Scope is the place where we translate user needs and business objectives into specific requirements for what content and functionality the product will offer to users.
Strategy defines strategic goals(both product objectives and user needs), while Scope defines the features and content requirements that will fulfill these strategic goals.
It gives a clear description about what we are building, and how it related to our goals. and Yes, we can’t define a scope with 100%, and say this is exactly what is going to be, because new things are going to come during the project, but, if we defined boundaries of what you can and can’t do in the Scope, it will be much easier.
Defining scope makes us to address potential conflicts, and the bottlenecks from implementing the features before design and development.
Defining scope gives a reference point for client and developers about the work that’s going to be done. Documentation of the Scope doesn’t have to be a novel, but a common understanding of the features, schedules, and milestones puts everybody on the same page, and gives them a common reference.
It also gives a common language for talking about that work, like when you say “job vacancies search form”, now everybody knows what you are talking about.
Defining scope gives enables you to see connections between individual requirements that wasn’t clear, and organize related requirements, which may help then in determining which structure is appropriate for your product.
Having a defined set of requirements allows you to assign responsibility for the work, so no body will have a conflict about who is responsible for what tasks.
More features are coming during the project. Because there is information coming to the light and So, suggested changes or new features should also be documented.
Having a list with set of features to be implemented can help in determine which features can be done now and which has to wait until the next iteration.
We start by generating the requirements, negotiate, prioritize and finally we document the requirements.
