  4. What Is a Function Hierarchy? • Represents business processes independent of organizational, geographical, or political boundaries • Shows how the business fits together • Results from functional decomposition

  5. Process Models and Function Hierarchies Where can I model . . . The detailed steps in a function/process? PM/FHD The sequence of steps? PM What starts it off? PM What results from it? PM Where it fits with the rest of the business? FHD The data it uses or produces? PM/FHD The materials it uses or produces? PM Who is responsible for it? PM/RON

  6. Vertical View Vs. Horizontal Organizational Capability Reparenting Automation Functions Business Rules as Functions Documentation Capability Organizational Preference Why use FHD instead of PM?

  7. Building a Function Hierarchy from Scratch 1. Identify the top-level or root function. 2. Decompose the functions. 3. Group subfunctions. 4. Remove all references to mechanisms. 5. Identify common functions.

  8. How to Decompose Functions Collect information List candidate functions Write a top-level function Decompose and include functionsfrom the candidate list Review for completeness and relevance Feedback to others Decompose to elementary level and add detail

  9. Elementary Business Functions • Take the business from one state of consistency to another or do not change the state of the business at all • Must always continue to conclusion or be totally undone If an intermediate step is valid, the function is not elementary.

  10. Atomic Functions • Defined as those on lowest level of hierarchy • Elementary Business Functions may be atomic (most frequent case) • Could be composed of atomic functions

  11. Stop Decomposing When . . . • The hierarchy: • Is accurate and self-contained . • Covers the scope. • Can be read. • The names are succinct and meaningful. • The functions have been sufficiently decomposed.

  12. Documentation in PM • Automation Check Box • Timing and Cost Analysis (Main,Resources) • Presentation (Multimedia) • Descriptive Documentation (Text)

  13. Documentation in FHD Immediate = Form Overnight = Report

  18. Common Functions Terminatemembership Managedelinquentmemberships Requestreturn ofoverdueitems Invalidatemembershipof delinquent customer Identifydelinquentmembers

  19. Are the Functions Really Common? • Do the functions carry out the same processing? • Do the functions manipulate the same information? • Do the functions have identical decompositions?

  20. Combining Common Functions 1. Identify common business functions. 2. Trace the route back up to the common parent. 3. Replace the common functions with a single function.

  21. Beware of Mechanisms! Mechanism: We take the customer’s photograph and stick it to the bottom left-hand side of a blank card. Wefill in all the member’s details on the card. Finally, we cover the card in plastic before giving it to the member in person or mailing it to the member. Business Function: Issue new membership card
