state, or emerging change. The main goal of the system is to help users get a better visual overview of departmental portfolio to support their critical decisions.

This will need to work within a restricted ICT departmental environment, which implies security constraints as limitation to a number and type of commercial or open source deployable software packages like database and frameworks. This is an important requirement that requires research at an early stage of project study and requirements analysis.

Software design shall use best practice when dealing with the design to tackle the complexity and modularity, processing speed and data validation and storage. System design shall capture functional and non-functional requirements, business processes/flow, business rules and other important components.
Software Engineering Practice (S2, 2015) Case Study for the Team Project
The new system shall consist of two basic parts, which is data entry, first processing and mapping, and second is the visualisation. Basic functionality shall consist of the following modules: assets, resources, stakeholders, project and program management, interdependency mapping for projects and programs allowing different project elements like milestones or risks, as mapping attributes. These elements will be stored in system register and categorised by attributes. Design of this register is an important part of the system due to a need to reuse it across the different modules. At this early stage the complete set of elements is not finalised but it is known that it should consist of all project and program elements and attributes.

The unique set of the major elements is program, project, requirement time, cost, task, milestone, risk, asset, resource, constraint, stakeholder etc. More details can be found in additional reference documentation.

Database design shall use normalisation (up to the 3NF) for design to reduce the duplication of data and ensure referential integrity. It is important to cater for future changes and new functionalities. For example, there is a requirement to build user module with role-based access to system functionality. System must protect the data integrity during data input and its processing operations. The system must prevent the data loss by validating data input and protecting the data integrity from wrong entries or data processing.

Visualisation of the project data is a crucial component that requires functionality to present project maps or dependency charts via graphs and maps for a given set of projects or programs within a given time frame.

Each team shall determine further details on system functionality through brainstorming, researching and communication. This is an important task and if it’s not done thoroughly and properly the cost and the consequences of its payoffs may affect the experience through the unit and final grades.

Some aspects of the system requirements are left ambiguous, intentionally. It is a part of the learning process necessary for understanding of the system and it’s requirements correctly. Use the research and discuss it with your peers when required. In additions to this case study you should read through the three papers listed in references section and get familiar with the problem. This knowledge is crucial not only for the understanding of the system you are going to build, but also for the effective work on your requirements and your assignments. Your ideas and approach and quality of your system will contribute in your grade.

Software Engineering Practice (S2, 2015) Case Study for the Team Project
To satisfy this assignment minimal functionality required by your online modular system must have the following:

• Project Program and Portfolio management component with search functionality

• Project details search, edit and modify and delete

• Project interdependencies mapping with other projects

• Registers resources, stakeholders, assets, project elements and other required registers

• Interdependencies mapping functionality for Portfolio, Program and Project against the list of projects

Following functionality will be required for those aiming at higher grades (2 or more):

• Visualization of project tasks (Gantt chart) based on given project and filters like time frames, milestones, dependencies, risks etc.

• Program visualization of project and interdependencies in a one or many different graphs based on a given criteria

• Ability to remove one or many projects from visual representation to estimate gaps and effect on a program or portfolio level

• Enable export or interface to statistical tools like “R” or “MathLab”
Some of the provided documents contain the visualisation of the project dependencies, to help you create the system.
