Six reasons Goals of the presentation

G1. Show the pros & cons of current typical scopes in process appraisals for the Automotive sector G2. Propose the rationale by SIX (6) reasons for introducing the MAN.6 (Measurement) process G3. Discuss the impacts and possible advantages in the appraisal scope of an organization


Six reasons Agenda

• Introduction– A bit of humour…– ISO/IEC 15504-based appraisal scopes

• The Six (6) reasons1. Measurement is not Project Management!2. Gathering Historical Data3. Optimize the Cost-of-Non-Quality (CONQ)4. Improved the Root-Cause Analysis (RCA) capability5. Goal-oriented Analysis for Process Improvement6. Improving Estimates

• Conclusions & Prospects• Q & A

Introduction ISO/IEC 15504-based appraisal scopes


Introduction ISO/IEC 15504-based appraisal scopes

• Are they the right Are they the right ‘‘process profilesprocess profiles’’ or not? And eventually why?or not? And eventually why?


Six reasons Agenda





Six Reasons 11. Measurement is not Project Mgmt!

• If considering also MAN.6…If considering also MAN.6… Not only time and cost measures (EAV approach), but few more (but focused) measures

in the project historical databases driven by your informative goals


Six Reasons 22. Gathering Historical Data

• If considering also MAN.6…If considering also MAN.6… Stressed more the need for historicize data in the Project Historical Database (PHD) More focused measures will help in reducing the ‘cone of uncertainty’ in estimates


Six Reasons 33. Optimize the Cost-of-Non-Quality (CONQ)

• If considering also MAN.6…If considering also MAN.6… CONQ reduction by a more focused measurement on core elements, also looking to their

cause-effect relationship (e.g. by a BSC-like approach) and more affordable estimates (e.g. Defect and Safety Mgmt from an ISO 26262 perspective)


Six Reasons 44. Improved Root-Cause Analysis capability

• If considering also MAN.6…If considering also MAN.6… Stimulated the refinement of a cause-effect analysis by measures goal-driven, as in a

BSC: needed input also for ISO/TS 16949:2009 §8.4 (Analysis of Data)


Six Reasons 55. Goal-oriented Analysis for Process Improv.

• If considering also MAN.6…If considering also MAN.6… Reinforce process assessment results in multiple PAs and GPs also for mid-term

achievements (e.g. PA 2.2 for more data stored in org PHD and PA 3.1 for better cause-effect analysis based on PHD data)


Six Reasons 66. Improving Estimates

• If considering also MAN.6…If considering also MAN.6… more measures, possibly a higher level of granularity for some of them allowing a

multiple linear regression analysis with lower MREs moving from the same data

Use more independent variablesUse more independent variables• E.g. when using FSM methods, e.g. use combinations of 2+ BFC types

IFPUG BFC (EI, EO, EQ, ILF, EIF) COSMIC BFC (E, X, R, W)

• Results: increased R2 using the same dataset

PreconditionsPreconditions• Historicize project data at the proper level of granularity. E.g.

FSU at the BFC type level (by frequencies and – eventually – weigthed values) Effort at the SLC phase and/or by ReqType and/or… Defects by severity/priority class and/or resolution time by phase, and/or…

• Skill people – not only estimators – a bit more on Statistics• Use something more than averages!


Six reasons Agenda





Six reasons Conclusions && Prospects

• Process Appraisals More process models contains a lot of processes trend to set up a ‘core’ set of basic

processes for appraisals Some proposals in the past, no one including measurement (ORG.5 MAN.6) Appraisals have of course a cost, but how much could it cost more to introduce MAN.6? And

eventually, which could be the ROI from such introduction looking at the possible benefits it could arise to projects?

• Measurement (MAN.6MAN.6) process From our viewpoint, looking at the cause-effect relationship of main process models (e.g. ISO

15504, CMMI, etc.), the measurement process is one of the core set of processes to be taken into account also in a short, quick, reduced-scoped appraisal

Six reasons were shown for introducing MAN.6 in (reduced) appraisal scopes, discussing its impact on appraisal results and corrective/improvement actions to take

Some conclusions... Time and Cost measures cover only two possible perspectives for managing a project from a

Project Management viewpoint, but not from a technical one MAN.6 is the only way to observe – no matter if from an internal or external perspective – the

way a project has been planned to be monitored and controlled during its lifetime We donWe don’’t need too much measures, but few, core ones: t need too much measures, but few, core ones: only applying MAN.6 it’ll be possible to

verify if a project is running the proper level of control for achieving its business goals As a consequence, the introduction of MAN.6 would not seen as an additional cost, but as an

opportunity for organization when appraising their processes

Analyze facts and talk through data(Kaoru Ishiwaka, TQM guru)
