alpha

In simple English

In tech companies, alpha is a critical phase in the product development lifecycle. During alpha, developers test the software's core functionality, identify bugs, and fix major issues before the product moves to beta testing with external users. The alpha phase is typically closed and internal, meaning only the company and its team members have access to test the software. This phase helps ensure that the product works as intended and meets the requirements specified during planning. Teams often run alpha tests on different devices, operating systems, and use cases to catch as many problems as possible early. After alpha is complete and the product is stable enough, it moves to beta, where external testers or limited users can try the software and provide feedback.

Say it like this

✓We are launching alpha next month
✓The alpha phase is taking longer than expected
✓This feature is still in alpha

Real examples

in a standup

"The payment system is in alpha right now, so we are still working out the bugs before we send it to beta testers."

in a code review

"We should not merge this into alpha until all the critical bugs are fixed."

in a team meeting

"Alpha testing starts next week, so everyone needs to prepare their test cases by Friday."

Don't say this

Handle with care. Alpha refers to an early testing phase, not the first letter of the Greek alphabet in tech context. Do not confuse with beta (next phase) or MVP (minimum viable product).

✕We are ready to alpha the product to customers.
✓We are ready to move the product from alpha to beta testing with external users.— Alpha is an internal phase, not something you release to customers. You move from alpha to beta, where external testing begins.
✕The alpha version is perfect and ready for production.
✓The alpha version is stable enough to move to beta testing.— Alpha is not the final version. After alpha comes beta and then the production release. Alpha is still an early development phase.
✕We skipped alpha and went straight to release.
✓We skipped alpha and went straight to beta testing.— The normal process is alpha, then beta, then release. If you skip a phase, you would skip from alpha to beta, not to release.
