Lately that the terms Agile and Lean have been thrown around casually with little disregard for what they truly mean and how they can be applied correctly. Join us in this session for a lively, interactive discussion about what it means to be lean and agile and how we can incorporate the principles and practices from each of these industry movements to help us build world class software.

Got process?
Businesses live or die bytheir repeatable processes.
Capability Maturity Model Index
Defined vs. Empirical ProcessesHow would you code an algorithm to keep this room at a constant temperature for the entire day? (What variables would you consider?)Defined processes try to predict the futureEmpirical processes adapt to the futureFrequent inspection Just in time planning
Lean
Eliminate wastePoor requirementsUnnecessary functionality, code, documentationDelays in the development processSlow or poor internal communicationBureaucracyEmpower the team to recognize and eliminate it!
Amplify learningAccept that software development is a continuous learning processIterate to learn and adaptFail early and fail often!
Decide as late as possibleChange happensDon’t fight itAccept it and adapt to itEach iteration should still have an explicit planning phase.
Deliver value as fast as possibleEmbrace continuous deploymentKeep iterations short, short, short!Relish feedback and evolve with the next iteration
Empower the teamAvoid command and control management styleAvoid rigidly defined rolesTeam should have direct access to the customerTeam is responsible for “done done”Give them responsibility and accountability and they will take ownership.
Build integrity inBuild in integrity checks – unit tests become regression testsRefactor aggressively to retain emergent architectural integrityThere should be NO code you’re afraid to touch.
See the wholeUnderstand the whole domain and problem spaceSegregate along functional boundaries instead of cross cutting technical concernsCultivate high value communicationProvide the team with a higher purpose to work towards

What is Agile?AgileAgile is a movement…represented by a set of methodologies…comprised of a set a best practices.ScrumXPFDDOthersCITDDBDDStandUpsBurn-downDomain ModelProductBacklogRefactorPairwise ProgrammingSprintBacklogFeature Team
Agile ManifestoWe are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value:Individuals and interactions over processes and toolsWorking software over comprehensive documentationCustomer collaboration over contract negotiationResponding to change over following a plan
Agile principlesCustomer satisfaction by rapid delivery of useful softwareWelcome changing requirements, even late in developmentWorking software is delivered frequently (weeks rather than months)Working software is the principal measure of progressSustainable development paceClose, daily co-operation between business people and developers
Agile principlesFace-to-face conversation is the best form of communication (co-location)Projects are built around motivated individuals, who should be trustedContinuous attention to technical excellence and good designSimplicitySelf-organizing teamsRegular adaptation to changing circumstances
Agile Practices(by priority)

Agile Adoption“Agile processes have not only gained increasing adoption levels; they have also rapidly joined the mainstream of development approaches.”a “Agile Development: Mainstream Adoption Has Changed Agility – Jan 2010”, Forrester
Agile Adoption“In the past five years, Forrester has seen a growing interest in the adoption of Agile processes. This interest is slowly changing to adoption. In 2008, even shops that weren’t moving immediately to Agile processes began to take baby steps in that direction.”aa “Make Agile Lean – Dec 2008”, Forresterb “Microsoft ALM Consulting Day – Mar 2009”, Forrester presentation; c “State of Agile Development – July 2008”, Version One
