UAT (User Acceptance Testing) gives an organisation the chance to test its software (a new implementation, an upgrade or even a customisation) using both real-world examples and those people who will be using the software day to day. It is often the final stage of the implementation process; conducted to ensure that system requirements meet business needs and allowing for any issues to be fixed before the system goes live.

Unfortunately, UAT is often the part of an implementation project that slips the most, due to lack of resource availability. The end users that are required to do UAT tend to already be stretched to the limit running their organisation and can’t afford the time to test new software. Once the project goes live the issue is exasperated, as the project team typically goes back to their day jobs and contractors are released.  Nevertheless, UAT is vital not only to the successful deployment of any new business application or software enhancement but also to ensuring organisational efficiency and success. It mitigates risk, increases the ROI of the application, and ensures that your organisation’s customers do not wind up being user acceptance testers by default.

User acceptance testing is often considered a one-off at the end of an implementation project. This is where organisations are mistaken. UAT extends beyond your business applications project due to:

1. Additional phases

Your organisation may have chosen to roll out a new business application or upgrade existing software in a phased approach. Phases can consist of different types of users, additional locations, different companies (for mergers, acquisitions, or parent companies) and more. Separate, and additional UAT needs to be planned and conducted for each individual phase. The results need to be communicated as well to ensure that earlier phases benefit from later testing.

2. Hotfixes

Developer testing or bug reporting during normal day-to-day operations may lead to a hotfix. These bug fixes need to be tested by end users to ensure they solve the problems originally reported.

3. Releases or further modifications

Software organisations regularly release updates. Microsoft, for instance, produces General Distribution Releases (GDR) and Limited Distribution Releases (LDR). General distribution releases are usually heavy tested before release whereas limited distribution releases fix issues within a specific problem area. Both, however, need to be tested within your organisation to ensure they fit your real-life scenarios and help you achieve business objectives.

Your organisation may decide to make further modifications or customisations to your business application(s) to help you handle unique business requirements. It is essential that these are tested by end users using the same scenarios and plans to ensure the modifications fit processes and objectives.

4. Upgrades
Dynamic organisations upgrade their software regularly to ensure they are following industry trends, keeping up with the latest technology, and offering their customers the most advanced experience. No matter what upgrade approach
you take (vanilla, with significant customisation, or somewhere in between) it is important that UAT is completed, after a careful review of business requirements. An upgrade is the most important time for end users to ensure that the end result matches the original business requirements.

Where does that leave you? 

It is my recommendation that you have a regular team of end users that spend a part of their day job testing your systems. Whether that is on an ad-hoc basis, weekly, monthly, or based on projects is up to you. It is important to remember that as you evolve as a business your software needs to work for you, and the best way to avoid problems with functionality, automation, corrupt data and more is to have those closest to your business applications monitor and test them.

You might have seen the terms ‘application management’ and ‘IT support’ used interchangeably. We certainly have. But they’re actually two different things and we’ll explain how so in this blog post. Get ready to learn… The definition of IT support The definition of application management How the two compare How to choose the right option for your business
Application management services (AMS) is essentially outsourcing the task of monitoring and maintaining your business applications to an external provider who specialises in these kinds of activities. But why should your business work with an AMS partner? Isn’t it better to manage it all in-house? Let’s discuss… You need specialist knowledge Your IT team is spending more time managing apps than anything else There’s a lot of change in store for the business You want to become more cost-efficient
In 2018, TSB Bank attempted a major cloud migration which failed allegedly because a new data centre hadn’t been tested. This failed migration is said to cost up to £141.6 million ($195m) and then an additional £915m ($1.26bn) to clean up the mess. So, anyone who says cloud migrations aren’t easy is definitely right.
Understanding app dependencies. Assessing whether migrating an on-premises app to the cloud is a feasible option. Actually migrating and managing the environment post-migration. These are just some of the top 10 challenges associated with cloud migration projects. For the most part, it seems a lack of specialist expertise is a key blocker in a successful cloud migration.
In previous blog posts, we’ve discussed the benefits of the cloud and how it compares to on-premises data centres. So, if you’re reading this post, you’re likely to be interested in migrating to the cloud so we won’t bore you with any of the benefits. Instead, you’re probably facing a conundrum - do you handle a cloud migration project in-house or outsource to a partner or consultant?
