Project management l l Product development involves: • many people • many different tasks. Successful product development projects result in: • high-quality; • low-cost products • efficient use of time, • money, • and other resources.

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

Statement Of Work (SOW) l A statement of work (SOW) is a document used in the Project Development that 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) l l 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/enus/assistance/HA 011361531033. aspx#Step%201

Work Breakdown Structure (WBS) l The WBS may describe: • the activities of the project or • Activities speak to the work involved in the project, • of its deliverables. • Deliverables speak to end results. l l 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) l 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: //h 2 o. 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_breakd own_structure

Work Breakdown Structure (WBS) l 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

Documenting (WBS) l l l 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 d. B • 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 Remember this is a deliverable based description

Project Timeline/ Sequential Tasks l l 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 l Two tasks are parallel when they are both dependent on the same task but are independent of each other.

Project Timeline/ Coupled tasks l 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 l Examples: l Each Milestone should be explained with a sentence or two • Prototype Implementation. • Testing. • Documentation. • Demonstration.

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.

Alternate Style (not what we want to use) http: //en. wikipedia. org/wiki/Work_breakdown_structure

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

Click here to autoschedule

This is how it would look like Red Color indicates the Critical Path

Project with two phases included It 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 resources Use 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 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 The yellow color indicates that the task is low in resources, more hours or space or equipment, etc are needed

There will be a problem if you click schedule again

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

• 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

Updating The Project Status Set The base Line

Updating The Project Status

Updating The Project Status Double Click on the affected tasks and change the changes in estimated and actual time per Resource

Updating The Project Status The task bar changes colour to reflect status (Red / Blue – Not Started) (Purple – Started) (Grey – Progress completed) The task name changes colour to reflect status (Red – Not Started) (Purple – Started) (Green – Completed)

Updating The Project Status If the task is completed enter 0 in Estimate

Updating The Project Status We reduced 20 hours but because of the weekend it appears to be a longer time

Copy and Paste Table cells can be copied and pasted into excel By the way, this is a representation of the WBS

You can use the information from Openworkbench to build your WBS

The Budget Even the Components are included here
