Yes, thank you Shane. I’ve been in the technology area for about 30 years now, helping software development teams and organizations deliver technology; started out as a developer, worked my way up in sort of project management roles and over the last 15 years I have been involved in enterprise transformation and standards development and work like that. A couple of big things where I worked with Microsoft and their services oriented architecture group establishing their business architecture practice, so I was a significant contributor to their whole model and the business capability work and stuff that you are familiar with that we’ve done there.
We have a Harvard Business Review article where we talk about some case studies where we made some transformational change in organizations with that. I’ve also worked with PMI on the standards side, I helped deliver the OPM3 2nd edition standard; one of the important contributions there was bringing in the organization enablement aspects - really how do you sustain these changes over time and helping really focus on outcomes and maturing, situations where we’re maturing project management over time and for the last couple of years I’ve been working with the IIBA and you on the business analysis extension, the Agile extension to the Business Analysis Body of Knowledge. During the time I also run a consultancy where we go and we actually work with organizations and help them implement these practices and make this type of changes.
And so what we are trying to do is come up with a cross cutting set that clearly defines kind of what Agile is and why this is really important is the HR director sitting in their office in an enterprise and is trying to help their organization position for this transformational way to deliver software, has no framework of understanding of what the skills and knowledge and competences are that these people have to have. So by defining this set of learning objectives and making it understood how they fit together and how they are valuable in different circumstances, we are going to help enterprises make better decisions about the types of skills that people need to have, driving a career paths, driving training and driving the hiring practices to make sure you are getting the right people. So the ICAgile is really important in the regard that they are not trying to sell training, they are trying to build a context of understanding that can be consumed outside of the Agile community.
This is a really nice piece of work that this team is collaboratively put together in this space and hopefully it’s going to get a ton of traction in the industry.
Maybe we can put a link on the InfoQ site; that would be awesome.
So there is an aspect of this that really becomes part of the same job that’s quality, and it’s not necessarily on the load testing, some of the big things, they are certainly big parts of QA or testing they are distinct, but this sort of managing at the business value level across multiple Agile teams or across the single Agile team. This distinction isn’t meaningful between project management, business analysis and testing all the time. So this value management is that layer of pulling it all together. And another thing is you and I in the business analysis community; you understand that what I am calling value management is what you and I always done as business analysts.
Chris Matts will say the same thing. He does the same job in every project and he gets hired into different roles. We’ve had this conversation for a long time, but to get the world to understand that we are talking about something other than the order taker who takes pieces of paper from the right side of the desk and slides it across the left side of the desk. It’s sort adding a term that probably describes it better because a business analyst analyses something and produces an analysis. So defining and adding a new language isn’t overloaded with the history of bad business analysis ispart of what this value management is about.
So two interesting things happened: we tend in projects (because of how we’ve been managed over time) to push those riskiest things out to the end because they are the things that make it hard to keep our earn value on track or to keep our release burn down matching to what the expectation of the business is, but they are also the ones that are most likely to cause us fail on the commitment, so we tend to push them out to the very end and then we don’t fail until we’re 80-90% of the way through the project when we start doing the risky things. The concept here is doing good risk analysis and using risk above new value as a prioritization mechanism as trying to get explicit thinking around that in the enterprise.

A common “best practice” for unit tests is to only write a one assertion in each test. I intend to question this advice by showing that multiple assertions per test are both necessary and beneficial.
