Business Process Analysis Methodology for Information System Requirements Definition and Logical Design

This presentation outlines the elements of business process analysis and demonstrates examples of its application in various industries. It explores the importance of understanding business processes in public health and provides a framework for assessing and improving these processes. The presentation also covers the concepts of context diagramming, task flow diagramming, and information system support.

  4. WAYS AN ORGANIZTION CAN CHANGE

  5. BUSINESS PROCESS ANALYSIS (BPA) DEFINITIONS • Business Process: A set of related work tasks designed to achieve a specific desired business objective. The process result may be customer or market oriented or internal to the organization. • Business Process Analysis: Defining the task set required to support the achievement of the business objective. • Logical Design: Design of the Information System User Interface needed to support the performance of each task in the business process task set.

  6. WHY CONSIDER BUSINESS PROCESSES IN PUBLIC HEALTH? • Belief that public health only “delivers services” -hinders more comprehensive evaluation of underlying business processes • Public Health Departments are in fact businesses -their products and services can be defined and are similar across departments • Best practices are a derivative of the associated business process • Understanding the business practices helps optimize the use of information system requirements and content across all health departments

  7. WHY CONSIDER BUSINESS PROCESSES IN PUBLIC HEALTH? • One must understand the way in which work is done before one can explore ways of improving or streamlining it. • Public health is always being asked to “do more with less”. Becoming more efficient in the way in which work is done is one way to stretch limited resources. • Understanding how work is done now is a baseline for evaluating and adopting all or parts of a best practice model.

  8. A HISTORIC BPA EXAMPLE • Ford Motor Company -- Highland Park 1913 Automobile Assembly Paradigm prior to 1913: Result: Time cut from 750 minutes to 90 minutes/car through work simplification • What enabled Ford to build Highland Park? • In 1915 Highland Park employed 7,000 people. Why didn’t other companies follow this example?

  9. ANALYSIS FRAMEWORKS • Functional Decomposition: process of continual sub setting • Functional Analysis: a) logical process of building a framework and then fleshing out the details one logical step at a time b) the result of functional analysis is parallel to “assembly instructions ”for a product rather than a “parts explosion” (e.g., assemblies, subassemblies, parts) • Use Case Analysis: Typically a random walk if multiple use cases are involved

  10. FUNCTIONAL ANALYSIS • How do you work a 1000 piece jig saw puzzle? Step #1: __________________ Step #2: __________________ Step #3: __________________ Step #N: __________________ • How do you know when you’re done? • What does it mean if there are still “holes” in the puzzle? • What does it mean if you have “extra” pieces when there are no “holes” left?

  11. BASIC MODEL(INPUT-PROCESS-OUTPUT)

  12. THE KEY QUESTIONS IN DEFINING A BUSINESS PROCESS • What are the tasks in the task set that define the business process? • How are the tasks related to one another? • How is the process initiated? • What is the goal/objective associated with the performance of the business process?

  13. OUR APPROACHThree Step Sequential Process • Step #1: Context Diagramming: Designed to identify the participants (know as entities) which are the stakeholders in a given business process and the interactions between them. • Step #2: Functional Flow Analysis: Identify the interactions and/or transactions associated with each entity that trigger a set of tasks to be performed or represents achievement of the business goals/objectives. The sum of all the task sets creates an integrated description of the work that defines the business process. • Step #3: User Interface Logical Design: Each task identified in the analysis is examined to define the corresponding screen or set of screens needed to fully support the user in the performance of the task.

  14. CONTEXT ANALYSIS

  15. EXAMPLE PROJECT CONTEXT DIAGRAM

  16. FUNCTIONAL FLOW ANALYSIS

  17. TASK FLOW DIAGRAMMING • Concept of “turning the Context Diagram inside out” • A transaction or set of transactions pointing to a given participant (entity) either: • trigger a set of tasks to be performed • represent the goal/objective of the business process • Tasks must be identified and defined at the discrete level. In another sense, a task can be defined as “what goes on between the in-basket and the out-basket” • The task flow tool set is the same as standard flowcharting (primarily boxes, decision diamonds, and arrows)

  19. PERSON DEMOGRAPHIC PROCESS

  20. CASE INVESTIGATION

  21. USER INTERFACE ANALYSIS

  22. LOGICAL DESIGN CONTENT • In general we break the logical design out into a number of sections based on the segmentation of the functional flow analysis. Each section utilizes the same format: a) Introduction to the section contents b) Associated Functional Flow Diagram c) Associated Screen Navigation Diagram d) Screen mock ups, text description of the content and purpose of each screen and navigation buttons to access other screens e) Logical Data Structures associated with screens in section
