One of the perks I’ve enjoyed about being a consultant is that I’ve been able to work in a number of different organisations in a range of roles. I’ve had the pleasure of working in some very small private companies to massive companies with offices around the world, as well as a number of public and government organisations, again both large and small. One would think that each of these different environments would have their own unique challenges, and they do to a certain degree, but you’d be surprised how many things are exactly the same across the board.
- Customer satisfaction by early and continuous delivery of valuable software
- Welcome changing requirements, even in late development
- Deliver working software frequently (weeks rather than months)
- Close, daily cooperation between business people and developers
- Projects are built around motivated individuals, who should be trusted
- Face-to-face conversation is the best form of communication (co-location)

- Best architectures, requirements, and designs emerge from self-organising teams
- Regularly, the team reflects on how to become more effective, and adjusts accordingly
It’s interesting that despite the first principle being; ‘Customer satisfaction by early and continuous delivery of valuable software.’ UAT, as we have traditionally known it, doesn’t fit well into an Agile delivery model. Many Agile teams dispense with UAT and rely more heavily on the Show and Tell session to get customer sign off. In Scrum, this is done in the Sprint Review Meeting and involves a demonstration of the user stories that have been delivered (according to the Definition of Done) in the sprint. One of the objectives is to elicit stakeholder feedback.This is good practice, fosters collaboration and creates a high level of discipline while also meeting the objectives of the first principle. Product demonstrations should be interactive so that stakeholders have the chance to provide feedback however, I often wonder “Is this enough?”. Participants in the ‘Show and Tell’ and the Sprint Review Meeting should include, amongst others, the Product Owner, Stakeholder and Sponsors and Customers. However, in practise, I tend to find two problems;
If we were to visit the town where I grew up, I could take you to any place in that town without having to use Sat Nav. I wouldn’t even have to glance at Google Maps to find my way.
