Embedded Market Forecasters (EMF) just announced the availability of valuable new research that analyzes the Return On Investment (ROI) of different middleware approaches. I'm happy to report that RTI Data Distribution Service outperformed both commercial and in-house alternatives in nearly every category EMF measured. Given this, it is not surprising that EMF also found RTI was the most widely used embedded middleware supplier.

This broad-based research provides the first independent quantification of the reduction in time, cost and risk you can expect from RTI Data Distribution Service. Findings include:

  • Up to 45% Lower Total Cost of Development: The average cost of application development was substantial for projects using internally developed "Roll-Your-Own" (RYO) middleware ($1.61M) and most commercial solutions ($1.34M); however, projects using RTI middleware enjoyed much lower costs ($0.89M).
  • Up to 47% Lower Cost Overrun: The average cost overrun was similar for projects using RYO (11.3%) and most commercial middleware (10.1%). Projects using RTI finished closest to expected cost (6.0%).
  • Lower Testing Costs: In projects where the cost of testing was less than 30 percent of the total development cost, RYO (72.5%) showed an advantage over commercial (65.5%) middleware. Projects using RTI's commercial middleware, however, had testing costs less than 30 percent of the total development cost 84.6% of the time.
  • Greater Probability of Meeting Design Requirements: Final design outcomes using commercial middleware in general, and RTI in particular, were much closer to pre-design expectations than RYO developments for performance, functionality, features and schedule.


This report was based on independent research and a comprehensive survey of developers conducted by Dr. Jerry Krasner, EMF's founder and principal analyst. Dr. Krasner is a widely recognized authority on embedded systems and has over 30 years of embedded industry experience.
