If they can’t get the information they need, the developers have to make their own interpretations, which aren’t always correct.
Substantial effort is needed to fix requirement errors discovered after those requirements have already been implemented.
Pre-course assessment tools and post course reinforcement training is available through our free personal online training portal. Also included in the price for all public classroom courses, is coaching support to help you maximise the impact of your training in your job. We can provide Off-the-shelf training in the form of our classic courses, or we can provide bespoke training, tailored to your organisational goals and objectives. What sets us apart from many other training companies is that we guide you through your entire learning journey.
We work together with you to assess your skills gap, map out your individual learning path and offer you the resources to then help you reinforce and adopt new tools and techniques learnt from your training and apply them to your daily work.
Any measures you can take to detect errors in the requirements specifications will save you considerable time and money.
This article, adapted from my book (Microsoft Press, 2003), describes the importance of requirements validation and some valuable techniques to try.
Validation is the confirmation, through the provision of objective evidence, that the requirements for a specific intended use or application have been fulfilled.As the requirements for the solution are elicited, the business analyst and testing team develop and refine a master test plan which makes sure it incorporates testing strategies for detecting any defects in the requirements, solution or corresponding documentation.During this course, you will develop the competencies required to create test cases and scenarios as well as ensure proper test coverage according to the risk level.But without taking the time to validate the requirements, the risk of missing the mark goes up.Most software developers have experienced the frustration of being asked to implement requirements that were ambiguous or incomplete.
