Original Post Date: Thursday, August 23, 2012 We’ve bought access to IHS Haystack, which links us to huge amounts of data on government parts and logistics, including electronics running the gamut of technologies, functions, and types of equipment.  The tool combines data from more than 70 military and commercial databases, and includes detailed data on costs, procurement histories, and a wide range of technical characteristics – perfect for building and validating CERs. This data will be very useful for our TP 2013 Electronics Update.  All of this data can be built into a knowledge base and made available to TruePlanning users.  With this ...
Original Post Date: Tuesday, July 3, 2012  Introduction Cost estimate models are developed for many reasons: bids and proposals, should cost analysis, or measuring the state of a project already underway. Frequently many estimates are created using the same sources of data in an organization. By creating a custom integration solution based on the TruePlanning COM API repeated model creation can be automated. This can save considerable time, significantly increase the quality of the estimates by removing hand typed data errors, and speed up the time it takes to produce and gain value from cost estimate models. By example, this blog ...
Original Post Date: Tuesday, July 3, 2012  Introduction A cost estimation model needs to be fed data, and it is only as good as data used to create it. Frequently the data needed to ‘feed’ the cost model comes from a variety of sources including engineers, subject matter experts or other individuals not directly building the cost model. Just asking these experts to stick their finger in the air and take a guess isn’t always the best approach. Using the COM enabled Data Input Form Excel solution that comes with TruePlanning can help users obtain the data needed to complete ...
Original Post Date: Tuesday, July 3, 2012 Introduction @RISK and Crystal Ball are two Excel based applications that allow users to perform uncertainty, sensitivity or risk analysis on data contained in Excel spreadsheets. The analysis can be performed using various techniques including Monte Carlo and Latin Hypercube.  Many TruePlanning users are interested in performing this type of analysis on the models they create in TruePlanning or may even have requirements to perform this type of analysis on their estimates.   In response to this desire, PRICE Systems L.L.C. has created two Excel based solutions that allow users to easily leverage the ...
Original Post Date: Monday, July 2, 2012  The COSMIC method for counting function points arose out of concerns that the IFPUG (NESMA, FisMA) function points are too concerned with data intense business systems and subsequently are not adequate for adequately measuring the size of real time systems.   The COSMIC function point counting method has been designed to be applicable to both business systems such as banking, insurance, etc and real time software such as telephone exchanges and embedded systems such as those found in automobiles and aircraft.  The COSMIC method uses the Functional User Requirements as the basis for the ...
Original Post Date: Tuesday, June 19, 2012 In my last blog, I talked about the major research study on electronics being undertaken by the PRICE cost research team this year.  So far, we have visited modern electronics facilities, interviewed electronics experts, and visited customer sites to discuss their electronics estimating challenges. Among other things, we want to revisit and improve our “Manufacturing Complexity for Electronics” calculator.  This calculator guides users through a process of describing the electronic components being modeled, in a way that helps them quantify the complexity.  The first steps involve describing the equipment type, and technologies used.  ...
Original Post Date: Monday, June 18, 2012 This week I’m attending the Better Software Conference in Vegas.   I just attended a great keynote given by Patrick Copeland of Google.  The topic was innovation.  He talked about how innovators beat ideas, prototypes beat prototypes and data beats opinions.  These sentiments are all part of the pretotyping manifesto. He started with the truth that most new products and services fail and proposed that while this is not unexpected, there is a good way to fail and a bad way to fail.  The good way to fail is to fail fast.  ...
Original Post Date: Tuesday, June 5, 2012 Ever wonder what programming languages are the most productive?  I recently did a little research into this topic using the International Software Benchmark Standards Group (ISBSG) database. The database contains over 5000 data points with size and effort data for projects from a wide variety of industries, applications and counties.  Of course not all 5000 data points were suitable for my investigation.  The software size is measured using functional size metrics but the database accepts projects that use various counting methods.  I narrowed my search to projects that used the International Function Points ...
Original Post Date: Monday, April 16, 2012 This year, the PRICE cost research team is kicking off a major research study on electronics.  The field of electronics changes very rapidly, and we want to ensure our estimation methods are well suited for the latest technology.  While we constantly collect data and update relationships, this study will go above and beyond the norm.  We'll visit modern electronics facilities, interview experts, visit customers to discuss their electronics estimating challenges, and start a major data collection and analysis effort.  In the end, we plan to add many new electronic classifications, reexamine our ...
Original Post Date: Thursday, April 5, 2012  Introduction The previous blog covered getting started with the TruePlanning API using VBA. Now it is time to tackle collections. Collections in the TruePlanning API are simply objects that hold a list of objects where all the objects are of the same type.  For example, the Project object contains a collection of the Cost Objects that belong to the project.  In order to use the TruePlanning API, mastering collections is essential, but “mastering” is a bit strong a word given that they are easy to use. By the end of this blog TruePlanning API ...
