National Services Business Analysis and HL7

Martin Whittaker, Touchstone Consultancy Ltd [email protected]


What are National Services?

• Interaction between Spine and national systems– Spine Services– New Common Applications and Services – Existing National Applications– Knowledge Sources


What is Business Analysis?

• Scope the domain• Agree scope with stakeholders (clinicians, DA,

suppliers…) • Document business processes, including

assumptions and issues• Define comms requirements• Hand over to comms team


Domain Scoping

• What business areas are included?– OBS/Schedules– Talk to stakeholders– Talk to DA


Problems

• Nobody has done this before• Speed

– Detailed design in OBS• Confidentiality• Stakeholders have very different views


Document Business Processes

• The business processes don’t exist yet• Reality changes, eg

– TMS maturing – PDS/NSTS situation


Define Comms Requirements

• How far can you assume the solution?– Messaging?– HL7 V3?

• Data Dictionary vs HL7 codelists


The Ideal Way

• Fully-sorted design model• Two strands:

– Commercial documents (OBS etc)– Design documents


The Practical Way

• Constraints– Political pressures– Confidentiality– NHS traditions

• Result– OBS is design document– Consultation is limited


Benefits

• Speed• Political success• Commercial satisfaction


Risks

• Incomplete analysis– Incompatible solutions in different areas– Technical cul-de-sacs

• Lack of clinician & staff consultation– Incomplete take-up

• Lack of supplier consultation– Incompatible solutions

• How proven is the solution?


Successes

• Contracts have been placed• A lot of work has been done• Most stakeholders happy


What Happens Next?

• Understanding of suppliers’ solutions• Proof of the pudding• HL7 approves the messages

– Localisation???


“May you live in interesting times”
