The following page of notes will cover:
- Critical path analysis (CPA)
- Scrum
- Six sigma
Critical path analysis:
The mathematical network analysis technique of planning complex working procedures with refernece to the critical path of each alternative system
- Used for time sensitive manufacturing/products
- Calculates longest path to complete project
- Calculates shortest duration possible if everything runs on time
- Least float (wriggle room) calculated
The process of a critical path analysis:
- Compile a list of all activities
- Work out the length of time for each activity
- Determine the relationship between the activites
- Determine the specific points in time in the deliverable items/activities
Scrum:
A design approach that revolves around teamwork. An emphasis on daily communication and the flexible reassessment of plans that are carried out in short, iterative phases of work.
- Used in project management
- Everyone has clearly defined goals
- Multiple department team (designers, engineers, marketing etc)
- Needs of user/product is at forefront of all decisions
- Agile/flexible/fast moving based on constant feedback
- Led by scrum master
- Timeboxing (allocating and scheduling time to activities)
- Iterative development
- Teamwork is at the centre of the process
Burn down charts:
- Show what still needs completing and helps calculate completion dates
Sprint meeting:
- Daily teem meeting about what's been completed/what will be done today
The three roles in a sprint team are:
- Scrum master
- Product owner
- Developers
Six sigma:
A business management system to:
- Reduce defects
- Increase customer satisfaction
- Increase qualitiy
The 5 stages of six sigma are:
- Define: What does the customer need
- Measure: Measure the processes to determine current performance
- Analyse: Where are the defects/variations
- Improve: What changes need to be introduced to make the system more efficient
- Control: Monitor/record improvements
Reduce process cycle time:
- Reduce non-value added activites (inefficent layout, reducing errors, not completing paperwork that isn't needed)
Reduce pollution:
- Reduce distance materials need to travel, more efficient work that goes to waste, more efficient processes
Reduce costs:
- Reduce process cycle time/pollution, simplifying the steps needed (redesign components), use a common manufacturing process, using standardisation to reduce costs
Increase customer satisfaction - increased profits:
- More satisfied customers lead to increased profit, long service life/high qualitiy leads to customers recommending products which increases profits
