Gantt Charts
Gantt Chart
A graphical depiction of a project schedule. It's is a type of bar chart that shows the start and finish dates of several elements of a project that include resources, milestones, tasks, and dependencies.
task
A job or piece of work that needs to be completed.
milestone
Events that happen; but no time or work is required to accomplish them. They appear in points of major progress in a project and usually refer to the start or end of a major task or group of tasks. Examples include: . The end-date of a project
Step 4 of making a gantt chart
Find critical path
Constraints
Restrictions placed on a certain thing.
Feedback
a response made by a client or worker to the owner of a product or service about its products or services.
Critical task
a task on the critical path
predecessor
a task that needs to be completed before another task can be started on.
Gantt's use
allows managers to monitor the progress off a project
affect of changing the critical path
extends due date of project
software/hardware requirements
the needed hardware for a program or system to work well or at all.
critical path
the sequence of tasks from beginning to end that takes the longest time to complete.
Slack time (lag time)
the amount of time a task can run overtime before it affects other tasks.
lead time
the excess time left when a task is finished earlier than expected.
Ways to obtain feedback
- Questionnaire - Interview - Forums
steps of solving an I.T problem
- identify the possible problem - identify (or implement) backup procedures - identify a likely cause - run diagnostic tests - interpret the results of the test - determine a suitable plan of action - Communicate with the client - implement a solution - implement preventative measures - document findings, actions and outcomes - Communicate with the client
Step 2 of making a gantt chart
Add all task durations
Step 3 of making a gantt chart
Add dependencies (which tasks cannot be start before another task finishes)
Step 1 of making a gantt chart
List all of the tasks in the project
Arrows
Symbol that indicates dependencies
diamond
Symbol that indicates milestones
