The design process: an iterative model for developing a product, system or environment

What a design process actually is

A design process is the structured but flexible sequence a designer follows to move from an identified need or opportunity to a resolved product, system or environment. NESA frames the HSC course around designing and producing, so you are expected to both name the stages and show them working in your own Major Design Project (MDP). A serviceable model runs: identify the need/opportunity → research → generate and develop ideas → produce/realise → evaluate → (loop back).

• Identify the need or opportunity and write a statement of intent.
• Research primary and secondary sources to inform decisions.
• Generate and develop ideas through sketching, experimentation and modelling.
• Produce the outcome using appropriate materials, tools and techniques.
• Evaluate against criteria, then refine.

Why the process is iterative, not linear

The single most-rewarded idea here is that designing is iterative and recursive, not a one-way checklist. Testing a prototype almost always sends you back to redevelop an idea; new research can reopen the brief. Markers reward folios that show this looping — a problem found at production that forces a return to development is evidence of genuine design thinking, not a mistake to hide. This directly services outcome H1.2 (relating the practices and processes of designers and producers to the MDP).

The process is also holistic: each stage feeds the next, and decisions made early (materials, scale, budget) constrain what is possible later. A strong answer treats the stages as interdependent rather than isolated boxes.
