Hoofdstuk 2 - Project Management Flashcards
Name the 5 activities covered by project management
Planning, monitoring, organization, staffing and directing.
What is a milestone? What can you use them for?
◦ A verifiable goal that must be met after task completion.
◦ It can be used to monitor the progress of the project.
What is a critical path? Why is it important to know the critical path?
◦ It is the longest path in the activity graph.
◦ It is critical because a delay in this path causes a delay in the entire project. The treatment of this path, determines the outcome of the project.
What can you do yo recover from delays on the critical path?
◦ We can crash the schedule by adding resources to critical path activities to shorten the duration.
◦ Another option is to place sequential activities in parallel for all or part of their duration.
How can you use Gantt charts to optimize the allocation of resources to a project?
◦ A Gantt chart shows how the resources are allocated when we choose to schedule tasks at the earliest start date. Typically this will give an uneven resource distribution.
◦ To optimize resources we need to reshuffle our tasks so that the resources are distributed evenly. This may require to extend the termination date or to split tasks.
◦ Gantt charts are a representation of the task in means of time and needed resources.
What is a “known known”, a “unknown known” and an “unknown unknown”?
◦ A known known is a thing you know you know
◦ An unknown known is a thing you know you don’t know.
◦ And lastly, the unknown unknowns are the things you do not know you don’t know
How do you use PERT to calculate the risk of delays to a project?
◦ First, you can use PERT to find the critical path. This is a path where one delay, sets back the entire project thus with a high risk of hindrance.
◦ It also shows task dependencies. This can also be used in our risk assessment because if one task cannot start before the other is completed, we know a delay can happen if the first has a set back.
Why does replacing a person imply a negative productivity?
Because the new person has to start from zero intelligence of the project. The new person first need to adapt to the project before he or she can work normally
What’s the difference between the 0/100, the 50/50 and the milestone technique for calculating the earned value?
◦ With the 0/100 technique, we get 0% when task not complete and 100% when the task is completed. Here, tasks should be rather small.
◦ With the 50/50 technique, we already get 50% of the earned value when the task is started and 100% when the task is completed. Here, tasks should be rather large.
◦ The milestone technique: our earned value equals the number of completed milestones divided by the total number of milestones. This is a good technique for summary views on large schedules.
Why shouldn’t managers take on tasks in the critical path?
Because managers should trust their people and manage! They must delegate.
What is the “definition of done” in a scrum project?
It is a checklist of the types of work that the teams is expected to successfully complete before it can declare its work to be potentially shippable.
Give a definition for a Squad, Tribe, Chapter and Guild in the Spotify scrum model.
◦ A squad is a scrum team
◦ a tribe consists of loosely coupled scrum teams working on related features/components
◦ A chapter are team members with similar expertise within a tribe
◦ A guild = team members with similar interests across tribes
