Dear Jiho Yoo, IFPUG volunteer leaders from committees and the Board of Directors are routinely working to develop resources to benefit our members and keep them informed of the latest information in the Function Point community.  The latest resource has recently been reviewed and approved for release by the Functional Sizing Standards Committee (FSSC) and IFPUG Board of Directors. Congratulations to Marcello Sgamma and Kiran Yeole for development of the latest IFPUG white paper. New White Paper: Applying Function Point Analysis to Microservices We are thrilled to announce a new IFPUG White Paper, “Applying Function Point Analysis to Microservices”. Microservice architecture is an emerging model in software architectural design, particularly in cloud applications, with customers often requiring it in bids or contracts, which transforms it from a technical aspect to a user requirement (functional or not functional). This paper provides some guidance in applying Function Point Analysis (FPA) to functional sizing of microservice architectures. This paper is a great resource for anyone needing to size an application designed with a microservice architecture through providing guidance in definition of most fitting boundaries depending on the sizing purpose, and demonstration of proper BFC identification in a microservice architecture.

Boundaries & Partitions White Paper

Setting the boundaries correctly has crucial importance in the sizing process. It affects the product size (both functional and non-functional), hence it influences effort estimation and the Key Performance Indicators (KPIs) of those sizing units. The setting of the boundary is influenced by the purpose of counting. Therefore, different guidelines should be applied for each sizing purpose. The purpose of this document is, in part, to guide users of the International Function Point Users Group (IFPUG) functional and non-functional sizing methodologies how to set the boundary and partitions correctly; a partition is a non-functional subdivision of a boundary (to be discussed more fully later). It supports the IFPUG Function Point Counting Practice Manual (CPM) for IFPUG function points (FP), the IFPUG Software Non-functional Assessment Process (SNAP) Assessment Practices Manual (APM) for IFPUG SNAP points (SP) and Simple Function Point Counting Practices Manual for IFPUG Simple Function Points (SFP).

Using the General Systems Characteristics with the Software Non-Functional Assessment Process (SNAP)

This white paper discusses the relationships between function point sizing, SNAP point sizing, and the GSCs, and recommends how to avoid an overlap between SNAP and the Value Adjusted Factor (VAF) by using the Modified Value Adjusted Factor.  For many organizations, this should improve the accuracy of their software sizing.
