Project Management Tools/Diagrams/Charts Flashcards
Work Breakdown Structure (WBS)
- In project management and system engineering, a work breakdown structure (WBS) is a decomposition of a project into smaller components.
- A critical deliverable that organizes the team’s work into manageable sections.
- A plan which expands the project or statement of work into a detailed listing of activities required to complete the project
- Simple, it breakdown complex tasks into smaller activities and then elements until reach a point where it can no longer subdivide the tasks.
Program Evaluation and Review Technique (PERT) Chart
- A tool that shows project as a network diagram
- Event oriented
- Primary purpose is to reduce the time and cost required to complete a project
- Represent events and activities in sequence in the network to determine the critical path
- Used for non-repetitive, unique projects
- Biggest advantage is the critical path analysis help identify the interrelationship between tasks and bottlenecks/issues in the process
Critical Path Method (CPM)
- The longest duration through a project network diagram.
- The shortest time to complete the project considering all dependencies
- Activity oriented
- CPM and PERT are very similar both using overlapping methodologies
- CPM is activity oriented and PERT is event oriented
Gantt Chart
- Graphical representation of the duration of tasks against the progression of time
- Typically outlines all the activities performed in a project in a systematic order to represent critical information and people assigned to each task
- Presents the connection between activities and also the project flow
- Developed in 1910 by Henry Laurence Gantt
- Depicts both state and finish time of each task showing where it is possible to have things happening simultaneously, which helps plan resources appropriately
- Other names: Milestone chart, Project bar chart, and activity chart
Project Documentation
- One of the key aspects of project management
- Document the methods of planning, monitoring, and controlling activities using a manual method like plain paper, colored magnetic markers etc. or using computer-based tools to help organize and summarize the data; the ultimate goal is to complete the project on-time
Milestones
- Important activities in the project which are planned to be completed at an explicit time period.
- Need to review and approved by the stakeholders before it moves onto the next milestone.
- Project leads to prepare the document and needs to share with all stakeholders covering any potential roadblocks or challenges.
Project Report
- Final report which covers project performance, benefits, and also captures lessons learned during the project.
- Help as a guide for future projects better planning and avoid same mistakes
RACI Chart
- Stands for Responsible, Accountable, Consulted, and Informed
- One of the simplest project management tools for planning and communicating the project
- Most common responsibility matrix which maps people and tasks against four profiles in a project
R-Responsible: Performing the task
A-Accountable: Ensuring the task is completed to an acceptable standard aka approve
C-Consulted: Available for help and advice on the task
I-Informed: Wants or needs information about the progress of the task
Process Decision Program Chart (PDPC)
-A type of tree diagram used for the systematic analysis of a process to identify process risks and countermeasures to take to avoid or mitigate those risks.
-Extension to tree diagram and a planning tool to identify risks and countermeasures for bottom-level tasks.
-aka the tool helps anticipate undesirable occurrences and prepare with plans to
neutralize their effect
- Similar to FMEA, both identify risks, consequences of failure, and contingency actions.
- Used when one wants to plan all possible chains of events during a project.
- Used during the decision making especially for new, unique, and complex projects
- Can best handle very difficult and complex problems because of the forced opportunity to create contingency solutions.
Project Plan
- One of the critical phases in project management, comes after the project initiation phase
- Describes the objectives or outputs that are expecting from the project to yield
- Include project scope, strategy, cos-benefit analysis, project scheduling, major milestones, and complete description resources (including human resources) to carry out the project
Pareto Analysis (80:20 rule)
- A way of looking for the most common contributing causes to a situation
- Using a Pareto chart to perform graphical analysis on your data can help you identify the biggest drivers to your process and appropriately prioritize your actions
-Often called the 80-20 rule, 80% of the effects of something can be attributed to 20% of the drivers
Pareto Chart (Pareto Diagram)
-Bar chart that re-orders the categories so they are rank-ordered from largest total
occurrences to the smallest
- In process analysis, this helps identify the most frequently occurring problems or defect – or separate the vital few from the useful many.
- The correct ranking for the Pareto chart categories from left to right would be from highest to lowest.
- Pareto Charts can be easily created by tallying a check sheet and making a bar chart out of it and re-ordering it
When to use Pareto Chart (Pareto Diagram)
- When analyzing the frequency of root cause data and you want to focus on the most significant contributors (the vital few)
- When you want to understand broad cause by looking at the component pieces
- Very effective way to share a lot of information quickly
- Arrange defects from most to least common. See where your biggest issues lie.
