introduction
Introduction
  • The need for process improvement
  • Process improvement methodologies
    • TQM, Lean, CMMI, Six Sigma
the need for process improvement
The Need for Process Improvement
  • Business and technology changes over time and process must reflect those changes
    • Look at the impact of the mobile phone on businesses
  • Companies improve processes to
    • Become more efficient (share data, communicate across the enterprise)
general process improvement 1
General Process Improvement (1)
  • Select the process to be improved
    • Simplify a process for example
  • Define the team that will improve the process
  • Fully define the existing process
    • Reverse engineer the process using a tool such as BPMN
  • Define the simplified process
    • Again, use a modeling tool
general process improvement 2
General Process Improvement (2)
  • Collect baseline data on the existing process
    • Time to execute the process
    • Use this data to judge efficacy of the improved process
  • Assess process stability
    • Does the process have exceptions?
  • Is the process capable
    • Does is meet the objective?
    • Can it be further improved?
general process improvement 3
General Process Improvement (3)
  • If necessary, identify root causes of why a process is not stable and capable
  • Change process redesign as necessary
  • Plan and implement the process change
  • Collect new performance data and compare with baseline data
    • Did the process improve as expected
slide7
CMMI
  • The Capability Maturity Model Integration approach is a way of assessing the strengths and weaknesses of existing processes for the purpose of improving them
  • It’s a set of best practices to improving processes
cmmi process areas
CMMI Process Areas
  • Solutions are organized process areas (types)
    • 16 core processes
    • Processes for acquisition
    • Processes for development
    • Processes for services
cmmi process areas core
CMMI Process Areas (Core)
  • Configuration management
  • Organizational process definition, performance management, training
  • Quality assurance
  • Requirements management
  • Risk management
cmmi process areas acquisition
CMMI Process Areas (Acquisition)
  • Acquisition of hardware, and software
  • Supplier relationships
    • Agreement management
  • Acquisition
    • Technical management
    • Validation
cmmi process areas development
CMMI Process Areas (Development)
  • Product integration
  • Technical solutions
cmmi process areas services
CMMI Process Areas (Services)
  • Incident prevention and resolution
  • Service continuity and delivery
  • Service transition
  • Strategic service management
six sigma introduction
Six Sigma (Introduction)
  • Using standard measurement techniques (statistical techniques) to measure operational performance
    • Adopted by General Electric, Motorola (Engineer Bill Smith was given credit for it)
six sigma terms
Six Sigma (Terms)
  • Define, Measure, Analyze, Improve, Control (DMAIC)
  • Defects per million opportunities (DPMO)
iso 9001
ISO 9001
  • A set of process and quality management standards
iso 9000 principles
ISO 9000 Principles
  • Customer focus
  • Leadership
  • Involvement of people
  • Process approach
  • System approach to management
  • Continual improvement
  • Quantitative (factual) approach to decision making
