Who does what, when and how? With what budget? And what is the best method to get it done?
With bigger projects there are a lot of things to consider, possibly other parties and systems are involved and it's wise to get a clear view of all the conditions before you get started.
A projectplan and experienced projectmanager can help.
Waterval or Agile?
Any method and any tool is as good as who uses it. In general and maybe by definition you are more flexible with the "agile" method but depending on your organisation it might be better to go with the flow downstream. Some things need time to land first before you can continue.
The method to us is subordinate to the goal. We are result-oriented and like to use common sense and good communication to get to the desired results.
A wise person once said:
Don't listen to what people say. Look at what they do.
We are proud of our "track record" of projects that we have realised in time and within budget.
