Fashion product development is the process that turns a design idea into a garment a factory can produce: concept and research, design, tech pack, sampling and fit approval, costing and sourcing, then pre-production and production.<\/strong> Design decides what the product looks like; product development decides how it is specified, made, costed and delivered. Digital tools such as 3D garment simulation and PLM do not change these stages, but they can reduce the number of physical sample rounds and keep everyone on the same version of the style.

The Stages of Fashion Product Development<\/h2>\n\n\n\n\n\n\n\n\n\n\n\n
Stage<\/th>\nWhat happens<\/th>\nMain output<\/th>\nWhere digital tools help<\/th>\n<\/tr>\n<\/thead>\n
1. Research and concept<\/td>\nTrends, customer needs, range plan, mood boards<\/td>\nRange plan, concept boards<\/td>\nShared boards and asset libraries<\/td>\n<\/tr>\n
2. Design<\/td>\nSketches, flats, colour and material choices<\/td>\nTechnical flats, first 3D or digital styles<\/td>\n3D garment design, digital fabrics<\/td>\n<\/tr>\n
3. Tech pack<\/td>\nSpecifications for construction, measurements, BOM and labelling<\/td>\nTech pack<\/td>\nTemplates, linked 3D and pattern data<\/td>\n<\/tr>\n
4. Pattern and sampling<\/td>\nPattern making, first sample, fit sessions, comments<\/td>\nApproved patterns, fit comments<\/td>\n3D fit review, virtual samples<\/td>\n<\/tr>\n
5. Costing and sourcing<\/td>\nMaterial and trim costing, supplier selection, lead times<\/td>\nCost sheet, supplier orders<\/td>\nBOM costing, material libraries<\/td>\n<\/tr>\n
6. Pre-production<\/td>\nGrading, marker making, pre-production sample, final approval<\/td>\nGraded patterns, markers, approved sample<\/td>\nGrading and marker tools, DXF handoff<\/td>\n<\/tr>\n
7. Production and delivery<\/td>\nCutting, sewing, quality control, shipping<\/td>\nFinished goods<\/td>\nPLM tracking, status visibility<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Stage names and the order vary by company and product category, and many teams run steps in parallel. The point is that every stage produces data that the next stage depends on.<\/p>\n

What Is in a Tech Pack?<\/h2>\n

A tech pack is the document set a factory uses to make a style. A good one is specific enough that a supplier can quote and sample without guessing. Common contents are:<\/p>\n
