The answer depends on your current resources and scope; there is no significantly better direction.
Doing it yourself wins when the team has skilled designers, the scope is narrow, and you want to retain brand knowledge within the team for the long term. Hiring a studio is suitable when the scope is broad, multiple parties are involved, or the identity system is chaotic and needs an external objective review. If resources allow, a combined approach (studio sets the framework, internal team continues to nurture) often yields the most sustainable results.
Whether to write in-house or hire a studio is a question of resources and scope, not a question of quality. Both approaches can produce good documentation, and both can fail for entirely different reasons. Below are the two approaches, for you to compare with your team's situation before making a decision.
Doing it in-house has an advantage that a studio cannot replace: those involved understand the brand's context deeper than any outsider. You know why the primary color is that color, why the tone needs to sound like this, and what decisions the brand has gone through. This knowledge, if codified by the team members themselves, will stay with the team for a long time.
Doing it yourself is the right choice when:
The studio does not sell prettier designs. The studio sells an external perspective and a process. A lawyer needs to stand far enough away to see the discrepancies that those involved have become accustomed to overlooking. This is the hardest part to do on your own.
In addition to an objective perspective, studios often have ready-made frameworks for writing rules and a library of application templates. Instead of the team having to guess how the rules apply to a real poster, pre-made templates immediately show whether the rules can be applied. This is often the part that is most lacking when doing it in-house.
Hiring a studio is appropriate when:
Many businesses do not fully commit to either side. With a moderate scope, the team has one designer but lacks the time to work from start to finish. A combined approach is suitable in this case: the studio builds the core framework and standard application templates, while the internal team takes over and continues to enhance after delivery.
The condition for a combined approach is that an internal person must participate from the beginning of the project, not just receive the final files. That person needs to understand why the rules are written this way, not just know what the rules are, and must be clearly assigned the authority to stop incorrect versions along with time each week to work on that. Only then can they update correctly as the brand expands after delivery.
Brand guidelines only thrive when someone on the team is responsible for maintaining them. Who creates the initial documents is less important than who manages those documents afterward.

It may be sufficient if the scope is narrow: a few pages of color rules, typography, and proper logo usage. The point to note is that those involved are often accustomed to the discrepancies, making it hard to notice them. If the identity system is still simple and not widely used, doing it in-house remains a reasonable option. Just ensure there is someone leading the effort to completion and not leaving it unfinished midway.
Yes, if delivered correctly: team members participate from the beginning, understand why the rules are written this way, and have time to ask questions when applying them in real work. The long-term maintenance is then your team's responsibility: at least one person needs to be appointed to uphold the standards and be responsible for updates as the brand expands. Without an internal person to take over, any studio's work can easily drift after delivery.
The combined approach is a practical consideration: the studio builds the core framework and a set of standard application templates, while the internal team supplements and expands over time based on that framework. The cost is usually lower than doing everything from start to finish, but the team needs to have a designer with enough capability to continue in the right direction.
