Build it yourself or hire a studio to create a design system
Who builds the system is not as important as who will maintain it after it's done.
Outsourcing is reasonable when you need a proper foundation quickly and the internal team is still small. Building in-house should only be the goal when the team has dedicated personnel mature enough to maintain the system long-term. The most sustainable approach for most businesses today is to outsource the foundation, provide training, and then transfer ownership to the internal team.
- never created a system, needs a proper foundation quickly
- an internal team that is still small or busy running features
- need training and then transfer ownership to internal teams
- has a dedicated team with enough members, the infrastructure is essential for daily operations
A design system is not a project that is completed and then set aside. It is a product that serves all of your other products, and it requires continuous maintenance. Therefore, the right question is not "build in-house or outsource" but rather: after the system is built, who will be responsible for maintaining it?
Three key factors determining the direction
Before making a choice, you need to honestly answer three questions:
- Does the team have enough people? Self-building requires at least one dedicated person who is stable, not just working on it during spare time. If design and technical teams are busy with product features, the system will fail before it can generate benefits.
- Does the team have sufficient foundational knowledge? Building a proper system requires understanding design tokens (variables that store values for colors, spacing, typography) according to DTCG standards. Additionally, knowledge of versioning components (reusable interface elements) and managing changes that break backward compatibility is necessary. Without this foundation, a self-built system often starts off incorrectly and needs to be redone.
- How long do you need the system for? Outsourcing often results in a usable system sooner. Building in-house requires time for the team to learn, experiment, and fix issues before it stabilizes.
When to choose which direction
Hiring an external studio is suitable when the internal team is still small or has never built a system before. It is also appropriate when a proper foundation is needed quickly or when you want to avoid costly mistakes in the foundational phase.
Building in-house is suitable when there is a dedicated team with enough personnel, operating multiple digital products simultaneously. It is also appropriate when the system is a critical infrastructure that needs daily management and cannot be left to external parties for every small change.
Hybrid: outsource to build, then transfer is a common and often sustainable approach. An external party builds the proper foundation, provides training to the internal team simultaneously, and then transfers ownership after a supportive transition phase.
A design system is not a project. It is a product. And like any product, it needs an owner, a roadmap, and long-term resources.

Common mistakes when making a hasty decision
- Building in-house with one or two part-time people: results in a half-baked system, components lack documentation, and it is eventually abandoned. The actual costs are often higher than outsourcing because it requires redoing.
- Hiring without anyone to take over: the system freezes at the final version from the builder, the internal team does not understand the structure, does not dare to modify it, and gradually stops using it.
- Confusing "renting" with "buying outright": Whether renting or building it yourself, the largest costs do not occur during setup but during maintenance. Without budgeting for maintenance, any system will fail.
- Anchor the system to an individual: when that person is away, the entire system loses ownership. Documentation and management processes are the minimum insurance, not a luxury.
The team needs enough people at a minimum level to sustain the system. If there are only people working on it casually when they have time, the system is likely to fail.

Consider two more things before deciding
First, the outsourcing party needs to read the contract carefully: are design files, source code, and documentation included, who owns the rights, and where does the scope of deliverables end? Second, it is advisable to ask from the beginning how the builder will mentor the internal team, as the system truly belongs to the business when the in-house team can modify it themselves.
The advice to consider outsourcing also needs to be read with the awareness that the writer may have vested interests. The honest test is: when the internal team is mature enough and the system is a critical infrastructure that needs daily management, building it in-house is the right choice. With a very small technical team, the straightforward answer is often that it is not yet time to build the entire system. Topic: Building your own design system or hiring a studio.

Frequently asked questions
Once you hire a studio, is the system truly yours?
Legally, this depends on the terms in the contract, so you need to read the ownership and deliverables sections carefully before signing. Actual ownership is another matter: whether the internal team understands and can modify the system themselves. Therefore, the mentoring session and the transition phase are just as important as the contract.
If only one or two people are doing the design, should a design system be created?
It is often not advisable to build the entire system yet. One person working part-time is not enough to maintain the system, and a half-baked system can be more costly than having none at all. With a small team, it is usually best to agree on color tokens and typography first, stop there, and then expand when the team grows larger.
