1. Change Management: The initial requirements from customer leads to development but as the work progresses, fresh requirements or changes in the existing requirements keep pumping in from customer end. There is no wonder about it to happen and one should take it as a natural phenomenon. After releasing their initial set of requirements, customer think tank keeps pondering over what else could be achieved which lead to these requirements. Critical part is to grab these requirements with a positive note, analyze well and segregate these requirements to two parts – to be added, or to be reverted back to customer with a justification for not adding it.
2. Commitment: For business critical apps development there is a deep rooted commitment required from each section, from each of the stakeholder. If that does not happen, there are chances of missing some important handling in time that could lead to a big disaster if raised at a later stage. It has been seen that if customer key users are not engaged well in time initially during the development phase for clearing off units built have higher risk of facing major setbacks in progress of project.http://itknowledgeexchange.techtarget.com/quality-assurance/impact-of-changes-in-requirements-and-commitment-on-project-delays/
