Functional organisational chart: what it is and how to create it step by step

When an SME grows, there comes a point when the “everyone here knows what they have to do” approach stops working. Overlaps start to appear, tasks fall into no-man’s-land, and decisions get stuck because nobody knows who has the final say. A functional organisational chart is the simplest, most visual tool for bringing order: it makes clear what each area does, who reports to whom, and what each person is responsible for. In this article we explain what it is, what it’s for and how to create one in your company step by step.

What is a functional organisational chart?

A functional organisational chart is a graphic representation of a company’s structure organised according to the functions and responsibilities carried out by each department or area, rather than solely according to job titles or individuals. In other words, instead of simply showing “who is in charge of whom”, it focuses on what is done in each part of the organisation and how responsibilities are distributed.

In a functional organisational chart the different blocks are grouped by specialism —production, sales, administration, human resources, marketing, etc.— and arranged hierarchically so that you can understand at a glance how information and the chain of command flow. It’s a clear snapshot of how work is divided and, on top of that, it helps each person understand their role within the wider whole.

What is the purpose of a functional organisational chart?

The main purpose is to bring order and clarity to the internal workings of the company. A good functional organisational chart answers everyday questions that, without it, get resolved through a trail of emails and misunderstandings:

• Who is this task assigned to?
• Who do I report to, and who reports to me?
• Which department takes responsibility for this process?
• Who do I turn to when a problem comes up in a particular area?

By putting the distribution of functions down in writing, the organisation gains efficiency, reduces conflicts over responsibilities and makes it easier to bring new people on board, who understand from day one where they fit in.

Benefits of a functional organisational chart

Beyond having a neat diagram, a well-made functional organisational chart brings very concrete advantages to the day-to-day running of an SME.

It improves communication within the company

When everyone knows what each area does and who to turn to, communication flows far more smoothly. Bottlenecks are avoided, “just in case” emails to half the workforce are reduced, and problems reach the person who can solve them directly.

Greater clarity about each person’s tasks

A functional organisational chart makes clear what is expected of each role. This reduces overlaps (two people doing the same thing) and gaps (tasks that nobody takes ownership of), two of the main sources of internal friction.

Decentralised and specialised decision-making

By assigning responsibilities by function, decisions are made where the knowledge and experience sit. The person in charge of each area can act with autonomy within their remit, without having to escalate everything to management, which speeds up operations.

Greater specialisation in each field

Grouping work by function encourages each team to specialise and improve in its own area. A department focused on its own remit performs better and makes fewer mistakes than one that’s asked to do “a bit of everything”.

Example of a functional organisational chart

Imagine a services-sector SME with around 25 people. A typical functional organisational chart would start from General Management at the top and, below it, group the organisation by function:

• General Management
  • Administration and Finance: accounting, invoicing, treasury.
  • Human Resources: recruitment, payroll, time tracking, training.
  • Sales and Commercial: customer acquisition, commercial support, after-sales.
  • Marketing: communications, social media, lead generation.
  • Operations / Production: delivering the service or manufacturing the product.

Each block would have an area manager, and within each area the specific roles would appear. What matters isn’t the diagram itself, but that it faithfully reflects how work is actually divided in your company.

Difference between a structural and a functional organisational chart

They are two complementary approaches, not mutually exclusive ones:

• The structural organisational chart shows the general hierarchy: the job titles, the levels and the reporting lines. It answers “who is in charge of whom”.
• The functional organisational chart goes a step further and details the specific functions and responsibilities of each area. It answers “what does each part of the organisation do”.

Put another way: the structural chart tells you how the company is put together; the functional chart tells you what each piece is for. Many companies start with the structural chart and then enrich it with the functional one when they need more precision.

Which companies use a functional organisational chart?

A functional organisational chart is useful for practically any organisation, but it’s especially valuable in:

• Growing SMEs, moving from “we all do everything” to needing clearly defined areas.
• Companies with several departments whose functions can overlap.
• Organisations that hire frequently and need new people to understand their role quickly.
• Companies with complex processes where it’s helpful to know exactly who is accountable for each thing.

It isn’t a tool reserved for large corporations: the sooner an SME implements it, the sooner it avoids problems of poor coordination.

How do you create a functional organisational chart? Step by step

Creating a functional organisational chart doesn’t require expensive software or outside consultants. It’s enough to follow an orderly method.

1. Identify the company’s functions. Make a list of all the activities carried out and group them by area or specialism (finance, sales, HR, production, etc.).
2. Define the hierarchy and reporting lines. Establish which areas depend on which and how decision-making flows. Decide who reports to whom.
3. Assign a person in charge of each function. Each block should have a person or role responsible for it. This is where the organisational chart gains real value: concrete names and responsibilities.
4. Represent it visually. Set it out in a clear, simple diagram, from the top (management) down (areas and roles). You can use office software or any diagram editor.
5. Review and update it. The company changes, and the organisational chart must change with it. Review it at least once a year or whenever there are reorganisations, new hires or changes in functions.

Why create a functional organisational chart in your company?

Because order translates into efficiency. A functional organisational chart avoids duplication, clarifies responsibilities, speeds up decisions and makes it easier to bring people on board. It’s a minimal investment of time that saves a lot of misunderstandings and friction over the course of the year.

What’s more, having a clear function-based structure is the first step towards digitalising people management: once you know which departments you have and who’s in them, it becomes much easier to organise time tracking, shifts, holidays or documentation by team.

Is having an organisational chart mandatory in Spain?

No. No Spanish regulation requires companies to have an organisational chart, whether functional or structural. It’s an internal management tool, voluntary, that each company adopts according to its needs.

It’s a different matter that certain legal obligations do require clarity about the workforce’s functions and responsibilities. For example, occupational risk prevention regulations require identifying those responsible for health and safety; data protection requires designating who processes the information; and the mandatory time record (Real Decreto-ley 8/2019) means knowing which people and areas clock in and who supervises that record. In all these cases, a well-defined functional organisational chart makes it easier to comply with what the law requires and to demonstrate who is responsible for each thing.

Conclusion

The functional organisational chart is one of those simple tools that deliver far more than they cost. It brings order to the work, clarifies responsibilities and prepares your company to grow without chaos. Spending an afternoon drawing it up and keeping it up to date is one of the best management decisions an SME can make.

And once you have a clear structure, the natural next step is to take that organisation into practice: managing payroll, clock-ins, absences and documentation in a centralised way and by department. That’s where a tool like LapsoWork saves you hours every month.
