  3. OK(I(am(not(that(shy!( (the(most(influen.al!)( Agile References: "Tom Gilb invented Evo, arguably the

    first Agile process. He and his son Kai have been working with me in Norway to align what they are doing with Scrum. Kai has some excellent case studies where he has acted as Product Owner. He has done some of the most innovative things I have seen in the Scrum community." Jeff Sutherland, co-inventor of Scrum, 5Feb 2010 in Scrum Alliance Email. “Tom Gilb's Planguage referenced and praised at #scrumgathering by Jeff Sutherland. I highly agree" Mike Cohn, Tweet, Oct 19 2009 “I’ve always considered Tom to have been the original agilist. In 1989, he wrote about short iterations (each should be no more than 2% of the total project schedule). This was long before the rest of us had it figured out." Mike Cohn http://blog.mountaingoatsoftware.com/?p=77 Comment of Kent Beck on Tom Gilb’s book , “Principles of Software Engineering Management”: “ A strong case for evolutionary delivery – small releases, constant refactoring, intense dialog with the customer”. (Beck, page 173). In a mail to Tom, Kent wrote: “I'm glad you and I have some alignment of ideas. I stole enough of yours that I'd be disappointed if we didn't :-), Kent” (2003) Jim Highsmith (an Agile Manifesto signatory) commented: “Two individuals in particular pioneered the evolution of iterative development approached in the 1980’s – Barry Boehm with his Spiral Model and Tom Gilb with his Evo model. I drew on Boehm’s and Gilb’s ideas for early inspiration in developing Adaptive Software Development. …. Gilb has long advocated this more explicit (quantitative) valuation in order to capture the early value and increase ROI” (Cutter It Journal: The Journal of Information Technology Management, July 2004page 4, July 2004).

  15. 14#PITFALLS#OF#AGILE#METHODS#( ( • Change – Use of top-down, big-bang organization

    change, adoption, and institutionalization. • Culture – Agile concepts, practices, and terminology collide with well-entrenched traditional methods. • Acquisition – Using traditional, fixed-price contracting for large agile delivery contracts and projects. • Misuse – Scaling up to extremely complex large-scale projects instead of reducing scope and size. • Organization – Unwillingness to integrate and dissolve testing/QA functional silos and departments. • Training – Inadequate, insufficient, or non-existent agile training (and availability of agile coaches). • Infrastructure – Inadequate management and development tools, technologies, and environment. • Interfacing – Integration with portfolio, architecture, test, quality, security, and usability functions. • Planning – Inconsistency, ambiguity, and non-standardization of release and iteration planning. • Trust – Micromanagement, territorialism, and conflict between project managers and developers. • Teamwork – Inadequate conflict management policies, guidelines, processes, and practices. • Implementation – Inadequate testing to meet iteration time-box constraints vs. quality objectives. • Quality - Inconsistent use of agile testing, usability, security, and other cost-effective quality practices. • Experience - Inadequate skills and experience (or not using subject matter experts and coaches). •  (Note. Firms may prematurely "revert" to inexorably slower and more expensive traditional methods or "leap" onto lean methods that may not adequately address common pitfalls of adopting agile methods.) •  Source: David Rico http://davidfrico.com/agile-pros-cons.pdf 2012 Monday,(11(November,(13( ©(Gilb.com( 15(

    to ensure that cost targets are met. 'Cost management. . . yields valid cost plans linked to technical performance. Our practice carries cost management farther by introducing design-to-cost guidance. Design, development, and managerial practices are applied in an integrated way to ensure that software technical management is consistent with cost management. The method [illustrated in this book by Figure 7.10] consists of developing a design, estimating its cost, and ensuring that the design is cost-effective.' (p. 473) He goes on to describe a design iteration process trying to meet cost targets by either redesign or by sacrificing 'planned capability.' When a satisfactory design at cost target is achieved for a single increment, the 'development of each increment can proceed concurrently with the program design of the others.' 'Design is an iterative process in which each design level is a refinement of the previous level.' (p. 474) It is clear from this that they avoid the big bang cost estimation approach. Not only do they iterate in seeking the appropriate balance between cost and design for a single increment, but they iterate through a series of increments, thus reducing the complexity of the task, and increasing the probability of learning from experience, won as each increment develops, and as the true cost of the increment becomes a fact. 'When the development and test of an increment are complete, an estimate to complete the remaining increments is computed.' (p. 474) Source: Robert E.

Estimate expected results and costs for weekly steps "  Feedback "  4. Generate results, weekly, for stakeholders, in their environment "  5. Measure all critical aspects of the improved results cycle. "  6. Analyze deviation from your initial estimates "  Courage "  7. Change plans to reflect weekly learning "  8. Immediately implement valued stakeholder needs, next week "  Don’t wait, don’t study (analysis paralysis), don’t make excuses. "  Just Do It! "  9. Tell stakeholders exactly what you will deliver next week "  10. Use any design, strategy, method, process that works quantitatively well - to get your results "  Be a systems engineer, not a just programmer (a ‘Softcrafter’).

  64. TWELVE TOUGH QUESTIONS! 1. Why isn't the improvement quantified? 2.

    What is degree of the risk or uncertainty and why? 3. Are you sure? If not, why not? 4. Where did you get that from? How can I check it out? 5. How does your idea affect my goals, measurably? 6. Did we forget anything critical to survival? 7. How do you know it works that way? Did it before? 8. Have we got a complete solution? Are all objectives satisfied? 9. Are we planning to do the 'profitable things' first? 10. Who is responsible for failure or success? 11. How can we be sure the plan is working, during the project, early? 12. Is it bno cure, no pay` in a contract? Why not? Monday, 11 November, 13 © Gilb.com 64 There is a detailed paper on these questions at Gilb.com http://www.gilb.com/tiki-download_file.php?fileId=24
