Quality Frameworks
  1. Six Sigma
    1. Uses statistics to measure the number of defects
      1. Aims to improve the design of processes in order to reduce number of defects
        1. DMAIC and DMADV are two methods that can be followed to improve current processes in order to reduce number of defects
        2. For a company to declare themselves as being six sigma they must produce no more than 3.4 defects per million
          1. Six sigma is the variation away from the mean which is seen as perfection i.e. no defect produced
          2. Not used as much today
            1. Software processes depend on human behaviour which is not predicatble
              1. Software Characteristics are not easily measured quantitavely
            2. Capability Maturity Model
              1. Used to help refine and develop software processes
                1. Describes a five level evolutionary path that processes go through
                  1. Each level the process become more optimal and organised
                  2. 1. Initial
                    1. 2. Repeatable
                      1. 3. Defined
                        1. 4. Managed
                          1. 5. Optimisation
                            1. Data collected is analysed and improvement is fed back into process
                            2. Processes are measured quantatively
                              1. Therefore success of processes can be predicted quantitavely
                              2. Need process control
                              3. Standard software process is defined and documented
                                1. Successes are consistent
                                2. Need process management
                                  1. Success of processes can be predicted qualitatively
                                  2. Basic project management techniques have been established
                                    1. Need to define a standard process
                                    2. Ad-Hoc
                                      1. Disorganised
                                        1. Project is not managed or documented
                                          1. Need to establish basic management control
