The Sociotechnical Frame

Two systems, one outcome

The theoretical backbone: every work system has a social side and a technical side, and attending to one while ignoring the other reliably produces failure.

Two systems in every organisation

The sociotechnical model: Organisation, Social, Technical, TaskOrganisationSOCIALTECHNICALTask
The sociotechnical model (after Bostrom and Heinen). A work system has a social side — the organisation and its people — and a technical side — the systems, processes and tasks. The four elements are interdependent: change one and the others must move with it.

“A work system has two aspects: the SOCIAL system, which includes the people and how they fit into the structure of the organisation; and the TECHNICAL system, which includes the IT and automated processes, and the tasks they perform.”

Bostrom and Heinen

“Successful organizational performance depends on good interaction between the social and technical systems. Paying attention to either system on its own will create problems and barriers to success.”

Bostrom and Heinen

Placing the contention in the frame

Complexity sits between the social and technical systemsOrganisationSOCIALCultureTECHNICALProcessTaskCOMPLEXITY
complexity is generated in the interaction between the social and technical systems, and it lands on the task.

Map the contention onto the sociotechnical grid and it resolves into four quadrants: People and Organisation on the social side, Technology and Task on the technical side.

  • COMPLEXITY sits mainly on the technical/task axis — the number of processes touched, the systems involved, the time to implement.
  • CAPABILITY sits mainly on the social/organisation axis — the culture, the management style, the maturity of process management.
  • complexity is a property of the project. capability is a property of the organisation. Failure is a relationship between the two.
Capability equals organisational culture plus process managementOrganisationSOCIALCultureTECHNICALProcessTaskCAPABILITYCOMPLEXITY
capability sits on the same frame: organisational culture on the social side, process management on the technical side, holding the complexity that the project creates.

That refinement matters because it makes both sides measurable. If you can put a number on complexity and a number on capability, you can compare them before you sign the contract rather than after the write-off.

Key takeaways

  • Every change touches a social system and a technical system simultaneously.
  • Optimising one side alone predictably damages the other.
  • capability has two components: organisational culture and process management maturity.

Take it back to work

  • In your last business case, how much analysis went into the social system compared with the technical one?
