6 Study Area 1 - Introduction Introduction - Business modeling enables effective communication between staff involved in the analysis and design of business processes. The modeling activity produces diagrams which can form the basis of both new information systems design and business process re-engineering. Example Diagram from this Study Area
MIS: Pichai Takkabutr EAU 2005 7 Study Area 2 - Modeling Simple ScenariosDiagram Notation - This section explains the basic skills and knowledge needed to draw these diagrams, their structures and notation standards. Topics covered include: entities, data flows, processes, data stores and resource flows. Exercise 1 - Guides the candidate through drawing a simple business process diagram for a common business scenario.Context Diagrams - Introduces and then tests basic knowledge and skills in producing simple context diagrams as a way of documenting system boundaries. Exercise 2 - Shows the candidate how to draw a context diagram for a simple business system. Exercise 3 - Guides the candidate through the drawing of a context diagram for more complex business scenarios. Example Diagrams from this Study Area

MIS: Pichai Takkabutr EAU 2005 9 Study Area 3 - Conducting the AnalysisLevel 1 Diagrams - This section explains how to analyse and document the main functional areas of the system under investigation, with reference to previously drawn context diagrams.Resource Flow - Demonstrates how to identify, read and draw resource flow diagrams; this technique is a particularly useful start point where the business is concerned with the movement of physical goods or ‘resources’.Organisation Structure - Another view of a system, process or organization is from its functional perspective; this section teaches candidates to conduct this type of analysis.Document Flow - An organization which makes extensive use of either paper-based or computerised documentation can be examined from a document flow perspective; this section teaches candidates to construct document flow diagrams.Converting Document Flow - Explains the techniques used to convert the document flow diagram into the various diagrammatic components that make up a business process diagram.Exercise 4 - This exercise involves the drawing of a level 1 business process diagram using a context diagram and a document flow diagram; a detailed on-line case study supports the exercise.

MIS: Pichai Takkabutr EAU 2005 11 Study Area 4 - Refining the DiagramsSimplifying Diagrams - It is easier to produce complex and incomprehensible diagrams rather than simple but complete ones. This section explains how to simplify business process diagrams so that they are genuinely useful to everyone involved. Top Down Expansion - Having learned and practised the techniques for developing high level diagrams, candidates now learn to conduct top down expansion, or ‘decomposition’. Exercise 5 - Candidates are guided through the process of drawing a level 2 business process diagram by the top down expansion of an existing level 1 diagram; this exercise is also supported by a detailed on-line case study. Elementary Processes - An elementary process is one which requires no further analysis and this section teaches candidates how to identify and annotate elementary processes. Checking Diagrams - Having created business process diagrams the final and essential step is to check that they are meaningful, intelligible and complete; this section explains how to examine and verify the entire business model.
