The latest insights on re-engineering work for AI

What you will learn in this article

  • Why traditional job architectures cannot describe how work actually gets done
  • What job architectures show and what they systematically hide
  • How skills frameworks compound the problem rather than solving it
  • Why AI exposes the limits of job-based models immediately
  • What a work architecture enables that job architecture never can


Job architecture is not wrong. It is simply no longer true enough to guide decisions in an AI-enabled enterprise.

Job architectures were built to support stability, compliance, and reporting. They were never designed to describe real work as it changes day to day.

Today, work changes continuously. AI accelerates that change. Yet most organizations still rely on job architectures that operate above execution and behind reality.

This gap is no longer theoretical. It is now a material risk.

Job architecture describes structure, not work

Job architectures exist to classify roles, not to explain how work happens.

In practice, most job architectures consist of job titles, levels, and a thin layer of contextual description. They are often maintained in spreadsheets, formalised in presentations, and eventually forced into an HCM system.

They primarily support:

  • Compliance and grading
  • Pay bands and levelling
  • Reporting and workforce classification

They do not describe how work is actually performed.

As a result, job architecture answers administrative questions well and operational questions poorly.

Job architectures hide the reality of work

A typical job architecture tells you what exists, not what happens.

Most job architectures can tell you:

  • Which roles exist
  • How those roles are levelled
  • How they map to pay or regulatory frameworks

They cannot tell you:

  • What work people actually do in those roles
  • How work differs inside the same job title
  • How work flows across teams
  • Where decisions sit
  • What has already changed

There is no reliable connection between:

  • Roles and the tasks performed
  • Tasks and the skills required
  • Skills and how they are actually used

The architecture floats above execution.

Job architecture is static in a world where work is not

Job architectures are slow by design and that design no longer fits reality.

Most job architectures sit outside execution. They are updated infrequently and governed by processes optimised for stability rather than adaptation.

That made sense when work changed slowly.

It no longer does.

By the time a role is formally updated:

  • The work has already shifted
  • New tasks have emerged
  • Old tasks are being done by tools or agents
  • Teams have already adapted locally

The job architecture is always behind.

Skills data makes the problem worse, not better

Skills added without task-level grounding create abstraction, not clarity.

When skills are layered onto job architectures, they are rarely derived from real work. They are usually:

  • Scraped from job titles
  • Inferred from market data
  • Normalized lists applied at role level

They are not tied to the tasks people actually perform.

As a result:

  • Skills look plausible but remain abstract
  • They do not explain performance or productivity
  • They cannot show how skills change as work changes

This is why many skills-based initiatives stall.

They are disconnected from execution.

AI exposes the lie immediately

AI does not change jobs. It changes work.

AI operates at the level of:

  • Tasks
  • Workflows
  • Decision points
  • The boundary between human and machine work

A job architecture cannot show:

  • Which tasks are automated
  • Which tasks are augmented
  • Which new tasks are created
  • Which roles are expanding or hollowing out

This forces leaders to ask the wrong questions:

  • Which jobs are impacted
  • What skills do we need

The real questions are:

  • Which work is changing
  • Which tasks are emerging or disappearing

The system cannot answer them because it cannot see the truth.

Job architecture fails because it operates at the wrong level

Job architecture is not poorly designed. It is poorly positioned.

It describes:

  • Structure without execution
  • Intent without behaviour
  • Design without evidence

Most organizations already know this intuitively. Job architecture matters inside HR and compliance. It rarely guides decisions about real work.

It is referenced when required and ignored when outcomes are on the line.

That is the signal.

Work architecture starts where job architecture cannot

Work architecture is the missing infrastructure for an AI-powered workforce.

Where job architecture defines structure, work architecture defines execution. It provides a live, operational view of how work is actually performed and how it evolves as AI is introduced.

A modern work architecture makes several elements explicit and connected:

  • Roles, role groups, and standardization - These provide consistency, clarity, and global alignment across the organization while still allowing work to evolve.
  • Tasks and subtasks - This is where real work becomes visible. Task-level clarity enables accurate mapping of human versus AI work, automation opportunities, and operational redesign.
  • Outcomes and responsibilities - These clarify what success looks like and connect work directly to business impact and performance expectations.
  • Skills required for tasks - Skills are linked to value-creating work rather than abstract role descriptions, enabling more accurate hiring, learning, and mobility decisions.
  • Compensation and reward bands - Pay is aligned to real contribution as work changes, supporting fairness across evolving and AI-augmented roles.
  • Career paths and pivot pathways - Mobility is designed into the system, helping people transition as work evolves rather than react after roles become obsolete.

Unlike job architecture, this structure does not sit outside execution. It updates as work changes. It reflects reality rather than documentation.

This is what allows organizations to:

  • See how jobs are actually changing
  • Govern AI at the level where it operates
  • Redesign roles based on evidence, not assumptions
  • Align workforce planning, skills, pay, and technology to real work

Why this matters now

Relying on job architecture alone is no longer neutral.

Without a work architecture:

  • AI changes work faster than leaders can understand
  • Roles drift while structures stay frozen
  • Skills strategies remain abstract
  • Control erodes quietly

Your job architecture is not malicious.

It is simply no longer true enough.

In an environment where work changes continuously, relying on something that cannot see work is not just outdated.

It is a risk.

Executive FAQ

Is job architecture obsolete?
No. Job architecture still supports pay, compliance, and risk. It cannot explain real work or guide AI decisions.

Why does AI make this problem urgent?
Because AI changes tasks and workflows first. Job-based models cannot see or govern that change.

Can skills frameworks solve this on their own?
No. Skills without task context remain abstract and disconnected from execution.

What replaces job architecture?
A work architecture that makes tasks visible and connects them to roles, skills, and outcomes.

What leaders should do next

  1. Stop treating job architecture as a source of truth for work.

  2. Invest in task-level visibility before scaling AI.

  3. Align HR, IT, and business leaders around a shared work architecture.
