Easy Functional Sizing - How to Create A Product Baseline
Master Functional Sizing with AgileBenchmark
€49.00€29.00
A product baseline is the total functionality delivered by an information system at a given moment, expressed in function points. It serves as the definitive "source of truth" against which every user story, sprint, or release is measured. Without a baseline, teams can measure sprint deltas, but they will never truly know how large the product has grown, making cross-team comparisons of productivity, cost, and quality pure guesswork.
This practical guide is entirely dedicated to that essential one-time investment: establishing a complete, defensible Easy Functional Sizing (EFS) baseline from whatever functional documentation is available—whether that includes user stories, functional designs, screen mock-ups, entity-relationship diagrams, or even a running application.
What You Will Learn:
The Full Step-by-Step Process: A clear sequence from gathering functional documentation and defining system boundaries to data model denormalization.
The EFS Simplified Rules: Master counting with only three core function types—Logical Files (LF), External Inputs (EI), and External Outputs (EO)—while staying closely aligned with Nesma Definitions and Counting Guidelines (version 2.3).
Handling Complex Data Structures: Learn how to apply the FPA-table rule, discard pure key-key junction entities, and evaluate entity dependence versus independence.
Five Real-Life Worked Examples: Practical walkthroughs ranging from a library management system and a helpdesk ticketing application to an online recruitment platform, a hotel reservation system, and a subscription billing engine.
Sustaining the Baseline: Step-by-step guidance on how to keep your baseline alive, updating rows row-by-row after every sprint or release.
Designed as the essential companion to "How to User Stories with Nesma Easy Functional Sizing," this e-book provides the exact framework you need to make your software measurements repeatable, auditable, and fully comparable across teams, suppliers, and time.
