This presentation looks at the role of business modeling when developing software in the healthcare industry. The importance of understanding the customer needs and domain is something that should be applicable across different industries. In particular, this presentation is from the perspective of a former aerospace system engineer.

2. From Aerospace to Healthcare:
Perspectives on Business
Modeling

Senior Systems Analyst
McKesson Medical Imaging Group (MIG)
3. From Aerospace to Healthcare …
Aerospace refugee (ex-Hughes/Raytheon)
Air Traffic Management – STARS, …
Air Command and Control – ACCS
“Systems Engineer” (SE)
Healthcare immigrant (ALI/MIG)
Radiology Information Systems (RIS) - HRM
Picture Archiving and Communications Systems
(PACS) - HRS
“Systems Analyst” (SA)
4. Overview
Meeting customer “operational needs”
From SE perspective
From BA perspective
From Healthcare perspective
Workflow Redesign
What are we doing at MIG?
6. Systems Engineering
Emerged in 50’s driven by US DoD
Applied to large system acquisitions, e.g.,
missiles and missile-defense systems
Mandated disciplined development
MIL-STD-499A
“A logical sequence of activities and decision
that transforms an operational need into a
description of system performance parameters
and a preferred system configuration”
8. Operational Concept
How the system will serve its users
Operational need definition
System mission analysis and performance
Operational sequences and environments
User and maintainer roles
9. NATO Air Command and Control
System (ACCS)

11. Business Analysis
IIBA (www.theiiba.org)
“The business analyst understands business
problems and opportunities in the context of
the requirements and recommends solutions
that enable the organization to achieve its
goals.”
15. Healthcare and IT
IT is relatively new to Healthcare, e.g.,
Hospital Information Systems (HIS), Electronic
Healthcare Records (EHR), Computerized
Physician Order Entry (CPOE), …
Key drivers
Patient Safety – “To Err is Human …”
Efficiency/Cost
Buzzword: Workflow
24. ALI/MIG
Then …
“Four people in a room and 6 months later …”
Workflow Redesign
... and now
Over 200 in R&D and growing
“Whither the business model?”
25. MIG Requirements Process
Functional Analyst create business model
Enterprise and Usability Analyses
E.g., Business Use Cases, Personas, …
Systems Analyst create system model
Software Requirements and UI design
E.g., System Use Cases, Interaction Design, …
Process being test driven as we speak
27. E.g., Critical Test Result Reporting
1. The interpreting physician detects critical
condition in study.
2. The interpreting physician sends critical test
result to the referring physician, which is
logged.
3. The referring physician is periodically reminded
to retrieve the message.
4. The referring physician acknowledges receipt,
which is logged.
5. Hospital administrator creates critical test
reporting communications report.
28. Conclusions
Operational <-> Functional disconnect
Issue across domains and industries
Software WILL impact workflow
Workflow redesign
Business modeling a necessity
Business Use Cases help transition customer
workflows
