Why do we want to Define Acitivities?
This is necessary for Accurate Estimating. By do so; we can create the wbs which allows us to decompose our entries to the lowest form known as Work Packages.
What is a Schedule Activity?
Is a Deliverable and should not take more than 2-10 days to complete.
What is the INPUTS to Defining Activities
Scope Baseline and Project Methodology
What are the Tools and Techniques used to define Activities?
You need to do Decomposition, Rolling Wave and Templates.
What is the OUTPUT for Define Activities?
You will get a Activities List,Milestone List and Activity Attributes.
What is a Activities List
The Activities list is the output of the Activity definition process that includes all of the Activities to be performed within the project.
Define Milestone?
Milestone is a completion of a phase. The milestone contain dates. There is two types of milestone. One is a Manadatory Milestone which is Government Regulations and Two is Optional which may fall back on Expert Judgement.
What is meant by Activities Attributes?
Activity Attributes Helps with additional planning such as; Risk,resource needs, Activity Identifier,Activity Codes,Leads and Lags,Logical relationships etc.
What is Expert Judgement?
Expert Judgement can come from one of the Project Managers team and is a expert in a specific discipline. They can help with defining,tasks,risks,resource usage,costs etc.
What is meant by the Code of Accounts?
The code of accounts is a hierarchial numbering system for each item in the WBS.
What is meant by Control Accounts?
This is a entry in the WBS that considers the Triple Constraints (Cost,Time & Scope) for that deliverable with in the WBS.
If you measure the Estimated Performance and compare it to the Actual Performance what do you get?
You will get the Over-All performance for the Control Accounts.
What is meant by Project Methodology?
Project Methodology is a method or methods that is used to help with a outcome.
What makes up the Scope Baseline?
You need the Scope Statement,WBS&WBS-Dictionary
What is meant by a Rolling Wave method?
Rolling Wave is a method of decomposing your WBS as far as you can go and then continue in the direction of the WBS. It is used when you do not have enough information.
Why do you want to use Templates? Where do they come from?
You want to use Template so that you expedite breaking your schedule down. You also want to use templates becasue of the important information that exists to help guide. The templates come from Previous projects that are similiar in nature and have been archived.
What is meant by Decomposition Method?
This simply means to break down the scope information so that you may understand the necessary processes to get to a deliverable,product etc. The WBS uses a Decomposition Method. It is the frame work of the project.
When you break down your deliverables, what do you get?
You are down to the level of Schedule Activities. This allows detail which you get from the Schedule Management Plan.
What is the Schedule Management Plan?
This plan is a subsidary plan of the the overall project plan. It is used to control changes to the schedule. This is a formal schedule management plan has procedures that control how changes to the project can be proposed,accounted for and then implemented.
What is meant by Float? How many types are there?
Float is the amount of Time a Task can be delayed w/o delaying the projects completion.
There are 3-types of Floats- Free Float,Total Float and Project Float.
Describe What is meant by a Free Float?
This is Total Time a simple activity can be delayed w/o delaying the early state of any successor activities.
Describe What is meant by Total Float?
This is the Total time an activity can be delayed w/o delaying project completion.
Describe What is meant by Project Float?
This is the total time the project can be delayed w/o passing the customers expected completion date.
Name the 6 Processes in Time Management Knowledge Area
In the planning process you have 5 which are as follows: Activity Definition,Activity Sequencing,Activity Resource Estimate,Activity Duration Estimate and Schedule Development. In the M/C process you have Control Schedule.
Is Time Management a Separate Process from the Management Plan?
No. This is part of our Project Management Plan.
What is meant by Resource Leveling?
Resource Leveling is used when resources are Over-Allocated or Allocated Unevenly. Used mostly to not over/tax the workers on Activities.
What is meant by the Critical Path?
You have Two Kinds of Paths, What are they?
The Critical Path is the longest number of days but yet the earliest time a project may be completed! The two kinds of paths are the forward paths which is the critical calculation of the project and the backwards path which allows you to determine float for each task or deliverable.
When do we stop our decompostion on the WBS?
We stop the decompostion when we arrive at the Work Packages.
Work Packages to complete takes 2-10 days.
What is meant by a Deliverable?
This is the outcome of a project or project phase; a deliverable of a project can be a product or service.
What is Analogous Estimating?
The first one is called the Analogous Estimate. This relies on historical information. Helps predict estimates for the current project. This estimate type is also known as Top Down Estimate and is a form of Expert Judgement.
What is Bottom-Up Estimating?
A technique where an estimate for each component in the WBS is developed and then Totaled up for the over-all project Budget. This is a very long method but very accurate method of estimating.
What is Parametric Estimating?
This is a mathematical model based on known parameters to predict the cost of a project or deliverable. The parameters can vary depending upon the work and materials used. A given example: Concrete/Cost/Cubic yard, Can be how much wood etc. You use this model because Costs change.
