3 © 2014 Fair Isaac Corporation. Confidential. A Brief History of Decision-Making Systems © 2014 Fair Isaac Corporation. Confidential.3

4 ► Mostly implemented with logic programming languages ► Applications were largely goal- oriented, or “backward chaining” ► Decision structure modeled as a hierarchy of goals The 80s: Expert Systems Source: 4

5 © 2014 Fair Isaac Corporation. Confidential. ► “Rules are a first-class citizen of the requirements world” ► Rules should be declarative, modular and independent ► Allowed the development of “forward- chaining” engines ► Bottom-up approach for requirements gathering (grouping of rules into rule sets) The 00s: Business Rules Source: 5

6 © 2014 Fair Isaac Corporation. Confidential. ► Decisions, not just rules ► Rules have meaning only in the context of specifying the logic for particular decisions ► Graphical representation of decision-making ► Top-down process for requirements gathering ► DMN is an upcoming OMG standard (think “BPMN for Decisions”) The 10s: Decision Modeling Source: gctnetwork.com 6

13 © 2014 Fair Isaac Corporation. Confidential. Decision Modeling for Requirements Analysis 13

14 © 2014 Fair Isaac Corporation. Confidential. ► DRA is a method for developing decision models (especially as requirements for decision services) ► Basic principles: ► Decision services encapsulate decision-making ► Decisions can be defined as answers to questions ► Discover decision requirements by asking what information is required ► Information is of three kinds: ► Business knowledge ► Input data ► The results of other decisions. ► Hence decision-making has a structure ► Requirements are collected using a structured workshop method: DRAW Decision Requirements Analysis (DRA) 14

15 © 2014 Fair Isaac Corporation. Confidential. A standard 5-stage process: 1.Identify the decision points 2.Define the top-level decisions 3.Decompose the decisions 4.Describe all nodes in detail 5.Define scope of decision services DRAW Method 15

16 © 2014 Fair Isaac Corporation. Confidential. ► Define the (new or changed) business process as a flow ► Identify all decision points separately from any other process activities ► Identify all places where data are collected and decisions are used 1: Identify the Decision Points 16

17 © 2014 Fair Isaac Corporation. Confidential. ► Establish decisions required at each decision point ► Define for each decision: ► Name ► Question and answer ► Results returned 2: Define the Top-Level Decisions 17

18 © 2014 Fair Isaac Corporation. Confidential. ► Select any decision ► Ask “What information is required to take this decision?” ► Consider: ► Results of other decisions ► Business knowledge ► Data ► Add nodes to DRD 3: Decompose the Decisions 18

19 © 2014 Fair Isaac Corporation. Confidential. ► Select any decision ► Ask “What information is required to take this decision?” ► Consider: ► Results of other decisions ► Business knowledge ► Data ► Add nodes to DRD ► Repeat until all nodes are decomposed 3: Decompose the Decisions 19

20 © 2014 Fair Isaac Corporation. Confidential. ► Until you have a complete DRD 3: Decompose the Decisions 20

21 © 2014 Fair Isaac Corporation. Confidential. ► Decision nodes: ► Detailed definition ► Knowledge nodes: ► Source of the knowledge ► Estimate of size and complexity ► Maintenance requirements ► Not actual rules! ► Data nodes: ► Source of the data ► Estimate of size and complexity ► Not full data model! ► All this can be documented in a DDD 4: Describe All Nodes in Detail 21

22 © 2014 Fair Isaac Corporation. Confidential. 5: Define Scope of Services 22

23 © 2014 Fair Isaac Corporation. Confidential. Decision Modeling as a Structural Principle 23

24 © 2014 Fair Isaac Corporation. Confidential. ► Interdependencies between decisions ► Dependencies on business knowledge (of all types) ► Dependencies on case data ► Dependencies on authorities DMN for Revealing Structure 24

25 © 2014 Fair Isaac Corporation. Confidential. ► DMN models organizational decision-making: human and automated ► Can accompany or precede business process modelling ► Can partition decision-making between people and systems ► Can partition system decisions between services ► Can further partition systems implementation work for project planning ► Between teams ► Between increments DMN for Partitioning Decision-Making 25

26 © 2014 Fair Isaac Corporation. Confidential. ► Business decision-making defined in the context of business processes and activities ► Business rules given meaning by the decisions which use them DMN for Contextualizing Decision-Making 26

27 © 2014 Fair Isaac Corporation. Confidential. ► Identifies BKMs: components of business knowledge ► Allows modelling of organisational knowledge ► Allows modelling of knowledge in most appropriate form: ► Business rules ► Calculations ► Analytic models ► Reveals points of adaptivity/ optimisation ► Encourages re-use of automated components (e.g. for compliance) DMN for Knowledge Management 27
