Adoption of our Space Missions Catalog has been strong this year.  But many of you have asked if and when the TruePlanning for Hardware Catalog could be enhanced for unmanned space applications, both earth-orbiting & planetary missions.  You asked, we are very soon delivering! For 2016, we will soon roll out an extensive listing of MCPLXSs and MCPLXEs, likely implemented in the Equipment Type input.  This new table of manufacturing complexities was developed specifically for use with the TruePlanning for Hardware catalog.  A combination of three sources of data were utilized:          I.            The PRICE Knowledge Network (KN),       II.            ...
While there was a time in my life when I was not a huge baseball fan – it was fun for a few innings but once I had my fill of hot dogs, peanuts and soda – I was ready to go home.  This changed the day my husband informed me that it was time to sign our four year old up for T-ball.  At least the transformation started that day.  As a mother of two up and coming little leaguers, I spent a lot of time watching baseball games.  And rather than be one of those mothers that ...
In 2015, the Systems Engineering Research Center (SERC) published the Software Cost Estimation Metrics Manual for Defense Systems. This manual presents the results of research conducted by SERC Researchers Ray Madachy and Brad Clark, who with the help of Barry Boehm, have documented the core metric definitions along with relevant and useful cost estimating relationships for software intensive defense systems. The e-book is available for download at the following link… http://cdn.sercuarc.org/wp-content/uploads/2014/05/Software-Cost-Estimation-Metrics-Manual-for-Defense-Systems.pdf What’s great about this manual is that it covers best practices specific to software systems in the areas of measurement, data collection, normalization, analysis, benchmarking, and CER development.  The ...
Last week I had the pleasure of attending the 30th annual COCOMO Forum in Arlington, VA.  As always it was an informative and enjoyable exchange of software and system estimating topics and challenges with some of the brightest practitioners in the industry.  Topics ranged from technical debt and software maintenance, early phase effort and schedule estimation, COSMIC function points and various data analytics topics.  In addition to the presentations there were several lively workshop panels discussing and debating future directions for the COCOMO and CoSysmo models (contemplating the 3.0 versions of each of these models. While all the talks were ...
For all you legacy PRICE-H users, your requests were heard loud & clear regarding estimation of multiple production lots, to include the option of specifying gaps between lot runs. The new Multi-Lot solution is controlled at the system-level via a Production Learning Gap Loss Factor  input.  It’s set at the top-folder object, under the Detailed Estimate input #62.  This input serves as a linear multiplier to adjust or eliminate the setback (gap) between lots of a multiple lot production run. This control hence allows you to account for more or less "loss of learning" during the gap.  Setback can be ...
We presented the results of an independent study last month at NASA’s annual Cost Symposium.  For those of you unable to attend, we thought it only fair to publish the highlights.  As background, the TruePlanning for Space Missions Catalog (“TPSM”) has been well-received since its official launch at last year’s Symposium by our Chief Scientist.  Since then, we’ve done Space-related webinars and multiple blogs, all available on this website.  However, what was impressed upon us by a longtime NASA customer, at the recent ICEEA annual conference, was that our users would highly benefit from a validation study that they could ...
We’ve wrapped up our first phase of research on the cost implications of Additive Manufacturing (AM), also known as 3D printing, and we have just begun phase two.  We teamed up with Additive Manufacturing groups in academia and industry, developed a research approach and estimating structure with the guidance of experts, and began collecting cost and technical data.  So far, we have gathered 648 datapoints from 3 organizations, which mainly includes data from 6 different printers.  The data are mostly for stereolithography (SLA) and direct metal laser sintering (DMLS) processes.  For our first cut at the data analysis, the ...
Original Post date: October 14, 2015 A few weeks ago I encountered a question from some users modeling an aircraft project with some prototypes and a number of production units.  They wanted to make sure that they accounted for the cost of upgrading the Prototypes to Flight/Production units, while using a fairly detailed product breakdown structure.  So the Prototypes would be built up with an initial design, and then certain parts would be upgraded after the design was refined to become full flight units.  Here are a few different ways to approach this issue: 1.       Additional Prototypes – The most simplified ...
Original Post Date: October 8, 2015 Excel is easily the most common and widely used tool in the Cost Estimation universe. It can be used as a scratch pad, report generator, import/export vehicle, data repository as well as countless other applications. The Excel / TruePlanning interface is one of the first topics new users want to dive into. Currently TruePlanning can export and import Excel files directly, create reports in Excel and has two Excel based solutions for working with TruePlanning directly in Excel. The ‘big gun’ of the Excel interfaces is the “Excel Solution”. It is a macro enabled ...
Original Post Date: October 8, 2015 Over the last couple of months PRICE has received a number of support calls related to an inability to import or export *.tpprj files from TruePlanning. When an import or export is attempted users are receiving an error indicating a “bad parameter or missing node”. The cause of this error has been a case of a missing XML library known as the MSXML4 library. MSXML4 had been installed as part of Windows operating systems by default for years, but newer versions of XML libraries have been created and are now used exclusively so new installations ...
