Five good bets to make your project a story of success!

Five good bets to make your project a story of success!
3. First and Foremost: Always remember MURPHY’s Law! (Brooke’s Law: Adding stuff to late to the project just makes it later!) Prof. Dr. Christian Bleis 3 Interaktionskompetenz

An Example (recruitment of a new person to fill a vacant post)
Below is a work breakdown structure for the recruitment of a new person to fill a vacant post. Prof. Dr. Christian Bleis 6 Interaktionskompetenz

So, let‘s build a push bike (and use the WBS)

Start with Bike = 100 units The figure shows a WBS construction technique that demonstrates the 100% Rule and the "progressive elaboration" technique. Level 1 shows 100 units of work as the total scope of a project to design and build a custom bicycle. Prof. Dr. Christian Bleis 10 Interaktionskompetenz

Progressive Elaboration
At Level 2 the 100 units are divided into 7 elements. Prof. Dr. Christian Bleis 12 Interaktionskompetenz
13
Progressive Elaboration
At Level 2 the 100 units are divided into 7 elements. The number of units allocated to each element of work can be based on effort or cost; Prof. Dr. Christian Bleis 13 Interaktionskompetenz
14
Progressive Elaboration
At Level 2 the 100 units are divided into 7 elements. The number of units allocated to each element of work can be based on effort or cost; It is not an estimate of task duration. Prof. Dr. Christian Bleis 14 Interaktionskompetenz
15
Progressive Elaboration
The three largest elements of Level 2 are further subdivided at Level 3. The two largest elements at Level 3 each represent only 17% of the total scope of the project. These larger elements could be further subdivided using the progressive elaboration technique described above. To reduce the complexity and the scope of the tasks Prof. Dr. Christian Bleis 15 Interaktionskompetenz

An Example (recruitment of a new person to fill a vacant post)

Project Tools PERT Prof. Dr. Christian Bleis 17 Interaktionskompetenz

An Example (recruitment of a new person to fill a vacant post)
Below is the PERT chart of the WBS shown above after network analysis has been applied. Prof. Dr. Christian Bleis 18 Interaktionskompetenz

Tasks represented by an arrow ().
PERT-Elements (tasks) Tasks represented by an arrow (). A code and a duration are assigned to each task. However, the length of the arrow is independent of the duration. The PERT method is a technique that allows you to manage the scheduling of a project. The PERT method consists of graphically representing a network of tasks, which, when placed in a chain, can lead to the achievement of the objectives of a project. It was designed by the US navy to allow for coordination of the work of several thousand persons to build missiles with POLARIS nuclear warheads. The PERT method includes the following at the preliminary stage: Precise breakdown of the project into tasks; Estimation of the duration of each task; The appointment of a project manager in charge of assuring monitoring of the project, reporting, if necessary, and making decisions in the event of deviations from projections. Prof. Dr. Christian Bleis 19 Interaktionskompetenz

Stage i.e. the beginning and end of a task.
PERT-Elements (stages, milestones) Stage i.e. the beginning and end of a task. Each task has a start and end stage. (With the exception of the initial and final stages, each end stage is the beginning stage of the next task.) The stages are generally numbered and (normally) represented by a The PERT method is a technique that allows you to manage the scheduling of a project.
