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.
![Page 5: SOW / Open Workbench By Wilmer Arellano Summer 2013](https://reader035.vdocuments.us/reader035/viewer/2022062407/56649f485503460f94c6a082/html5/thumbnails/5.jpg)
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
![Page 7: SOW / Open Workbench By Wilmer Arellano Summer 2013](https://reader035.vdocuments.us/reader035/viewer/2022062407/56649f485503460f94c6a082/html5/thumbnails/7.jpg)
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.
![Page 8: SOW / Open Workbench By Wilmer Arellano Summer 2013](https://reader035.vdocuments.us/reader035/viewer/2022062407/56649f485503460f94c6a082/html5/thumbnails/8.jpg)
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
![Page 10: SOW / Open Workbench By Wilmer Arellano Summer 2013](https://reader035.vdocuments.us/reader035/viewer/2022062407/56649f485503460f94c6a082/html5/thumbnails/10.jpg)
Project Timeline/ Parallel task
Two tasks are parallel when they are both dependent on the same task but are independent of each other.
![Page 11: SOW / Open Workbench By Wilmer Arellano Summer 2013](https://reader035.vdocuments.us/reader035/viewer/2022062407/56649f485503460f94c6a082/html5/thumbnails/11.jpg)
Milestones
Examples: • Prototype Implementation.
• Testing.
• Documentation.
• Demonstration.
Each Milestone should be explained with a sentence or two
![Page 12: SOW / Open Workbench By Wilmer Arellano Summer 2013](https://reader035.vdocuments.us/reader035/viewer/2022062407/56649f485503460f94c6a082/html5/thumbnails/12.jpg)
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.

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
