Business Architecture
Connects outcomes to capabilities, responsibilities and value flows.
When useful
When a problem crosses several functions and no single team can resolve it.
Question it helps answer
Which capabilities must work together, and who owns the outcome?
Not simply drawing an organisation chart.
Process Discovery
Examines how real cases move through people, information and systems.
When useful
When the written procedure does not adequately explain observed work.
Question it helps answer
What actually happens, including exceptions and invisible work?
Not the same as accepting an existing process map as fact.
Process Redesign
Changes the shape of work, dependencies and decision points.
When useful
When removing or simplifying work is more valuable than executing it faster.
Question it helps answer
Which steps can be removed, combined or made clearer?
Not automation of an unchanged process.
Systems Integration
Connects information and actions across system boundaries with clear contracts.
When useful
When people repeatedly bridge systems or updates arrive inconsistently.
Question it helps answer
Which events and identities need to cross this boundary reliably?
Not just wiring two APIs together without agreeing meaning.
Data Architecture
Defines business entities, relationships, identity and data authority.
When useful
When teams disagree about what a record represents or which source is authoritative.
Question it helps answer
What is this object, and where does each field belong?
Not just selecting a database.
Automation Engineering
Implements repeatable rules and reliable execution with monitoring and recovery.
When useful
When the inputs, rules and required outcome are sufficiently understood.
Question it helps answer
What is the correct result, and what happens on failure?
Not making uncertain decisions look deterministic.
AI / Agent Architecture
Designs reasoning, context, tools and action boundaries for AI systems.
When useful
When interpretation or unstructured information matters and a governed scope can be defined.
Question it helps answer
What should the model interpret, and which actions need verification?
Not granting an AI model unrestricted access.
AI Governance
Defines authority, evidence requirements, oversight and accountability for AI use.
When useful
When generated outputs or agent actions may influence meaningful decisions.
Question it helps answer
Who may approve this action, and what evidence must they see?
Not a policy document disconnected from operation.
Change Management
Helps people understand, adopt and sustain changed ways of working.
When useful
When a technically sound intervention changes responsibilities or established habits.
Question it helps answer
Whose work changes, and what support and feedback will they need?
Not persuading people to accept a design that ignores their context.
Product / Programme Leadership
Coordinates priorities, dependencies and delivery around measurable outcomes.
When useful
When several workstreams must deliver one coherent change.
Question it helps answer
What outcome matters, and which dependency is currently limiting it?
Not treating completion of tasks as proof of business value.
UX / Service Design
Examines the experience of people moving through a service, including internal handoffs.
When useful
When people cannot see what to do next or repeatedly compensate for confusing interactions.
Question it helps answer
What context does the next person need at this moment?
Not just visual polish on an unchanged workflow.
Domain Expertise
Supplies contextual understanding of a specific field, operation or regulatory setting.
When useful
When a generic rule misses important meaning or consequences.
Question it helps answer
Which apparently small exception changes the decision?
Not interchangeable with general technical competence.
Data Engineering
Builds dependable data flows, transformations and quality checks.
When useful
When analysis or operational decisions depend on inconsistent, late or incomplete data.
Question it helps answer
How will we detect missing, duplicated or stale records?
Not assuming a data pipeline establishes business truth.
Security & Privacy
Designs protection, access controls and appropriate handling of information.
When useful
When workflows expose sensitive information or grant tools authority to act.
Question it helps answer
What is the minimum information and permission needed here?
Not adding a security review only after access is granted.
Operational Excellence
Improves the reliability and effectiveness of work through observation and disciplined improvement.
When useful
When recurring variation, waiting or rework limits an outcome.
Question it helps answer
Which source of friction can we remove without shifting it elsewhere?
Not demanding speed without examining the system.
Knowledge Management
Makes useful knowledge findable, contextual, maintained and transferable.
When useful
When repeated escalation and expert dependence obscure how decisions are made.
Question it helps answer
Which examples and reasons should be preserved, and who keeps them current?
Not collecting documents without ownership or context.
