Development Time Compression

A number that corresponds to the factor of time decrease - when tasks are done in parallel as opposed to sequentially - in an open source product development process. This requires Swarming and Module Based Design

OSE has demonstrated significant Milestones in development time compression - such as:

• 2021 - One Hour Walls - we have documented that the build time of the first floor walls of a 500 sf footprint Seed Eco-Home is 1 hour 18 minutes, with 8 people working and rest watching. If it tool 3.5 hours for the first floor, top plate, rim boards, and roof joists - then this entire type of house can be framed in a day. This is scalable to more people working, such that with a highly-coordinated team, it would take 30 minutes for the walls and probably 4 hours for full enclosure. At this small scale, it is likely that 4 work teams are an effective limit, and only a higher level of choreography can allow more people to partake. However, the larger the structure, the more people can work -
• MicroTrac v17.10 built in 5 days in a public workshop with about 12 people
• FIrst 5 day build of a 1400 sf home achieved, with exterior finished but not interior. Seed_Eco-Home#November_2016_Build
• 2016 - One day build of 3D printer achieved in 2016, using an open source kit - where 12 3D printers were built in one day for people to take home with them.
• 2013 - Full size tractor built in 5 days with 8 people. See LifeTrac 5.
• Redesign/build of the ironworker shear in 2 days instead of 6 months of the previous version in 2012. See Ironworker 3.
• 2012 - Industrial productivity achieved on a small scale, with the first 1 day build of a heavy machine - the CEB Press - was achieved with 12 people.
