We were burned by an offshore team before

Say the word offshore to an American operations director and watch the face. Everybody has the story.

The vendor who agreed to everything in the call. The status reports that were green every single week until the week they were not. The handover that turned out to be a folder of files nobody could run.

It is almost never about skill

That failure is usually not a technical one. The engineers were fine.

It is about distance being managed with optimism instead of with a process. Twelve hours of separation and a weekly call is not a process. It is a hope, and hope degrades quietly: a misunderstanding in week two is not visible until week nine, by which point it is architecture.

What actually prevents it

Four arrangements, agreed before anybody writes code.

A fixed overlap window, staffed. India is nine and a half to ten and a half hours ahead of the East Coast. There is a real window in your afternoon, our late evening. Put it in the plan and staff it, rather than pretending the gap does not exist.

Commits in your own repository, daily. Not a demo on Friday. If the work is not visible every day in a repository on your account, you are not being shown progress, you are being told about it.

Work for hire, your governing law, signed first. The deliverable is working software and its source, not a licence that keeps you paying.

A first project small enough that being wrong is cheap. Four to eight weeks, fixed price, one bounded piece of real work. You learn how a team behaves when something goes wrong, which is the only thing that actually tells you who they are.

The honest part

For West Coast teams the window is tighter, and the honest answer is that more of the coordination has to move into writing. Some teams are good at that and some are not. It is a fair question to ask, and the answer should be specific rather than reassuring.

And if your buyer requires a certified vendor for a particular piece of work, a team that says so is more use to you than one that implies otherwise.

Ask the next team you speak to for daily commits in your repository and a fixed overlap window in writing. The answer will tell you most of what you need to know.
