What are the benefits of user acceptance testing?

• The satisfaction of the clients is increased, as they are more confident that the requirements are met, without the ‘fear’ of how the product will behave in the real environment and if a critical issue will arise when least expected.
• The quality criteria of the product is defined in the early phase of development/implementation
• Vendors have improved communication, both with the clients and inside the team, as the requirements definition is improved through the acceptance tests and signed by the client
• The engineering team ends up minimizing the pressure during the implementation and risks of post-implementation live fixes.
• Stakeholders use the information gathered through UAT to better understand the target audience’s needs

The benefits of UAT significantly outweigh the investments. As the UAT can be planned to spend up to 5-10% of the project time, it can save almost 30% of the total waste. This is a good way for stakeholders to ensure a good ROI out of projects.
