Planning
Examples of project planning Gantt charts
- Price Enquiry, Pre-series, Production
(pdf,
mpp)
- Minimal 8 months from Price Enquiry sent out until reception of series production (experience shows it's often longer, see below).
Development times
- Design and production time for Open Hardware designs (2013)
(pdf,
Excel)
- Conclusions (spoiler alert!)
- V1 is not (i.e. never!) suitable for series production. Designs need usually two to four versions before being production ready.
- Highly resourced projects take two years from design start to series production. Others need almost three years.
- When components are provided by CERN, it usually still takes a company one year to produce a series. Pre-series are needed.
- Conclusions (spoiler alert!)
