Find the guidance for your next decision.

Start with your work

A service change may begin with a business aim, a difficult handover or a security concern. Start with the question you need to resolve, then follow the links to the decisions it affects.

Starting point What it helps you examine
Business architecture Purpose, capabilities, value and the changes needed in people, work and information.
Process Activities, business rules, decisions and handovers.
Structure Organisational responsibilities, authority, skills and shared services.
Information Meaning, ownership, records and data use, including data governance.
Security Harm, protection, access and response, including Zero Trust.
Systems Applications, integration, software and business rules.
Technology Runtime, infrastructure, environments and technical recovery.
Deployment and operations Readiness for use, support, recovery and continuing improvement.

How the guidance connects

Business architecture brings several aspects of A Simple Architectural Framework (ASAF) together. In the fictional example, a cancelled course connects learners’ needs to the work, people and information needed to help them. Process covers the activities and handovers; Structure covers the roles and authority behind them.

Security has its own ASAF aspect and applies across the others. A change to a role, record, interface or supplier can change who may act and what needs protecting. The Deployment and operations guide also brings aspects together: a service needs people, procedures and support as well as working technology.

Direction and relationships

These aspects help connect a particular change to the wider organisation.

Aspect What it helps you examine
Purpose Aims, outcomes and priorities.
Customer People and organisations served, their needs and relationships.
Supplier Responsibilities, dependencies and the ability to change supplier.
Channel How people reach and use the service.
Management Direction, decisions, roadmaps and continuing oversight.
Finance Funding, commitments, costs and benefits.
Metrics Observations used to judge outcomes, quality and change.

The Framework explains the complete structure: aspects, process areas and levels of abstraction. Use Methodology configuration to relate it to your own terms and records, and Assessment to examine speed, quality and useful life.

Worked example and templates

Follow the worked example from a cancelled course to its proposed service changes. The Blueprint brings the design views and decisions together. Use the editable templates to record decisions in your own work.
