I suggest we need a new tag acceptance-phase/customer-acceptance-phase. There are several questions on the topic of employees (sometimes contractors) completing (or believing they've completed) a (technical) deliverable yet having the customer claim it had missing features/ bugs/ performance issues, demand rework or adding(/removing) features, port it to platform Y, etc. Often unpaid. Often there was no clear written SOW. And/or it was never defined whether the contractor gets paid for any of this, who is responsible for acceptance testing, which specific people at the customer get to define acceptance, how disputes are resolved. It gets even more complicated when there are multiple companies/contractor firms/customers/third-parties/compliance burdens involved.
Notes: No it's not a legal question. The concept is not software specific, it arises in many jobs: engineering, medical, legal etc. It's not always contractors, sometimes it's about managing/dealing with contractors or accepting their deliverable(s), or the wider impact on QA or schedule.
These questions are related, but you can't tell that because the terms used are different every time, and most of the OPs haven't even heard the term "(customer) acceptance phase" or have a clause covering getting paid for it in their contract, "acceptance criteria", Statement-of-Work. Look for "finished", "final", "deliverable", "handoff", "rework" etc.
- What to do when your line manager has a very different vision of the deliverable?
- Customer told me to stay out of discussion regarding status of my delivered product
- Frustration with code supplied by a third-party company
- Manager causing scope creep [closed]
- As a freelancer, what exactly is considered project work?
- acceptance phase, but not about software: Progress blockage due to political tensions
- marginal Product delivered quite rough, and coworker complaining on social network site when in QA
- marginal Colleague keeps on making mistakes, how to help him?
- marginal State in the contract that software developer delivers only binary code not source code? [closed]
- Employer changed duties - possible bait and switch?
- ...many others, please add here...
Note: this tag has nothing whatsoever to do with "job offer acceptance", offer letters, offer deadlines, retractions, recruiters etc., and since those are the more common usage of the term "acceptance" on WP, we probably also need a offer-acceptance to avoid confusion.
