7 Service and Quality IT-service : the total management (maintenance and exploitation) of the IT-infrastructure. Products : are developed by the supplier and the customer can’t change much about the quality of the product. De customer judges the product by specific criteria like colours, size etc. (objective) Services : based on interaction with the customer. Services can’t be judged previously, but only when the are provided. The quality of a service is depending on the way the supplier and customer manage their relation. Quality : the level of the service judged by the customer based on demands and expectations. Quality is the fitness for use. Business-IT alignment : matching/adjusting the policy of the IT-service provider to the policy of the customer organisation. Fitness = aptitude 31/03/2017 Copyright DEVOTEAM

IMPROVISATION Unique situations Immediate action “Do something” Trial and error ROUTINE Repetitive Familiar Continuous Automatic PROCESSING Cyclic Structured Especially designed Managed PROJECTS Temporary One time only Defined purpose Dedicated organization Culture : the way of life of a group of people in a organisation, based on behaviours, beliefs, values, and symbols that they accept, generally without thinking about them, and that are passed along by communication. 31/03/2017 Copyright DEVOTEAM

10 Process A process is the execution of all activities, necessary to achieve a predefined result. A process is cyclic, and constantly improving. (Plan, Do, Check, Maintain) A process does not change, unless the mission changes. Activities Measure / Control Standard Policy Output Input 31/03/2017 Copyright DEVOTEAM

11 Management of processes
Where do we want to be? Vision and targets Where are we now? Assessment How can we get where we want to be? Adjust the processes How do we know we have arrived? Metrics

12 Definition of working with processes
Working with processes : the solution to get from a task-oriented (departmental) organization to a comprehensive entity, that combines tasks and aims them at a specified result. A process regulates the transfer of responsibilities, and guarantees progress. 31/03/2017 Copyright DEVOTEAM

13 Advantages of working in processes
Overview of work at hand and status Improved efficiency, higher productivity Result tangible and predictable Knowledge and skills optimally applied Learning curve for organisation Transfer of tasks easier New activities easily adopted Lower impact of human error ....structured quality improvement 31/03/2017 Copyright DEVOTEAM

14 Disadvantages of working in processes
Change from current situation Requires discipline Risk for bureaucracy Overhead during start-up (and process-maintenance) 31/03/2017 Copyright DEVOTEAM

15 In theory there is no difference between theory and practice.
In practice there is always a difference. 31/03/2017 Copyright DEVOTEAM
