The boundary is not about the size of the company but about the level of repetition and the number of teams interacting with the interface.
If you only have a promotional website and no digital products, that website is sufficient; the digital design system will be redundant and at risk of being neglected. A digital design system is only worth investing in when the same interface components are being recreated by many people and teams in various places. The decision threshold is based on the frequency of repetition and the number of teams, not on brand names or company revenue.
The question Sinh Vũ receives the most is not "what does a digital design system include" but rather "do I need it?" This is the right question, as a digital design system is not something that is better to have more of. If placed incorrectly, it wastes budget, takes up team time, and ends up being neglected.
Do you have more than one digital product (app, platform, internal tool), and do you have more than one team working on the interface?
If the answer is no, then you do not need a digital design system yet. The decision threshold is based on repetition and team size, not revenue or how famous the brand is. A beautifully designed introductory website is just a facade. A digital design system only returns value when used in multiple places; a single facade does not create that multiplication.
Not every system requires enterprise-level polish. A component-based approach is still good for simple sites, but that does not constitute a complete digital design system.

Select a showcase website (P1): You only need a page to present the company, services, and project portfolio. No digital products, no multiple teams building interfaces. This is the right choice for most service businesses, consumer brands, and creative studios in Vietnam today.
Select foundational tokens first: You have one or two small digital products and want to standardize colors, fonts, and spacing before a larger team. This is the most practical entry point when starting to build the system.
Select a complete system: Many products, many teams, with the same interface component being rewritten in multiple places. At this point, the inconsistent costs have exceeded the costs of building and maintaining the system.
Sinh Vũ communicates this boundary clearly with clients from the first consultation. If you only need an introductory page and do not have a digital product yet, we will suggest the P1 website, not the digital design system package. We also decline to build systems when the technical team is too small or the product does not have real users, as the final result will be a beautiful document that no one uses.
When you meet the qualifications, we often recommend starting from the foundational tokens first, standardizing color variables and fonts in the code, and then expanding to the full system according to actual needs. Purchasing the highest level right from the start is often less effective than climbing each level when the organization is truly ready.
In the idea generation or frequent pivot stage, rigid systems can backfire as they slow down progress. It is advisable to start with a lean version once there are signals of product-market fit.

Company size is not a deciding criterion. If you are only operating a promotional website without many products being developed by a large team, then a well-structured website is sufficient. A digital design system only returns value when applied across multiple use cases; a single storefront does not create that multiplication.
Not yet. Brand guidelines are documents for readers, clearly stating colors, fonts, and logo usage. The digital design system is the machine-readable version of the same identity, for the technical team to use directly in code. The two complement each other but do not replace each other.
Sinh Vũ advises against it. At the stage of finding product-market fit, a rigid system can slow you down because every product change necessitates a system change. Focus on the MVP; only when you have genuine user signals should you consider the foundational tokens, and then move on to a full system.
