Writing project requirements

The difference, however, is that you will be giving out instructions that are based, not on your own purpose, but for a third-party user—the customer.

Writing project requirements

Thursday, 31 January Put most simply, a requirement is a need. This problem, this need, leads to the requirements, and everything else in the project builds off these business requirements.

Importance of Requirements Requirements are considered by many experts to be the major non-management, non-business reason projects do not achieve the "magic triangle" of on-time, on-budget, and high quality.

Very few projects do an effective job of identifying and carrying through the project and all the requirements correctly. Various studies, have shown that requirements are the biggest problem in projects. Projects fail due to requirements problems, the most defects occur during the requirements phase.

Project teams need to do a much better job on requirements if they wish to develop quality software on-time and on-budget. Furthermore, requirements errors compound as you move through a project.

The earlier requirements problems are found, the less expensive they are to fix. Therefore, the best time to fix them is right when you are involved with gathering, understanding, and documenting them with your stakeholders who should be the source of your project requirements.

The hardest requirements problems to fix are those that are omitted. The analyst often does not know what questions to ask, and the stakeholder does not know what information the analyst needs.

The requirements phase is also considered by many experts to be the most difficult part of any project due to the following: The requirements phase is where business meets IT information technology. Business people and IT people tend to speak different "languages.

Important Points to Consider

Building Valid Requirements The requirements analyst truly is responsible for the failure or success of the requirements on a project. With that at stake, building valid requirements up front is crucial. The four steps to this goal are: Elicitation The term elicitation is the industry-accepted term for getting the requirements from the stakeholders.

Elicitation, however, implies much more than just capturing or gathering the requirements from users. The truth is, one of the surest ways to fail in requirements is to say to your users, "Give me your requirements," then stand back and "catch" them.

The stakeholders are experts in their domains. While the analyst probably has more expertise in the IT domain, the two speak different languages. The stakeholders truly do not understand exactly what IT needs to be able to develop an effective system for them. So the only way for a project to obtain comprehensive, correct, and complete requirements from all stakeholders is to truly elicit them.

Elicit means to probe and understand the requirements, not just capture or gather them. The reality is that the quality of the requirements depends on the quality of the solicitation of them by the analysts.

Analysis Analysis involves refining or analyzing the stakeholder requirements into system, then software requirements. Analysis is a critical step, that is too often omitted or bypassed in projects.

Analysis is the critical transition from stakeholder or business terminology, to system or IT terminology. Analysis is usually done in conjunction with various modeling techniques.

Modeling-creating diagrams using standard notations-allows analysts to more fully understand processes and data in a rigorous manner. This understanding allows them to convert the often non-rigid stakeholder requirements into more concise, rigid system and software requirements.

Common modeling techniques include the following: Traditional systems Dataflow diagrams to understand processes and activities Entity-relationship diagrams to understand data Object-oriented systems: UML Unified Modeling Language diagrams, especially class diagrams for analysis, but also possibly collaboration diagrams Specification The specification sub-phase involves documenting the requirements into a well-formatted, well-organized document.Project teams need to do a much better job on requirements if they wish to develop quality software on-time and on-budget.

Furthermore, requirements errors compound as you move through a project. The earlier requirements problems are found, the less expensive they are to fix. The format of the requirements depends on what works best for your project.
