Project management Product development involves:
• many people • many different tasks.
The goals of successful product development are:• high-quality; • low-cost products • efficient use of time,• money, • and other resources.
Project management Project management is the activity of
planning and coordinating resources and tasks to achieve the project goals.
Statement Of Work (SOW) A statement of work (SOW) is a document used in
the Product Development and organizes information about:• Scope of Work (WBS), Describes the work to be done in
detail and specifies the hardware and software involved and the exact nature of the work to be done.
• Location of Work, Describes where the work is to be performed. Specifies location of hardware and software and where people will meet to perform the work.
• Period of Performance, This specifies the allowable time for projects, such as start and finish times.
• Deliverables Schedule, This part list the specific deliverables, describing what and when it is due.
• Who is responsible for what. Similar to an estimate of somebody fixing your roof
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/

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.
Tasks are sometimes specified as activities. They take place over a period of time and generally consume resources.
We prefer tasks specified as deliverables. • http://www.visitask.com/task-g.asp
Work Breakdown Structure (WBS) The WBS may describe:
• the activities of the project or • Activities speak to the work involved in the project,
• or its deliverables. • Deliverables speak to end results.
If activities, then the WBS is expressed by sentences commencing with verbs,
but if deliverables, then the entries are expresses as nouns.
http://www.maxwideman.com/musings/wbswar.htm We will base our WBS on deliverables. Please
make that clear in your WBS
Work Breakdown Structure (WBS) The WBS was initially developed by the U.S. defense
establishment, and it is described in Military Standard as follows: • “A work breakdown structure is a product-oriented family
tree composed of hardware, software, services, data and facilities”
• http://h2o.enr.state.nc.us/bims/WBS/Support_Project_WBS.html
Work Breakdown Structure (WBS)
• This is what we want Deliverables based WBS• http://en.wikipedia.org/wiki/
Work_breakdown_structure#Example_of_a_work_breakdown_structure
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.
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
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.
Project Timeline/ Coupled tasks Coupled tasks are mutually
dependent; each task requires the result of the other tasks in order to be completed. Coupled tasks either must be executed • simultaneously with
continual exchanges of information or
• must he carried out in an iterative fashion.
Milestones
Examples: • Prototype Implementation. • Testing. • Documentation. • Demonstration.
Each Milestone should be explained with a sentence or two
PERT Charts (program evaluation and review technique)
• PERT (program evaluation and review technique) charts explicitly represent both dependencies and timing, in effect combining some of the information contained
in the DSM and Gantt chart.
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.

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 method 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• Antenna Packaging• Antenna Monitoring

Alternate Style (not what we want to use)
This is just an example, you can customize as you like.
In Favorites Gantt Charts, double-click the little square and enter:• A new Phases with:• Name• Category• And ID
Make sure to select phase
The first phase has been created
In Favorites Gantt Charts, double-click the little square and enter:• The Tasks with:• Names• Category• And ID• Duration
• Could leave blank• Probably Better
Make sure to select task
The first task has been entered
This is how it would look after all tasks for the first phase have been entered
To indicate task’s dependencies drag from the end of one task to the beginning of the next one

Project with two phases includedIt is a coincidence that the two phases have same duration
Click to see the PERT
The zoom commands were used to fit the chart in the window
On planning, Resource assignment, double click the little square to enter the resources and their costs
Do the same for non labor resourcesUse Equipment for Space
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 AssignEnter estimated hours in Estimate
As components were entered with a rate of $100, 1.5 will represent $150
The yellow color indicates that the task is low in resources, more hours or space or equipment, etc are needed
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
