Product Design Precautions

When you design a new Product or Engineer an existing one; communications and documentation is important. Creating a satisfying solution is the main thing. If requirements and specs or not properly developed it can lead to blame-games, wasted time and spoils the reputation.

A firm also should do proper market study before the decision to design a product. Even a well designed product cannot be sold if it does not offer a cost-effective solution.

Product Design Precautions
  • Start Projekt {
  • Customer Interaction and Communication to make a specs sheet and drawing.
  • Block Diagram, feasibility, cost, risk, samples demo and study similar ideas.
  • Effective designs are cost effective within customer budget, draft BOM costing.
  • Circuit and Code design and get more inputs from customer and then freeze specs.
  • Build Dummy for ergonomics and discuss, Prototype and start test at site or simulate.
  • Calibration and testing and production documentation drafts final costs.
  • Pilot Production of a small batch, rigorous test batch, and freeze production documents.
  • Documents and Prototypes to be given to Production Engineering.
  • Production Engineering continue engineering maintenance and quality issues.
  • } End Projekt
