  • We have four business centers at our facility specializing in application software development We wish to show you two presentations – the first one covers the common basis for all projects undertaken by these business centers The second one looks at one of these departments in more detail – the Online Information Systems BC (it was chosen just as an example)
  • Here’s an outline of what I want to talk about 1 – this section covers our software projects in general 2 – here I’ll tell you what in-house tools and software we use within our development technology 3 – describe how work on projects is organized 4 – the software that we use in everyday work to help us reduce the amount of routine operations
  • 1 – different customers have different needs 2 – but they all want to have the work done as soon as possible 3 – mission critical software is very sensitive to the quality of the implementation the end users’ computer skill level can be very low – so it’s important to have a friendly user interface 4 – for example, many customer’s needs depend upon business needs which change very fast, so the common deadline is “yesterday” 5 – lots of legacy software that needs to be integrated
  • These are the major points that we identified to increase the overall productivity of software teams They also serve as a certain marketing advantage for us and guarantee superior quality of delivered products
  • VisiData is the most successful example of our in-house application framework It provides ready-to-use application functionality 1 2 3 4
  • Now most of the application software projects in our facility are built on top of VisiData. VisiData significantly improves our productivity: At one point approx 60% of the project’s work was system analysis, 30% - testing and deployment and only 10% was actual programming
  • The need for such a tools arise where data from many different sources has to be somehow consolidated So a user can analyze it, store it in a data warehouse or use it in a custom application
  • “ Formalize” here means to clean up the organizational structure and the levels of responsibility So every project member can have a clear vision of his scope of activity and of the actions that he can or can not undertake
  • Every set of tasks is presented by a flow chart To create a flow chart someone has to be a project manager If there’s no flow chart for a certain task – employee don’t have to perform the task And if there’s a flow chart – its implementation is obligatory
  • Earlier, all flow charts used to be just paper sheets It wasn’t very convenient, because they got lost, and the project manager couldn’t control it 100% So the need for automated task-management system arose
  • The main advantage of PSM as compared to paper workflow management is a continuous information flow The message is created for any change event in a flow chart, so the manager and subordinate know about it as soon as possible
