Project management systems

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
