Project management Product development involves:

• many people

• many different tasks. Successful product development projects result in:

• Efficient use of time,

• Monetary savings

• high-quality;

• Saving in other resources.

Project management is the activity of planning and coordinating resources and tasks to achieve the project goals.

Tasks

A piece of work requiring effort, resources and having a concrete outcome (a deliverable).

Although a task may be of any size (a project is a very large task), the term task is usually used to refer a smaller piece of work.

Work Breakdown Structure (WBS) The WBS is the hierarchical list of the project's phases, tasks

and milestones

• Phase: A group of related tasks that completes a major step in a project.

• Task: An activity that has a beginning and an end. Project plans are made up of tasks.

• Milestone: A reference point marking a major event in a project and used to monitor the project's progress.

Scope: The combination of all project goals and tasks, and the work required to accomplish them.

• The scope translates into the timeline and budget. Budget: The estimated cost of a project. http://office.microsoft.com/en-us/assistance/

Phase: A group of related tasks that completes a major step in a project.

Task: An activity that has a beginning and an end. The end is marked by a deliverable

Work Breakdown Structure (WBS)

• The 100% rule– The rule applies at all levels within the hierarchy: the

sum of the work at the “child” level must equal 100% of the work represented by the “parent” and the WBS should not include any work that falls outside the actual scope of the project, that is, it cannot include more than 100% of the work

– The best way to adhere to the 100% Rule is to define WBS elements in terms of deliverables.

Documenting (WBS) Phase 1.1-Antenna Design

• Objective: To produce a 50 Ohm input impedance antenna with a power handling capability of 100 Watts with minimum cost and a minimum power gain of 3 dB

• Approach: Two methods will be used and compared to select the more economical design. Method 1 will consist of the recently acquired Antenna Design Software and method 2 will be based on newly published formulas by A. Jones [4]

• Expected Results: A fully functional transmit antenna with accompanying literature and mounting hardware.

This phase will consist of the following tasks:• Antenna Design• Antenna Construction• Antenna Testing

Remember this is a deliverable based description

Project Timeline/ Sequential Tasks Tasks are sequential when they are dependent on the output

of another task. These because the dependencies impose a sequential order in which the tasks must be completed.

We do not necessarily mean that the later task cannot be started before the earlier one has been completed

Project Timeline/ Parallel task

Two tasks are parallel when they are both dependent on the same task but are independent of each other.

Milestones

Examples: • Prototype Implementation.

• Testing.

• Documentation.

• Demonstration.

Each Milestone should be explained with a sentence or two

PERT Charts / The Critical Path• The dependencies among the tasks in a PERT chart, some of which may be

arranged sequentially and some of which may be arranged in parallel, lead to the concept of a critical path. The critical path is the longest chain of dependent events.

It is a coincidence that the two phases have same duration

On planning, Resource assignment, double click the little square to enter the resources and their costs

Do the same for non labor resources

Use Equipment for Space

Could be the rent for laptop use

You can add the cost of components as “material”

Right click on the tasks and select assignment to assign resources to the tasks

Select Resource and click on Assign

Enter estimated hours in Estimate

As components were entered with a rate of $100, 1.5 will represent $150

If you need to add a new task or phase in between tasks or phases, right click the square and select insert task

There will be a problem if you click schedule again

As the Audio Interface Module and the Mixer Module were using the same resources, they were converted to sequential.

You would need to add more resources to keep the tasks in parallel

The zoom commands were used to fit the chart in the window

•Another Low Frequency Engineer was included

•Two more Lab Spaces were included

•It was not necessary increase the project duration

Click on controlling and then Revise Schedule to see the budget
