In the spotlight

  • IFPUG and Nesma sign a Memorandum of Understanding: IFPUG and Nesma are very pleased to announce the signature of a Memorandum of Understanding (MoU) that will promote the technical cooperation between the associations. Click here for more information.
  • New guide criteria for measurable documents: This document (Dutch language) describes some criteria to determine if your documents can be used for functional sizing methods. The document can be download via this link.
  • New examples for FPA available: The Nesma standard has been renewed completely in 2018. One of the major changes was that the examples were issued separately, so that they could be renewed at a faster pace. Recently the Counting Practices Committee has released version 2021.1, containing 40 examples to illustrate the application of the standard in practice. Another addition in this version is an improved matrix that shows which guideline is illustrated in which example (also available as a separate download). The new examples can be downloaded for free from the Nesma website via this link and the matrix via this link.

Sizing and more

Nesma has its origin in measuring the size of software. Today, size and other metrics form the base for many activities that play a role in successful and cost-effective software projects.

SW Cost Estimating

Software Cost Estimation becomes a discipline in IT. Together with ICEAA, Nesma is involved in establishing a Software Cost Estimating Body of Knowledge (SCEBoK). The release is expected early in 2021.


Nesma offers a combination of both free and paid publications that are helpful for you as a metrics professional. Take a look at these publications and raise your level of knowledge!