Scatter Diagrams
- A graphical technique to analyze the relationship between two variables. Two sets of data are plotted on a graph, with the y-axis being used for the variable to be predicted and the x-axis being used for the variable to make the prediction. The graph will show possible relationships (although two variables might appear to be related, they might not be; those who know most about the variables must make that evaluation). One of the “seven tools of quality” (see listing).
- Study the possible relationship between two variables. Chart interactions of the two variables.
Seven tools of quality
- Tools that help organizations under their processes and improve them. The tools are:
1. cause and effect diagram
2. check sheet
3. control chart
4. flowchart
5. histogram
6. Pareto chart
7. scatter diagram
Control Chart
Study variation over a length of time. Or in other words, look at the changes in a process over a certain period.
Histogram
Also known as a frequency distribution. That’s because the height of each bar represents the frequency of occurrence.
Cause and Effect Matrix
aka
X-Y Diagram
aka
Correlation Matrix
Cause and effect matrix is a six sigma tool uses to prioritize the key process input variables (KPIVs) based on priorities of customer outputs (KPOVs). In other words it establish the correlation between process input variables to the customer’s outputs duringroot cause analysis.
- Objective is to mathematically compute the correlation between Key Process Input Variables (X’s) and Customer outputs (Y’s).
- A cause-and-effect matrix can be used to evaluate and document relationships between input and output variables. This method is also very much similar to theQuality Function Deployment. It objectively evaluates the team’s subjective opinion about the KPIVs.
When Would You Use an X-Y Diagram in the DMAIC Process?
- Great tool for prioritizing a long list of possible things and especially uses in the Measure phase of DMAIC
- This method also used to determine the primary factors for experiments in DOR and also to determine the objective of the Matrix Diagram and FMEA
- In a process all the input variables might influence the outcome, but all the input variables are not equally important. Hence develop a mathematical model to concentrate the important input variables with respect to the customers output. Cause and effect matrix helps to identify such key input variables.
How to use X-Y Diagram?
Steps:
- First identify the customer requirements or in other words understand the voice of customer. This can be collected by conducting surveys, focus groups and other means to collect their priorities. Place those priorities in at the top of the X-Y diagram
- Assign priority factor for each of the customer outputs. Generally use 1-20 scale, where 1 being the low priority and 10 being the high priority to the customer
- List all possible key input variables or the improvement factors of the process in each row, those are the X’s in the X-Y Diagram
- Assess the relationship between key input variables to the customer outputs and rank each input variables accordingly. Recommended to use geometric progression scale (0,1,3,9)
- 0: no impact, 1-low impact, 3-medium impact, 9-input has strong impact or correlation on output - Cross multiply the customer output priority numbers with correlation rankings and sum each row at extreme right column
- Finally, determine the rank based on the highest sum total and highlight the critical few variables. This will help to identify improvement areas.
Casual Theory y=f(x)
Things to Remember
- A problem with your output (y) has two potential sources: your input (x) and your procedure (f).
- These two potential sources are not exclusive. You could have an issue with both your input (x) and your procedure (f).
- Most processes are complex enough that you’ll need to break them down into multiple sub-processes, each with their own input and procedure.
- Prioritize your problem outputs. In other words: focus on the larger problems first. You can fine-tune later.
- Problems in a sub-process can be replicated and enlarged as its output moves through subsequent sub-processes. Ensure that you drill down to the ultimate source of the issue.
Casual Theory y=f(x)
Causal theory, in Six Sigma terms, means that you create output (y) from an input (x) and a function (f).
It’s made up of three components:
- y: What you get out of a process. In a manufacturing context, this is a physical product.
- x: What you put into a process. In the same manufacturing context, this is a material or part.
- f: What you do to turn x into y. In manufacturing, this is a machining or assembly procedure.
y = f(x) Output = method * input
Using Causal Theory in Six Sigma
When you have a problem with your output (y), causal theory tells you that there are two possible culprits:
-
f: Your procedure for creating that output.
- x: The materials or information you’re adding to that procedure.
Correlation
-A relationship between two events. They occurred at much the same time, in same population, or in the same circumstances.
Example: spilling a glass of milk and dropping an egg. They might occur at the same time, and they might have the same cause, clumsiness or a fright. But one would rarely cause the other to happen
