Excerpt from Improving the Reliability of Function Point Measurement: An Empirical Study: October 1991 Information Systems development has operated for virtually its entire history without the quantitative measurement capability of other business functional areas such as marketing or manufacturing. Today, managers of Information Systems organizations are increasingly taken to task to measure and report, in quantitative terms, the effectiveness and efficiency of their internal operations. In addition, measurement of information systems development products is also an issue of increasing importance due to the growing costs associated with information systems development and maintenance. One measure of the size and complexity of information systems that is growing in acceptance and adoption is Function Points, a user-oriented non-source line of code metric of the product of systems development. Recent previous research has documented the degree of reliability of Function Points as a metric. This research extends that work by (a) identifying the major sources of variation through a survey of current practice, and (b) estimating the magnitude of the effect of these sources of variation using detailed case study data from actual commercial systems. The results of the research show that a relatively small number of factors have the greatest potential for affecting reliability, and recommendations are made for using these results to improve the reliability of Function Point counting in organizations.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book.
