TSS Degree of Rigor < 1.2 Casual 1.0 – 3.0 Structured > 2.4 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.

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

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

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

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
