Skills mapping: definition, 5-step method and example

What is skills mapping?

Skills mapping answers a simple question: which skills does the organisation have today, where are they, and where are they missing compared with its needs? It is built by occupation, team or site, and covers technical, behavioural and cross-cutting skills (digital tools, languages, use of AI).

It is only valuable if it leads to a decision. A map that remains a file opened once a year describes a situation that has already changed; a map linked to the skills development plan becomes a management tool.

Skills map, competency framework, skills matrix: what is the difference?

The three terms are often confused, yet they refer to three distinct and complementary objects.

Tool	What it describes	Question it answers
Competency framework	The skills expected for a job, with their criteria	What must people be able to do?
Skills matrix	Each team member's level on each skill, in a table	Who can do what, at what level?
Skills map	The consolidated, organisation-wide view, with gaps and risks	Where are the gaps that matter, and what should we do?

The framework defines the target, the matrix measures the current state team by team, and the map aggregates and interprets. In the French Labour Code, the competency framework of a vocational certification is defined as the document that identifies the skills and knowledge, including cross-cutting ones, that follow from the activities (Article L6113-1). This vocabulary is useful in companies, even outside certification.

A 5-step method

1. Set the scope and the objective.
Choose a pilot scope (one occupation, one department) and a specific use: preparing the skills development plan, anticipating a retirement, supporting a change of tool. A vague objective produces an exhaustive and unusable map.

2. Build the competency framework for the jobs concerned.
For each job, list 8 to 15 observable skills and the required level. There is no need to start from scratch: France Travail's ROME 4.0 (the French public employment service's occupational directory) describes 1,911 occupation sheets with their know-how, knowledge and soft skills under an open licence, and the European ESCO classification lists 3,039 occupations and 13,939 skills and competences, free to consult.

3. Assess actual levels.
Combine several sources: self-assessment, the manager's appraisal, and above all objective evidence (work simulations, assessment results, certifications obtained). A shared scale defined in writing, for example from 0 to 4, prevents each manager from rating according to their own interpretation.

4. Consolidate and analyse the gaps.
Gather the assessments in a matrix, then look for three kinds of signals: gaps between required and actual levels, critical skills held by only one or two people (dependency risk), and skills that exist but are unused, which are useful for internal mobility.

5. Decide on actions and plan updates.
Each significant gap gets a response: targeted training, mentoring, mobility, recruitment or acceptance of the risk. Set the update frequency and the source of new data from the outset; ideally, training assessment results feed the map directly.

Example of a skills map (fictitious)

The following example is fictitious and for illustration only. It covers an 8-person accounting department, on a scale from 0 (not acquired) to 4 (expert, able to train others).

Skill	Required level	People at required level	Gap	Criticality	Chosen action
Month-end close	3	6 of 8	2 people	High	Internal mentoring over two closes
E-invoicing	3	2 of 8	6 people	High	Group training before the deadline
Consolidation	3	1 of 8	Dependency on one person	High	Handover pairing and documentation
Advanced spreadsheets	2	7 of 8	1 person	Medium	Individual online module
Using an AI assistant for analysis	2	3 of 8	5 people	Medium	Hands-on workshop and usage rules

The useful reading is not the department average but the high-criticality rows: here, consolidation relies on a single person and e-invoicing is poorly covered. These are the two priorities of the action plan.

How does it relate to GEPP and the skills development plan?

Skills mapping is the factual basis of GEPP (strategic workforce and career-path planning, as it is called in France). In France, companies and groups with at least 300 employees must negotiate on GEPP, and Article L2242-20 of the Labour Code includes in that negotiation the three-year training orientations and the objectives of the skills development plan. Without a map, these orientations rest on impressions. The map also feeds professional reviews and skills-based recruitment.

What are the common mistakes?

• Too many skills. A framework with 60 lines per job will never be assessed seriously. Better to have few, well-described skills.
• An undefined scale. "Level 3" must correspond to observable behaviour, identical for all assessors.
• Self-reporting only. Self-assessment is useful to open a conversation, insufficient to make decisions. See measuring skills acquisition, beyond completion rate.
• A frozen snapshot. Without a source of updates, the map loses its value as soon as teams change.
• Forgetting employee representation and personal data rules. In France, the works council (CSE) must be informed before automated personnel management systems are introduced (Article L2312-38 of the Labour Code), and individual skill levels are personal data subject to the GDPR.
