The Dark Side of Scrum?

In the last week I've seen a couple of blog posts that bemoan a codification of agile software development into rigid project management frameworks.  Both are interesting and caused me to reflect on our own adoption of agile - because to a fair extent we are doing exactly what these posts criticise.

The first such post is titled The Dark Side of Scrum.   Thomas Scranz asks why, if the first principle of the agile manifesto is that we value individuals and interactions over processes and tools, have people adopted Scrum as a dogmatic codified interpretation of agile?  I will note my thoughts in this post. (I hould clarify that we're not following Scrum per se; our process started nearer XP and has adopted some notions from Scrum and DSDM along the way).

Thomas first argues that with continuous integration and automated testing tools, we can move beyond fixed two-week time boxes to a faster and more flexible delivery cycle.  Well, that may be true for an organisation where agile is more ingrained and understood, but for us the two-week iterations are already a tremendous improvement on what went before and we still have quite a bit of work to bring these ideas to more of our projects.  The fixed development cycles are also very useful in explaining agile to our business partners.  The structure of this codified approach gives our partners and user groups a clear schedule for interacting with the projects. So while Thomas may well be right for his firm, that more flexible approach is not for us just yet.

Thomas's next beef is with the notion of the product backlog.  He argues that specifying and estimating everything up front is time consuming and prone to change as the project develops.  This is an area where I have some agreement.  Many agile advocates seem to want two incompatible things:
  1. A complete list of estimated stories so that you can measure progress towards the goal, and
  2. Freedom to add new stories and re-estimate throughout the project.
If Thomas had focussed on this aspect, I think I could have agreed with him. Instead, he described his experience that a product backlog tends to be a wishlist of everything and that the individual items tend to be feature requests rather than expressions of what the user will be able to achieve with the product.  Our experience so far is rather different.  Our old waterfall "business requirements documents" had exactly those flaws - they tended to be long lists of all the features that the customers could think of, with little or no relation to how people would use the system.  User stories have given us a large step forwards, both in describing what users want to achieve and in helping them prioritise the things that are really important.

The third point from Thomas's article was that Scrum stand-ups can create an interrogation atmosphere, because they focus on what each person did yesterday and will do today.  He suggests instead to focus on the progress of each user story rather than on each team member.  This seems a potentially good idea, provided that everyone leaves the stand up knowing what they need to do next and what the rest of the team expect of them.  As I'm not involved in projects at that level, I'd be interested to hear which approach works best for our project teams.

Webinar: Powering your business with Cloud Computing

On October 14th, I will be hosting a Grid Computing Now! web seminar on the topic of Cloud Computing. We have lined up two very interesting speakers who are using Cloud now to make businesses work. Ross Cooney had a good technological solution to sell but couldn't make it economic until Cloud Computing allowed him to pay for his computation only when he needed it. He will discuss the instant benefits and long term impact of cloud computing to the development, competitiveness and scalability of your application. Alan Williamson created the BlueDragon Java CFML runtime engine that powers MySpace.com. He advises several businesses and will give an overview of the different types of services available and how to avoid being locked-in to a single supplier. You can register for this event here .

Business Model Canvas

A Business Model Canvas is a tool for mapping the core functions and capabilities of an organisation.  Compared to the Core Diagrams that I described in an earlier post , the business model canvas attempts to present more aspects of the business, starting with the value proposition – a statement of what the organisation offers to its users (in the business world, to its customers).  It shows the activities and resources, as Core Diagrams do, but also shows user relationships & channels, and also benefits and costs.  I’m not aware of any universities that have used this tool but you can find examples from elsewhere on the web. We are considering business model canvases as a tool for mapping the strategic capabilities of units at the University of Edinburgh.  Phil Taylor, our EA contractor, sketched an outline of what a business model canvas might begin to look like for HR: This is only intended to be suggestive: the real canvas would need to result from in-de...

Changing Principles

In EA, architecture principles set a framework for making architectural decisions.  They help to establish a common understanding across different groups of stakeholders, and provide guidance for portfolios and projects.  Michael Durso of the LSE gave a good introduction to the idea in a webinar last week for the UCISA EA community. Many organisations take the TOGAF architecture principles as a starting point.  These are based on the four architectural domains of TOGAF: business, information/data, applications, technology/infrastructure.  These principles tend to describe what should be done, e.g. re-use applications, buy in software rather than build it, keep data secure.  See for example the principles adopted at Plymouth University and the University of Birmingham . Recently though, I encountered a different way of looking at principles.  The user experience design community tend to focus more on how we should do things.  E.g. we should...
