As many are aware, requirements analysis plays an important role in project success and even in iterative/agile methodology. Based on the latest research companies with poor business analysis capabilities will have three times as many project failures as successes. In addition, companies pay a premium of as much as 60% on time and budget when they use poor requirements practices on their projects.
Analysis of requirements plays an important role in any application/product development projects. The requirements must be elicited and analysed, and the client/product owner must validate and verify the requirements before reaching a consensus to start development. Prioritizing and defining the requirements in detail for the next development cycle needs requirements analysis.
Each requirement must be questioned with the golden rule of 5 W, What, Why, Who, Where, When?
These questions will arise during a few more discussions on the requirements and more clarity must be achieved in order to proceed without worrying about future requirement changes.
A well-defined requirement is complete, accurate, clear and can be communicated effectively. Requirements do not mention anything about design or how the project will be developed.
Ineffective or poorly defined requirements can adversely affect project success or cause major and costly rework. Even projects that employ Agile Methodology involve elaborate user stories in order to include every detail of the requirement and consider all possible scenarios.
The product owner envisages requirements and defines the scope of the product/application. Once development commences, the evolving product review leads to requirement enhancement for the betterment of the product/application.
Draw your thoughts
Any idea can be well understood using diagrams, requirements can be represented using wire diagrams, use case diagrams, state transition, flow diagrams, etc. Requirements should have diagrams to help communicate requirements to stakeholders. Presenting requirements using drawings helps to remove any possibility of ambiguity or miscommunication.
Effective communication plays a very important role in any vertical or field, it can significantly reduce the need for rework in software development projects.
The communication delay can lead to a major rework and hence affects the cost. Communication of requirement changes takes higher priority than any other task in the software development cycle. Avoiding surprises and communicating bad news early can increase customer satisfaction significantly.
Requirement Verification & Validation
Verification & validation of requirements in a developed product/application is a very important stage in the in development cycle. Business users/Product owners skip validation due to many reasons but unless validation is completed and approved, the product/application is not ready to Go Live.
