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
