Technical documentation

---

Developer is responsible to create the technical documentation of the product from both internal and user perspective. Internal documentation are prepared over the course of entire development, while User documentation is created at the end of the User Acceptance testing (UAT) and released along with the Product. 

Product is released in the User environment after successful completion of User Acceptance Testing (Feature alignment with User's need) and User Testing (Validation of the working of each feature). Product Release is different from the Product Launch. 

Product Release: The product is technically complete and ready for customers/users to use.

Product Launch: The company is ready to tell the world about the new product. Product launch is a commercial activity. While it does depend on the new product being ready, it also includes other business operations (for example, training, legal considerations, sales activities).

It is a form of external User Acceptance Testing that involves real users testing a new product in a real environment.   While alpha testing is a thorough and rigorous testing phase, there is no way to test every application of a new product without releasing it to actual users. Beta testing ensures the quality of the product meets users’ standards and expectations through customer validation. There are several ways to release a product in beta to users. Companies can invite users to test the product on their own or they can release it to the public with a disclaimer that it’s still in beta. The product development team goes for changes in the product only if the severity of the issue or risk is very high.  

Gamma testing is the final step of acceptance testing, which confirms that the product is completely ready to roll out at scale in the market. Gamma testing is done with more number of real end-users. The product development team goes for changes in the product only if the severity of the issue or risk is very high. Gamma Testing helps to gain confidence in the product and thereby enables a smooth transition to the market.
