Micro-frontend readiness checklist
Micro-frontends succeed or fail on organizational conditions more than on tooling. Use this checklist to see whether your teams, pipelines and product are ready before you commit.
How to use this checklist
Answer each question with yes, partly or no. Be strict: "partly" means it works for some teams or only on paper. The goal is to find the gaps that would make the platform expensive, before the money is spent.
No section needs a perfect result. A "no" in the first two sections is a reason to reconsider the architecture. A "no" in the others is work to plan before or during the first phase.
1. The problem
- Do several teams change the same frontend today?
- Do they regularly block each other with releases, merges or shared code?
- Is the cost of that blocking visible in delays or incidents?
- Have you ruled out simpler fixes, such as better module boundaries or a faster pipeline in the current app?
If there is one team, or teams rarely collide, stop here. See when to use micro-frontends.
2. Product boundaries
- Can you name the business areas of the product and list the routes of each?
- Can a typical feature be delivered inside one area?
- Do areas exchange little data in the browser, with the backend as the source of truth?
- Are there few screens that mix content from several areas?
Blurred boundaries cause the most trouble later. If most features cross areas, the remotes will have to release together.
3. Teams and ownership
- Is each area owned by one stable team?
- Does each team have the skills to build, release and operate its area?
- Is there a person or a team with assigned time for the platform: host, contract, pipeline templates?
- Is there a way to make technical decisions across teams, such as an architecture group that meets regularly?
- Does leadership accept that teams will release without central approval?
More in team ownership and Conway's law.
4. CI/CD maturity
- Is the current frontend deployed by an automated pipeline, with no manual steps?
- Can you deploy on any working day, several times if needed?
- Can you roll back a release in minutes?
- Do automated tests cover the critical flows well enough to release without a manual regression cycle?
- Can your infrastructure host several independently versioned frontends, for example on a CDN or object storage?
If releases are manual and rare today, micro-frontends will multiply that pain by the number of remotes. Fix the pipeline of the monolith first. That work pays off either way.
5. Monitoring
- Do you collect frontend errors from production today?
- Can errors be tagged by area and by version?
- Do you measure real-user performance per route?
- Do alerts reach the team that owns the affected area?
- Is there an agreed process for incidents that cross areas?
Without attribution per remote, every incident starts with a search for the owner.
6. Design system
- Is there a shared component library, or at least shared design tokens?
- Does it have an owner and a release process?
- Can it be consumed as a versioned package?
- Do designers work with the same components the code uses?
A design system can start small. It has to exist before the second remote. See design system across micro-frontends.
7. Technical base
- Is the current frontend on a supported framework version, or is there a plan for the legacy parts?
- Is authentication centralized, so that a host can own the session?
- Can each area reach its backend APIs without one shared frontend backend that all areas change together?
- Have you agreed how many frameworks the platform will allow?
- Is there an owner and a budget for performance?
Reading the result
| Result | What to do |
|---|---|
| A "no" in section 1 | Keep the single application and improve its structure |
| A "no" in section 2 | Work on boundaries inside the monolith first |
| A "no" in section 3 | Solve ownership before technology and name the platform owner |
| Gaps in sections 4 and 5 | Close them in the monolith. They are prerequisites |
| Gaps in sections 6 and 7 | Plan them as part of the first phase |
| Mostly "yes" | Start with a pilot: one host, one remote, one team |
The pilot
Readiness on paper is confirmed with a small real step. Pick one area with a clear boundary and a willing team. Build the minimum platform, extract that area and run it in production. The pilot shows the real cost per remote in your organization and the gaps this checklist missed. The path is described in from frontend monolith to micro-frontends.
A short version for a leadership meeting: several teams that block each other, clear business areas, automated releases with rollback, one owner per area, and someone accountable for the platform. If those five are true, the rest can be built.
