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.
