Design is finding a set of Solutions (Design-Ideas) for a set of defined Requirements.






Overview of the Design-Process

• Analyse the Requirements
• Find & Specify Design-Ideas
• Evaluate the Design-Ideas
• Select Design-Ideas & Produce Evo-Plan

Design can be carried out in several ways. It can be based on tradition, on intuition, on dogma, on principles or heuristics. It can also be based on multidimensional quantified logic – this latter we would call “engineering” or “Systems-Engineering”.

“Design comes about entirely from the playing out of the Evolutionary algorithm.”
Blackmore in “The Meme Machine” (See page 205)


1. The Design-Process can be subdivided into the following Sub-Processes:
a. Acquire Stakeholder Requirements.
b. Identify candidate designs
c. Tailor candidate designs to current purpose
d. Decide on a finite set of designs.
e. Do design review.
f. Implement designs in development System and test their validity.
g. Revise Design if necessary.
h. Implement designs in final System.

“Heuristic: At some point in the project, freeze the design. …..
This Rule of thumb recognizes that a point is often reached in design where the character of a project, and hence the appropriate allocation of Resources, changes from seeking alternative Solutions to perfecting a chosen Solution. …. After this point is reached, a major design change runs the unacceptable Risk of introducing a fatal flaw because insufficient Resources remain to evaluate all of its ramifications.” Source: Koen03, p.35

''This quotation refers to b. (Identify) and c. (Tailor) above. It reminds us that the Design-Process is not merely one of finding a design, and analysing it. The selected design is likely to be Generic in nature, or was applied in a different set of circumstances than the current project. So, we must expect to “perfect the chosen Solution” so that it better fits the current Requirements and environment.
2. The reader might like to compare this simple Design-Process with the corresponding Design-Engineering Process (*501 Note 2). The Design-Engineering Process is characterized by rigorous use of quantified information. It takes a clearer position on “how” to design. The Design-Process decomposition above specifies “what” is to be done, but does not specify “how”.
