7. Tool support

Question 1

Management of requirements tools should support

Answer 1

1. definition and storage of requirements attributes to identify and collect data about work products and requirements
2. Facilitation and documentation of the prioritisation of requirements
3. life cycle management, version control, configurations and baselines
4. tracking and tracing of requirements as well as defects in the requirements and work products
5. change management for requirements

Question 2

Requirements engineering process

Answer 2

1. measure and report RE process workflow
2. information helps to improve the RE process and reduces waste
3. measure and report on the product quality
4. information helps to find defects and flaws

Question 3

Documentation of knowledge about the requirements

Answer 3

1. sharing and creation of the common understanding of the requirements
2. securing the requirements as a legal obligation
3. an overview of an insight into the requirement

Question 4

Different types of tools

Answer 4

1. management of requirements
2. requirements engineering process
3. documentation of knowledge about the requirements
4. modelling of requirements
5. collaboration
   6 testing and/or simulation of the requirements

Question 5

Introducing the tools

Answer 5

1. describe the objectives, context and requirements before selecting and implementing appropriate tools
2. tools do not solve organisational or human issues
3. can help you to configure the process effectively and efficiently, provide framework based on best practices

NB RE process can be change due to new tool

Question 6

Aspects to consider for tool introduction

Answer 6

1. life cycle costs
2. necessary resources
3. avoid risks by running pilot projects
4. assessing tools based on definition criteria
5. instruct employees on the use of the tool

Question 7

Tool evaluation criteria

Answer 7

1. project perspective (support project and info required in the project)
2. process perspective
3. user perspective
4. product perspective
5. supplier perspective (service reliability of supplier, how is support arranged)
6. economic perspective
7. architectural perspective (does it fit IT infrastructure)

Question 8

Life cycle tool costs

Answer 8

1. purchase / licensing costs
2. less visible costs: the use of resources in the implementation, operation and maintenance of the tool

Question 9

Test the tool to reduce the risks

Answer 9

1. apply to a non-critical project/system
2. use the tool redundantly alongside an existing project
3. apply the tool to a fictional situation/project
4. import/copy the requirements of a project that ha already been completed
