Steps to analysis
Getting started Current status Goal/vision Transition to implementation
Public Health Informatics: An Overview of Key Issues
Getting started
Determine scope, objectives Determine approach/methodology Identify project team Develop project workplan Obtain commitment/resources
Public Health Informatics: An Overview of Key Issues
Current status: where are we today? Organizational structure Document organizational goals and
objectives Preliminary functional business model
A function is any set of actions performed in the course of conducting business
A function is defined by its partsFunction=task=process=activity
Public Health Informatics: An Overview of Key Issues
Current status: where are we today? Organizational structure
Gather recent organizational charts(including originating and partner organizations) Department names and location People’s titles/position People’s names and contact information Reporting lines (direct and indirect) Number of people in department
Indicate relationships between organizational units

objectivesReview organizational goals and objectivesDetermine organizational critical success
factors Identify any political or controversial factorsProduce report of findings for review and
confirmation by administration
Public Health Informatics: An Overview of Key Issues
Current status: where are we today? Preliminary functional business model
Include all domains (major functional area) within organizational structure
Divide each functional area into its subfunctions (important to take time and careful notes when conducting this step)
Decompose functions using an iterative process until all functional areas and connected sub-functions are identified
Examine functions to determine if a new categorization or hierarchy of the functional business model appears to better describe the functions
Use an iterative process with team and stakeholders to determine if new functional business model

Goal and Vision: what needs to change? Review functional analysis Identify and interview/survey all stakeholders Analyze information gained to identify
significant findings and opportunities Develop project goal and vision Review project goals and vision with all

Transition to Implementation: what needs to happen? Meet with stakeholders to discuss project
implementation Develop appropriate sequence of actions
Systems/applications that create data should be developed before systems/applications that use data
Develop a plan for conversion from existing to new system
Maintain project monitoring
