Requirements Process And Documentation : Waterfall Model Essay

Understanding the business model of enterprise and identifying the entities of that model is the first step in setting up database. Requirements analysis includes tasks of determining the needs or conditions to meet. Requirement specification document will be generated at the end of this step.

Another way of successfully gathering information is by building a prototype or model of the system, so that users can test or get an idea of what the finished product will be like. With this they can determine issues, problems, or inconsistency with the system. Another important part of gathering information is organizing it so that it can be understood and put to proper use. I propose categorizing the requirements into functional requirements, operational requirements, technical requirements, and transitional requirements. The functional requirements define how the user thinks the system is functioning overall, the operational requirements define what background processes need to be executed in order for the system to work optimally over a period of time, the technical requirements define what technical issues that must be addressed in order to successfully implement the system, and the transitional requirements define the processes or steps needed to implement the system smoothly and successfully. ("Mind Tools", 2012).

The commonly used methods of observation, interviews, etc., can help analysts pinpoint exact requirements based on user input and business processes. According to Charvat (2003), “One of the biggest benefits of a proper user requirements specification is that you'll be able to plan and estimate your project correctly, decreasing the chance of cost and time overruns.” The analyst must listen to the employees and gain a thorough understanding of all business processes before establishing the new system requirements.

Business requirements document (BRD) that provides additional details regarding the expectations (such as user, system, and functional) that must be met for achieving project goals

The purpose of this section is to identify the documentation that will be used for ensuring quality.

Which is requirements needed, after all the information the team will analyze to determine software requirements and generate a report. Then we move to the selection and design, this will occur when the team creates several designs and share with everyone on the project. We will identify any weakness, if we have any successful prototypes it should show how the software will operate. Implementation phase should proceed without any issues if there is any it must be correct during this time. A planned out schedule should allow for any unexpected incidents. When the implementation stage is complete we move to operation when our software has been designed and does what it was designed to do. We will do a review and evaluation which consist of performance, cost and

2. During elicitation process the user requirements are agreed upon and are clearly defined and expressed in natural language, unambiguous and easy to understand. The requirements, defines the characteristics or operational objectives of the project. During validation, the document reduces the potential for dispute between customer and contractor allowing changes, misunderstandings and problems to be worked out ahead of time, before design and implementation of the system occurs.

In conclusion, the metrics and acceptance criteria will be determined for all requirements to provide a baseline of understanding the deadline of the requirements at a satisfactory level.

The information system’s requirements in the systems planning phase are based on a case summary, potential interview questions, and the systems analyst’s experience in systems planning. One must not only generate requirements based specifically on what users’ state they want or need. Analysts must also generate requirements based on insight into the overall organization and project goals.

Requirement Analysis: collect the business needs, document the requirements, and help team members to prepare Functional and enhancement Specification Document and Technical detail design document.

This will help me and the team to understand how the system works. The documents will serve as the reference point on the basic requirements. For cohesiveness, I will have the team to discuss my findings during meetings (Trotter & Uhlman, 2011).

These documents will need to be developed and tested to ensure that they meet the organisations requirements. I would have the staff that are responsible for using the documents to test the documents and provide feedback on these to ensure that they are suitable.

This is the phase where the requirements are noted, feedback regarding requirements are obtained from users

The interview session has been done by include an open-ended and closed-ended question which are related to the implemented project. Next, sampling technique is executed by system analyst who does evaluation to the current system or prototype. These processes give feedback in evaluation form that filled after tested the system. Lastly, observation is performed by using questionnaire form. According to Burch (1992), the questionnaire is analyzed and transform into structured form that easy to understand. After all information has been collected, structuring of system requirement takes place. It focused on development process modeling which perform “graphically representing the process, or actions, that capture, manipulate, store, and distribute data between a system and environment” (Hoffer, George, & Valacich, 2012, p. 182). In this step, Data flow diagram (DFD) is structured by system analyst using special tools and techniques to create a decision table. According to Hoffer, George and Valacich (2012), decision table is a “diagram of process logic where the logic is reasonably complicated” (p. 200). This table is useful to help system analyst to make a decision toward the project. Then all information’s gained from this phase are documented in System Analysis Report (SAR) that acts as a guideline or reference to the future system development project (Burch, 1992).

The requirements gathering and analysis phase is the most critical phase for the overall success of the project because this phase helps “identify and capture stakeholder requirements using customer interviews and surveys” (Smith, 2016). In order to successfully capture software requirements from the stakeholder, developers need to conduct conference meetings to understand the capabilities of the software. This conference meeting usually takes place only once, so it is essential that developers collect all the information required for the software during the elicitation requirement meeting. For developers to be successful in collecting all the required information, it is a
