[Year 12 SofDev] Analysis: Scope vs requirements

Wed Aug 29 13:09:58 EST 2012

Hi all,

This is what I use with the kids

What is the Scope?

Wieger's defines scope as the portion of the ultimate product vision that the current project will address. The scope draws the boundary between what's in and what's out for the project.

Stellman & Greene define the scope as

This section contains a brief description of the scope of the document. If the SRS is a complete description of the software, then it will state something similar to: "This document contains a complete description of the functionality of the (name of project) project. It consists of use cases, functional requirements and non functional requirements, which, taken together form a complete description of the software." For complex software, the requirements for the project might be divided into several SRS documents. In this case, the scope should indicate which portion of the project is covered in this document.

http://www.stellman-greene.com/images/stories/Library/SRS%20Outline.pdf, <20/03/11>

I often talk about the requirements of the project being item 1-20, but the constraint of time or money could mean the scope will only include item 1-10.

Regards

Claudia

I must admit, when I get quotes for IT projects, the companies providing the quote usually give me a scope of works which includes the requirements of the job and what they are going to do for the money. The only addition might be some exclusions, eg does not include connecting to legacy devices.

So from my experience the scope includes the requirements, but also identifies the exclusions.

Hi all. During analysis, the 3 activities mandated by the study design's definition of the PSM are determining: scope, requirements & constraints.

I have been wondering for a while: doesn't determining requirements also define scope?

If they are different, how?

How do you good folk explain the difference to your kids when they ask (as one of mine did the other day, which meant I had to point dramatically into the air and then run away while he was distracted) ?
