The Mistake I Keep Seeing Organisations Make with Job Architecture 

Sara Hill, Founder & CEO, RoleMapper, explains how harmless tweaks can end up destroying your job architecture

There’s a pattern I encounter far too often, and it can set organisations up for years of unnecessary complexity. A transformation lands. A new operating model reshapes reporting lines, shifts teams and redefines responsibilities.  

HR and Reward are then instructed to “update the job architecture to match the new structure.” The request sounds logical and it feels aligned to strategy.  It’s also the moment many organisations unknowingly weaken the long‑term stability of their job framework. 

The dangerous assumption that everyone treats as common sense 

The instinct is simple: when the organisation changes, jobs should change too. Operating models evolve with strategy, so adjusting the architecture feels like the responsible thing to do. 

But operating models are built to shift. A Job architecture isn’t.  

One is intentionally dynamic; the other exists to create consistency. When job frameworks change based on every structural update, they stop functioning as the anchor they’re meant to be. This is exactly why I created RoleMapper, to keep job architecture stable while everything around it changes. 

How "harmless tweaks” wreck your job architecture over time 

The drift begins quietly.  

A role profile is edited, a level is altered, and a title shifts to match a new reporting line. Each decision feels harmless in isolation, but eventually, the accumulation becomes visible.  

Roles that should be comparable begin to look unrelated because of where they live in the organisation and level definitions stretch to accommodate exceptions. The architecture starts to reflect the organisation’s structural history rather than the actual value of the work. What’s framed as adaptability becomes a source of inconsistency.  

Operating models are built to shift. A Job architecture isn’t

It complicates pay decisions, creates friction in governance and introduces differences that become difficult to defend. 

One of the biggest benefits we see in RoleMapper is the ability to surface these divergences early, before they become systemic. 

When your org structure starts dictating work value, not the actual work 

At this stage, leaders often feel uneasy without knowing why. Roles positioned close to influential teams can suddenly seem larger than they truly are. Not because their scope has expanded, but because proximity creates a narrative of increased importance. 

This is when pay gaps emerge and title inflation creeps in. Under pay transparency rules, these distortions turn into visible risks.  They aren’t easy to justify and they certainly aren’t easy to fix. Our analytics make these distortions visible in a way leaders can’t ignore 

The hidden damage to careers that organisations don’t notice until too late 

As job architecture begins to follow organisational shape, career pathways also become tied to that structure. Progression only makes sense as long as the operating model stays stable. Once it shifts, clarity dissolves. People get stuck because their growth depends on a structure that no longer exists.

This quiet erosion of career mobility undermines trust and damages the idea of a consistent, organisation‑wide approach to capability. 

The agility illusion. How leaders accidentally slow everything down 

Leaders usually tie job architecture closely to the operating model because they want the organisation to be nimble. The intent is greater agility. The actual outcome is slower change.  

Each shift triggers debates on levelling, pay calibration and governance. Decision‑making becomes heavier. Complexity grows. Transformation loses momentum. A design intended to enable agility ends up restricting it. 

What job architecture is actually for  

The organisations that avoid this trap treat job architecture as a foundation, not a reflection. It defines value in a stable way that survives organisational reshaping. It grounds roles in scope, accountability and impact rather than organisational position. 

This creates fairer pay decisions, stronger internal mobility and greater resilience during change. The organisation can evolve without rewriting job value every time it does. 

If job architecture moves every time the org chart moves, then it’s already broken 

• If job architecture shifts every time the operating model is reshaped… 
• If roles are resized because structures change, rather than because the work itself has changed… 
• If pay, progression and equity are determined by organisational design choices rather than role value.... 

The job architecture isn’t providing the stable foundation the organisation needs. It isn’t enabling change, it’s absorbing it. 

In a world of pay transparency and scrutiny, allowing the operational model to dictate job value is a risk organisations can no longer afford to ignore.
