7.3 IAI/LAHAV QUALITY DATA—AN ILLUSTRATION

7.3.1 IAI/Lahav Pilot Project

We illustrate the process of obtaining system and quality data using an avionics upgrade pilot project that was conducted at the IAI/Lahav division in conjunction with the international research project SysTest (see Appendix A). The aim of the pilot project was to develop a new avionics system for a transport helicopter (see Figure 7.4) as well as building several helicopter prototypes for delivery. System cost and quality cost data were obtained from several previous IAI/Lahav avionics upgrade projects, quality cost and time measurements during the pilot project and cost and time estimations provided by domain experts (Engel and Shachar, 2006).

The project replaced older designed avionics and a pilot control system with a modern system. The helicopter was also upgraded to support Search-And-Rescue (SAR) missions. In addition, IAI was to provide product support for several years. The following system characteristics, grouped into three categories, were identified:

Project Characteristics

  • Development Type. typical IAI/Lahav avionics project.
  • Project Development Scale. Full-scale development covering Definition, Design, Implementation, Integration and Qualification phases.
  • Project Lifecycle. Includes several prototype productions and 15 years of avionics system ...
