Describe the statement "no other part of work so crippler the system if done wrong"?

This line emphasises the importance of requirement gathering activity of a software system. Requirements play a very important role in software development. These requirements help us capture the goals and objective of the software system to be developed. Requirement gathering phase is so important that if it is not completed properly, then the developed product may not able to achieve the objective for which it is to be developed. Another important thing to note here is that if these requirements are not properly gathered then at later stages of software development it is very hard to cover the shortcomings left during this phase.
