“Process” is a step-by-step planning in resolution of
problems with identified inter-relation and sequence
between the steps.
When facing problems, the common mistake is to
immediately jump into the execution details without
an overall, from beginning to end, problem solving
“process”.
Depends on the situation, the “process” may not need
to be in detail to start with. The “process” can be
modified or enhanced during execution.
Concept of Process
3
Without a proper pre-defined “process”, most likely,
it will lead to lengthy iteration in solving problems.
The “process” can also be used to align all the involved
parties to work with the same pace. This is extremely
important for large scale projects, e.g. satellite design.
Concept of Process
“Process” can be presented as flow
chart with waterfall concept, i.e. top
down from coarse to detail.

Following chart provide a typical process related to the spacecraft structure design. It is not intended to be a standard solution, but rather to be a reference information for the homework problem.
Structure Design HW #2
Q: Generate a detail flow chart for spacecraft structure
design, from requirements to verification.
