We’ve kicked off a study on the cost impacts of various quality assurance standards, and this post gives our preliminary results for modeling DO-178c and DO-254 in TruePlanning®.  DO-178c and DO-254 are standards that deal with the safety of software and electronics used in airborne systems.  It began as a standard used predominately by the U.S. Federal Aviation Administration (FAA) for commercial aircraft, and its usage has spread significantly to the U.S. military and many other countries. All of the software and electronics on-board an aircraft are categorized into 5 Design Assurance Levels (DAL) based on how failure of ...
Original Post Date: Friday, November 7, 2014 We’ve recently completed a case study using TruePlanning for Microcircuits to examine the cost impacts of using newer technologies.  Recently, radar T/R module designers have begun substituting Gallium Nitride (GaN) substrates in place of Gallium Arsenide (GaAs) substrates in their designs.  GaN chips can handle significantly more power than GaAs chips, which enables significant performance benefits, while reducing the size/number of chips needed in each module.  But, are the newer GaN chips affordable? The IC fabrication process for GaAs circuits is very similar to GaN circuits.  There are, however, some important differences between these ...
Original Post Date: Wednesday, May 12, 2010 From my perspective as a cost researcher, the calibration tool is one of the most powerful analysis capabilities built into the TruePlanning cost management software . One way I can use this tool is to go back to an old estimate for a project that is now completed, and analyze the correctness of the previously entered input values. With this analysis, I can find ways to improve our methods of soliciting input values from the user to ensure the best values are entered the next time. This way, the TruePlanning models keep getting “smarter” as new information ...
Original Post Date: Friday, June 4, 2010 One of the great features of the TruePlanning cost management software is the fact that it makes it easy to handle complications of inflation and estimating projects performed in different countries and currencies. The costs associated with doing work in different countries, and the relative value of different currencies is constantly changing. To address this, the cost research team at PRICE does an annual economic update performed by the cost research team, and this blog will introduce some of basic concepts and research that goes into maintaining this feature every year. The price of goods and ...
We’re often asked about how to model the cost impacts of various quality assurance standards like SEI Capability Maturity Model (CMM) and CMM-I for software, DO-178c and DO-254 for airborne software and electronics, various MilSpecs, and even process standards like ISO-9000.  As a result, we’re kicking off a study to create new and updated modeling guidance for use with our cost models. Many of these standards have significant overlap, and an implementation of one can give you a head start in implementing another.  For example, DO-178c and DO-254 are design assurance standards, which basically says that if you follow these ...
