What is the best definition below of the difference between the Collect Requirements process and the Define Scope process?

Requirements are capabilities that are required to be present in the product, service or result that project is supposed to produce, in order to satisfy a formal agreement (which could be a Contract).

Scope the sum of product, service or result to be provided by the project.

Requirements define the product behavior. They indicate what is that users want from the product.

Scope indicates the activities that need to be done in order to achieve the requirements.

The Collect Requirement  process:

• Requirements documentation
• Requirements management plan
• Requirements traceability matrix

From the define scope process, the project scope statement.

A project scope defines precisely what is included and what is not included by clarifying the boundaries. It is counter-intuitive in many ways, because often organizations try to deliver more than was agreed upon, to exceed customer expectations.

This can be called ‘gold plating’, and can cause projects to overrun schedules, budgets and hence increase risk. It is very easy in performing collect requirements that folks will ask for more than they actually need.

To be in control of scope throughout the project requires close management of collect requirements, the details etc, and the processes. Any scope changes must be handled in a structured, linear, and controlled manner.

Each requirement is documented clearly along with its acceptance criteria as it is vital that the scope is well defined and clearly communicated.

The key to the success of scope control is to ensure that if any change is requested, that it is first evaluated, captured and documented and that no change should be implemented unless it is clear that it is necessary, and that the right authority has first been given for its implementation. It is important to compare this against the output from collect requirements.

From the planning process group perspective, the requirements for the product and project are first gathered, then the deliverables forming part of the product and the project scope are defined and documented, leading to the creation of the work breakdown structure (WBS)

Collection Requirement

The detail contained within the requirements that lead to a clear understanding of what is needed to satisfy the stakeholders so that their expectations can be managed. This key documentation is the touchstone from which the schedule, budget, quality specifications, resource plans, and risks emanate from.

The pre-requisites to the collect requirements process are the project charter and the stakeholder register. The project charter provides an overview of the project’s product, service or result and this is used to determine the requirements.

The stakeholder register lists all of the project stakeholders and it is important that the right stakeholders are involved in helping to explain the requirements along with the underlying needs from the earliest point in time of the project.

collect requirements – Requirements documentation.

This lays out what needs to be performed and justifies why each requirement is important.

Information captured here should include:

• The source of the requirement and the core business problem that is being solved
• How each requirement addresses the problem
• Relevant measurements for each requirements
• How existing business processes interact with the requirements
• Constraints and assumptions
• Predicted impact of the requirements on others
• Business, legal, and ethical compliance

collect requirements – Requirements management plan.

This is in effect, a strategy for how the requirements will be managed, and covers the team activities to both gather and then manage the project requirements. This document forms part of the project management plan, and covers how requirements will be obtained and decisions made, how the requirements will be documented, and how requirements changes will be managed.

Requirements traceability matrix.

Part of the requirements documentation includes the source of each requirement, and identifying the source is what this document does. Here the sources will be named, whether an individual, group or organisation. The source origin could be a legal requirement, or clauses within a contract. Additional information may include who owns the requirement for example.

Eight Tools that may be used for collection requirement

1. Interview

2. JAD or Facilitation workshop

3. Group decision making techniques

4.Focus Group

5. Group Creativity Techniques

6. Questioners and Surveys

7. Observation

8. Prototypes

Tools used for defining scope process

1. Expert Judgement- Taking help from techinical experts for developing relevant part of scope statement

2. Product analysis

3. Facilitated workshop.

4. Alternative Approach - Eg - Brainstorming

This is what i could think off.

thanks for invition ,,,,,,,,,, my choice is option C

I agree with Option C....................

Option c :

The collect requirements process defines customer needs. The scope includes not only the

requirements of the product, but the project scope including risks, constraints, and assumptions.

Answer : 

Requirements define the product behavior. They indicate what is that users want from the product.

Scope indicates the activities that need to be done in order to achieve the requirements.

Scope can achieve partial set of requirements when the requirements are implemented across multiple phases or iterations (if you are using Agile methodology) by scoping part of requirements in each phase/iteration.

In short, requirement is outward facing – specified by customer/business; and scope is inward facing – to be implemented by the project to satisfy requirements.

Agree with experts Option C, thanks.

Thanks for the invitation

agree with expert's answers

d. Both Collect Requirements and Define Scope use facilitated workshops as a tool and technique
