The Nokia Test (1): Iterations must be timeboxed.How to measure success on agile projects from a cu.Little's Second Law: "People are remarkably good a.Last of all beware all of these "tests" they are not the way the truth and the light, just a lenses to look at your working practices through, none is ever perfect. They need to be enough that the team believes they can deliver the requirement and there are no missing external prerequisites. under cooked and over cooked are equally evil. i have found its the how the requirements are defined that impacts not the degree of detail. Works very well, one last thing the Nokia test implies the requirements are not fully cooked before they enter the team. Scrum Masters focus on the road ahead 2 -3 iterations, PM on the journey as a whole from here to the end. Basically the PM is 80% externally focused and the Scrum Masters 80% internally focused. Having a PM helps allot, they dont get involved in the operational and tactical running of the teams but they do look after organisational issues and dealing with external entities such as 3rd party providers. Its not a competition, its not PM or Scrum Master. I dont understand why so many scrum people have an issue with PMs, the role changes but the role is still valuable. The Nokia test is good but has limitations, I coach teams, scrum masters and PMs. Also, send me an email and I can help a bit more. Go to the Yahoo group scrumdevelopment and ask your question. And we need more truly scientific studies that "prove" that Scrum works. Here, we have many documented case studies, but we need many many more. If your hypothesis is more about Scrum itself, then I can tell you that the overwhelming anecdotal evidence is that it works. In other words: we knew this, the Nokia Test is helping a bit, but we really need a truly scientific (albeit modest) test of the Nokia Test. And, according to Jeff Sutherland, me and others, the lowest are probably getting minimal benefit low to medium, some benefit from Scrum high, often getting great benefits from Scrum. In the form of asking people how well do they comply with it. As to the Nokia Test itself, I think there have been a few unscientific (although probably still reasonably accurate) test of it. Hi JP, You ask a good question.although as a scientist (amateur) I need to clarify your hypothesis. What are your thoughts? Are you aware of similar tests? How does your firm limit Cowboy Agile? Second, Agile/Scrum needs to be adaptive, so having a lengthy test that puts all teams in the same straight-jacket would noticeably limit that adaptability. First, to work with any test, we need the test to be simple enough to be comprehended easily by most of the people involved. Should the test be significantly more detailed? I think not. Is there a better test? Probably we could define one, but let's pass the Nokia Test now. Are the things in the test the most important parts? My thought is that this collection of principles and practices provides a good core of Agile/Scrum that will defend you from the most common dysfunctions. There are many other important parts of Agile or Scrum that it does not cover. So, if you use the Nokia Test, expect to get some resistance. This is true in every firm that I have worked in, I believe. There are some forces in a firm that want to do Cowboy Agile or Agilefall or want Agile to fail ("it's moving my cheese"). (Or did we expect to get out of Fred Brooks' tar pit by doing unprofessional software development?) But a test of this nature is a necessary (if not sufficient) condition to doing professional agile software development. (I will not define right now what 'pass' would require.) Of course they could say "we tried Scrum", but they did not. And pass for a reasonable period of time. Let me say this loud and clear: a firm can't in good faith say "we tried Scrum" and then move away from it if they never had any teams that could pass the Nokia test. I think this is an excellent way to deal with Cowboy Agile or Agilefall.
