Strict
The overlap in TSS values is intentional and it depicts that sharp boundaries are impossible to define when making task set selection. In the final analysis, the TSS value, past experience, and common sense must all be factored into the choice of the task set for a project.

7. Example – SE Tasks for a Concept Development Project
Potential for new technology or new business idea is explored
No certainty of applicability but the potential is there.
Major tasks include:
Concept scoping
Preliminary concept planning
Technology risk assessment
Proof of concept
Concept implementation
Customer reaction to concept

9. Concept Scoping Sub Tasks or Activities Identify needs and benefits
Define desired output/control/input
Define the function/behaviour
Isolation software elements
Research availability of existing software
Define technical feasibility
Make quick estimate of size
Create scope definition

10. Identify Needs and Benefits
Meet with customers
Identify needs and project constraints
Establish project statement
Milestone: project statement defined

11. Define desired Output/Control/Input
Scope keyboard functions
Scope voice input functions
Scope modes of interaction
Scope document diagnosis
Scope other ‘Work Product’ functions
Document OCI (Output Control and Input)
FTR (Formal Technical Reviews) - review OCI with customer
Revise OCI as required
Milestone: OCI defined
