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

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

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
