Cost and schedule risks in space projects can be minimized by applying technical concepts successfully flown previously to the subsequent missions. Examples from the development of three cold infrared instruments are discussed: ISOPHOT on ISO, PACS on HERSCHEL and MIRI on JWST. The progress achieved over two decades in the development of opto-mechanical elements like cold focal plane chopper and cold filter wheels will be demonstrated. While the instruments became larger and more complex, eventually the development consortia grew up to 20 institutes involved per instrument, requiring increasing resources for interface handling and coordination activities.