The Project Time Performance is shown by what?
What is a Planning Package?
This is a signal that decisions need to be met by a given date. An example is Kitchen is designed but you need the packages to go in. Such as Cabinets,Flooring and Appliances.
Which estimating Technique uses a similar project to predict how long the current project will take to complete?
You use Analogous Estimating.
What is meant by Lag Time?
Lag time is Positive Time added to a task to move it away from the project start date.
Note: Lag is Adding time Between Activities.
What is meant by Lead Time?
This is Negative time added to a task to bring it closer to the project start date.Lead is Subtracting time between Activities.
What system can manage changes to the project schedule?
Schedule Change Control System.
What is meant by Crashing a project!
Crashing means to add resources to the project to compress the the project schedule.
Is Crashing a project costly?
Yes, because you are adding resources to the project which creates an over/all increase in budget.
What is a Activity List?
This is an Output of the activity definition process that includes all of the activities to be performed within the project.
What is Precedence Diagramming?
This is used to sequence tasks in a project. (Activity Sequencing) This is the most common method of arranging the project work visually. The PDM puts the activities in boxes,called nodes and connects the boxes with arrows. Arrows represent the relationship and the dependencies of the work packages.
What is another name for Activity on Node?
Prededence Diagramming Method.
What are activity Attributes used for?
It is used for generating reports. With this info. you could quickly filter the activities to identify the work where a particular vendor is involved.You can use this info. in endless ways to help you communicate infomation to the stakeholders or team.
When you Update the WBS what is another name for it?
They call this Refinements.As the project moves toward completion,refinements ensure that all of the deliverables are accounted for within the WBS.
To update your WBS were would you get the information from?
The Activity List. The List is updated then placed into the WBS.
Activities must be arranged in a logical way, what do we call this?
This is called Sequencing. This helps to identify the Logical relationship between activities, as well as a Preferred relationship between those activities.
There are numerous ways to Sequence the activities, what are they?
Computer Driven- Using computer scheduling programs. Manual Process-Used in smaller projects and preferred in the early stages of the project. An advantage is it's easier to move around dependencies and activities. The last is the Blended Approach- This is a combination of manual and computer.It help's determine the correctness of the activity sequence.
Is is important to have the approach to Activity Sequence with your self?
No,you want to use your project team to help with the Activity Sequencing. This not only gets buy in from the team but also helps with Expert Judgement.
What is the Activity List?
This is the list of actions needed to complete the project deliverables.
Why do we need the Project Scope Statement?
It contains and influences the sequence of events. The statement may include requirements,constraints, and assumptions that will logically affect the planning of activiy sequencing.
Why do we want to incorporate Milestones?
They have to be considered and evaluated when sequencing events to ensure that all of the work needed to reach the milestones is included. It shows a marker to a specific goal or phase.
Why do we want to include Activity Attributes?
Each scheduled activity has attributes that need to be documented. For example, the successor & predecessor of each activity,the lead and lag information, and ther person responsible for completing the activity should all be documented. Very important when it comes to schedule development & project control.
Why do we create Network Diagrams?
So that we may Visualize the work. It shows the relationship of the work activities and how they will progress from start to finish. Another name for Network Diagrams is Acitivity On Node.
If you see Activity on Arrows diagramming methods what is this?
This is a older method of Network Diagramming that is NO longer in use. Can be a trick question on test.
What is Precedence Diagramming Method (PDM).
This is the most common method of arranging the project work visually. PDM puts activities in boxes or circles Called NODES and connects the boxes with arrows.
What does the Arrows represent in the PDM?
The arrows represent the Relationship and the dependencies of the work packages.
Is PDM the most common approach to network diagramming?
Yes, it is used by most PMIS-Software like Project Manager.
There are relationships between activities and 4-kinds. Name them?
Finish to Start(FS), Start to Start(SS), Finish to Finish(FF) and Start to Finish(SF) relationships.
Explain the Finish to Start Relationship?
This means that Task A Must be completed before Task B can begin. The most common relationship. Example: Foundation must be complete prior to framing.
Explain the Start to Start Relationship?
This means that Task A MUST start before Task B can start. This allows both activities to happen in tandem. Example: A painter starts scraping the deck and then the another begins to paint. All of the scraping does not have to be complete to start painting.
Explain the Finish to Finish Relationship?
Means the Task A MUST be completed before Task B is com\pleted. Ideally the 2 tasks should finish at the same time.Example: You have 2 sets of electricians one pulling cable into the house the other connecting into the plates. The activities need to be completed at nearly the same time so the phones are functional.
Explain the Start to Finish Relationship?
This relationship is rarely used. It requires that Task A start so that Task B may finish. An example: Shoes need to be ordered for the store but the construction must be completed first or there is no home for the inventory.
