Clarification on Configuration Management


This is the response to AKM Desai’s posting of March 31.

Since you say that this old project is nearing its completion, I presume that it must be having some level of control on its work products, and that practice has allowed it to reach its final stages. All the intermediate deliverables, software code, executable files and so on must have evolved in some manner and the project team must be having a system to establish and maintain its work in a defined, and planned fashion. If that is true, CM is being applied to this project. Generally speaking, project management should decide which work products should be subjected to CM and the extent of control on them.

Having said that, there may be a good reason for the project to use a suitable CM Tool for maintaining the integrity of its work products by using a CM Tool. The selected tool will mitigate the increasing risk of project loosing its work products in its final phase and increase the success rate by providing only the desired versions of intermediate work products for final product build. However, if I were the management, I would have left the decision to the Project Manager.

In any case, just bringing in the CM Tool for satisfying the appraisal team is not recommended. CMMI or other quality frameworks don’t impose the use of a CM Tool. Project Management has to take a call. If the PM is satisfied and has good reasons for not using a tool, it should be acceptable to the appraisal team. Anything important enough to maintain its integrity must be subjected to CM practices.

People feel Agile is some rocket science which does not need processes. Totally false. A formal CM in agile environment is much more important to support frequent changes the agile project undergoes. So if the project in question is an agile project, a CM Tool should have been  necessary for it.

QA Team Size


Let me try to respond to Rohit’s posting of March 31 regarding available benchmarks on QA Team size in software industry.

Famous benchmarking expert Capers Jones, in his presentation ‘SOFTWARE QUALITY IN 2002: A SURVEY OF THE STATE OF THE ART’ indicated that software organizations on an average need more than 5% of total manpower in quality for ‘Active QA’, less than 3% for ‘Passive QA’ and less than 1% for ‘Token QA’. This data is based on a survey of 600 organizations (150 Fortune 500 ones) and 30 Government or military groups. For smaller organizations, the percentages will be same or slightly higher.

With added process orientation based on CMMI, availability of best practices and latest benchmarks from ISBSG, SPINs and SEIR and availability of automated tools for project management, metrics based SPI and knowledge management, certain organizations may be able to bring down these percentages in case they peruse real quality and don’t run after certifications.

3 to 5% of engineering team size in QA is a good benchmarks in 2011.

I feel,  software industry still has plenty of  improvement opportunities in metrics based SPI. If implemented correctly and linked to business benefits (not certifications), this percentage may further come down.

Members may contribute their comments on this issue.

Differences / salient features of CMMi v1.3 over v1.2


I have tried to respond to Rohit’s post of 23rd March regarding ‘Differences / salient features of CMMi v1.3 over v1.2’ after going through the new version of CMMI-Dev (V 1.3) and have listed down following changes in it:

 

Architecture related changes:

  1. ‘Typical work products’ referred in CMMI-Dev, V 1.2 will be are now called ‘example work products.
  2. ‘Amplification’ model component has been removed, making the model simpler.
  3. ‘IPPD’ addition has been removed from V 1.3. You don’t see the term ‘IPPD’ anywhere in the model.

Process Area category:

  1. REQM PA has been moved from Engineering category to Project Management category.

New areas included in PA descriptions while providing interpretation of SPs and GPs:

  1. Agile methods
  2. Quality attributes (i.e., non functional requirements or “ilities”)
  3. Allocation of product capabilities to release increments.
  4. Product lines
  5. System of systems
  6. Architecture-centric development practices
  7. Technology maturation
  8. Customer satisfaction

The new model is therefore easier to implement by a variety of  organizations in software, as well as other industries.

GGs, GPs, and GP Elaborations:

  1. Generic goals, generic practices, and GP elaborations are available at one Place in the first section of Part 2. The GP elaborations in the process areas have been removed.
  2. Simplified GG1 to make it more understandable.
  3. Renamed GP 2.6 as ‘Control Work Products’ (earlier it was ‘Manage configurations’).
  4. GP 2.9 is now ‘Objectively evaluate adherence of selected work products’. ‘Selected work products’ now provide more flexibility.
  5. Simplified the GP 3.2. Earlier statement ‘Collect work products, measures, measurement results, and improvement information’ is now replaced with ‘Collect process-related experiences’.
  6. GG4 and GG5 have been eliminated.

High Maturity Updates:

  1. The possibility of subjective interpretations of high maturity PAs has now been minimized by adding clarifications on:
  2. Process models and process modeling.
  3. How business objectives thread to high maturity.
  4. Common causes – definition/concentration/expectations at ML5.
  5. Defining high maturity expectations on individual PA performance.
  6. High maturity re-structuring (including stronger alignment of ML4 & ML5).
  7. Sub-process – selection/definition/level of instantiation is better explained now.
    1. Better explanation of high maturity requirements and expectations eliminates subjectivity in interpreting the goals and practices. Such subjectivity was proving to be problematic  for appraisers and implementers, both. Both used to refer to high maturity presentations released by the SEI, the appraiser methods or their knowledge of other models/ standards to support of their interpretations. By providing clarity in version 1.3, such subjectivity will thus fade away.

I would say, this is the most important change in the model.

  1. OID PAs has been removed and a new PA, called OPM (Organizational Process Management) has been introduced.

Overall comments:

The new model is more concise with about 100 pages less than its earlier avatar, and with GG4 and GG5 removed.

I will get the book on  V 1.3 of CMMI-Dev in coming 3-5 days and would add to this post in case more differences are found. Rest of the details in the two versions remain the same.

Members may add to these details….

 

The new book on CMMI(R) for Dev., version 1.3


The new book “CMMI for Development®: Guidelines for Process Integration and Product Improvement, Third Edition” is now available from www.amazon.com @ USD 62.36, including shipping and handling charges of USD 9.98. Its ISBN is 0- 321-15496-7 and it is the hard copy version of SEI’s  ‘CMU/SEI-2010-TR-033’. They have started shipping it from 19th March.

Mapping:PMBOK® to CMMI®-Dev, V 1.3


This mapping has been compiled between the Project Management Process Groups and Project Management Knowledge Areas on the x and y axis, respectively;  and  practices of CMMI®-Dev, Version 1.3 in-between them. The Project Management Process Groups and knowledge area matrix is from the PMBOK® and the CMMI® SPs & GPs have been mapped by the author. You may notice that the technical activities (like design) of a  project do not  appear in this compilation, as “Project Management Body of Knowledge” does not and can not cover technical aspects of the project .  Comments and suggestions may please be posted on this blog . Read on

Software Quality Basics



This article was also published in the SEI Repository during the year 2008. It explains the definition of quality in easy to understand language and explains why stated and implied requirements should be collected, analysed and managed with extreme care for leading a software project to successful closure. The article also defines four absolutes of quality as explained by Quality Guru, Philip B Crosby. All of them are more applicable to software projects than other ones, software being something intangible. Read on

Competency matters, not training certificates


This article was first published in the SEI (Software Engineering Institute) Repository. It places significant importance on raising the ‘competency’ of trainees rather than just providing them the subject matter details. So, number of years of experience and/ or qualifications do not matter as much as the ‘competency’ acquired through training, mentoring and hard work. ‘Competent’ people in a project lead it to success.You will find this article quite interesting.
