Why measure Design Development Why measure Design Development Process Performance?Process Performance?
Management of processes/activities supported. Communicate. Control. Recognise.
Measured representation of processes/activities. Factual Decision Making. Trends.
Improve/Optimise Process Performance. Redesign. Identify Strengths and Weaknesses

Weaknesses of Current SolutionsWeaknesses of Current Solutions Advocate a balance of weightings and
considerations and not reflecting organisational objectives.
Focus on the identification of performers (non-performers irrelevant?).
Lack the identification of change feasibility and sequence issues.
Lack an overall index and sub-indices. Lack the quantification of relations. Promote the application of pre-defined goals and
intuitive measures. Propose generic business frameworks (lacking
dynamic nature).

Definition of strategic composition and deployment.
Goal orientated composition of metrics not defined.
Metrics applied erratically and intuitively. Relationships not defined. Retrospective not Prescriptive. Specialisation and generalisation of measures
(Meaning).

SummarySummary Develop a methodology which extracts the supporting
infrastructure (Meta-Knowledge) that enables Design Development process performance behaviour to be: Acquired Analysed Categorised Interpreted
Develop a means to manage and re-design process activities and architectures through an understanding of process performance behaviour.
Provide a powerful means to initiate ‘What if’ process design analyses based on generated knowledge of process performance behaviour.

Then Depth is between 17 & 23
Given a span width of greaterthan 30 m, then use 3D spaceframe.
