Defining estimation scenarios
The first stage in the steps to estimating a project was defined to be the definition of the scenarios to be supported in the solution. The scenarios should be defined at as low a level of detail as possible, with the following diagram showing the example scenario definition.

If I consider creative problem solving Iwould usually think about tree hugging, and weird techniques to be at one with the universe. It doesn’t seem to fit well with my idea of IT problems which need engineering solutions. I have, however, found that the use of such techniques will often lead to a better overall solution than simply digging into the technical detail. Read the rest of this entry »

The promise of cloud computing is the ability to scale to meet any demand level almost instantly, saving money along the way by only ever needing the power available that is required now. To do this it uses a combination of virtualisation and grid-based clustering technology. The potential is enormous. To spice it up further then by using a platform such as Gigaspace it is possible to improve performance and scalability to a degree that thousands of transactions a second are possible, based on in-memory database technology.

To be honest, my biggest surprise is that there isn’t something newer in here. They seem to have selected only technologies that are relatively mature, and some of them are what I would consider to be positively mainstream. I suppose that in recommending strategy to major corporate customers they are not going to select technology on the bleeding edge. This selection is more “look what you should have been doing this year” than “get on this band wagon now”.
