We are building something fundamentally different.

Advisory OS is not a consulting methodology, a knowledge repository, or an AI initiative. It is a cognitive operating system for advisory services which combines:

• Consulting methods
• Organisational knowledge
• AI-enabled workflows
• Human expertise
• Governance and assurance
• Commercial attribution

into a single, repeatable operating environment.

The role will be responsible for designing, codifying, evolving and governing this operating system. This role sits at the intersection of consulting, operating model design, knowledge management, AI, organisational architecture and systems thinking.

The successful candidate will translate expert thinking into scalable structures, workflows and methods that can be used repeatedly across advisory and consulting engagements.

The objective is simple:

Convert consulting from a people-dependent craft into an institutional capability that improves with every engagement.

Design and evolve the Advisory architecture including:
Pattern catalogues, Method packs, Workflow definitions, Assurance mechanisms, Knowledge structures, Governance models, AI-enabled delivery journeys.

Create operating artefacts which are practical, scalable and directly usable by practitioners.

Codify expert consulting thinking into:
Playbooks, Decision trees, Diagnostics, Frameworks, Hypothesis models, Red-team processes, Evidence standards.

Move the organisation from templates and slideware toward a reusable intellectual architecture homed in AI and accessible by all, with usage governed and attributable.

Design and maintain:
Knowledge taxonomies, Metadata structures, Version control approaches, Knowledge lifecycle processes, Knowledge quality controls.

Ensure organisational knowledge remains trusted, curated and reusable.

Work with Consulting, Data, Security and Technology teams to develop AI-enabled workflows across:
Retrieval, Analysis, Verification, Challenge, Synthesis, Learning capture.

Ensure AI augments rather than replaces professional judgement.

Establish a culture of learning through:
Pilot design, Workflow testing, Adoption measurement, Outcome assessment, Continuous refinement.

Operate with a product mindset rather than a project mindset.

Work closely with the Director - BT Advisory, senior Mission Advisers and the Advisory community, consultants and technical experts to:
Capture tacit expertise, Identify repeatable patterns, Improve methodologies, Strengthen proposition development.

Support the creation of new consulting and advisory capabilities and propositions.
