An Introduction to Lean Thinking for Software

For Agile developers only familiar with Scrum or XP, it may be unclear how Lean relates to what they do. This article introduces Lean Thinking and how it enhances software development. Ning Lu of ThoughtWorks China identified the biggest obstacle to Lean or Agile as the mind-set developed during the period of large-scale manufacturing.

Using Numbers to Communicate - in the Spirit of Agile

It's an old story. Techies cave in to the business guys because they don't know how to push back. The problem? Developers use numbers primarily for computation, but the business uses numbers to make decisions. In this story the "Spirit of Agile" encourages a developer to turn non-computational problems and issues into number language.

Creating Product Owner Success

The role of the Scrum Product Owner is powerful, but challenging to implement. Success can bring a new and healthy relationship between customers/product management and development, even competitive advantage, but it comes at a price: organizational change is often required. In this article Roman Pichler looks at what it takes to succeed as a Product Owner.

The Three M's - The Lean Triad

The discussion of applying lean principles to software development has largely focused on identifying and eliminating waste (in Japanese: muda). Lean Thinking equally aims to remove overburden (muri) and unnecessary variation (mura). Roman Pichler discusses the relationship of the "three M's" and proposes to eliminate overburden as the first step toward a leaner process.

AgileEVM: Measuring Cost Efficiency Across the Product Lifecycle

In this InfoQ article, Tamara Suleiman explains AgileEVM, an adaptation of traditional Earned Value Management (EVM) metrics, designed to fit a Scrum project management framework. Compatible with traditional EVM metrics, it allows both Agile and traditional projects to be tracked within a single program, giving important early warnings of trends across the entire product life cycle.

The Secret Sauce of Highly Productive Software Development

When Agile teams get stuck in the just-average Norming stage, rather than continuting to the exciting, high Performing stage of teamwork, sometimes they're suffering from an invisible "learning bottleneck" that stunts team performance. Agile practices require us to take time to reflect and learn - and a team that learns quickly succeeds.

"Real Options" Underlie Agile Practices

Whether we realise it or not, "freedom to choose" is a principle underlying many Agile practices. By avoiding early commitments, we gain flexibility in the choices we make later. In this article, Chris Matts and Olav Maassen propose that an understanding of "Real Options" allows us to develop and refine new agile practices and take agile in directions it hasn't gone before.

Culture & Methods

Case Study: Targeted Practice Adoption using Patterns

It's easy to forget what originally motivated us, once we're implementing Agile. Teams spin, trying to figure out which practices to start with, unsure which will have the biggest impact, or how they fit together. Amr Elssamadisy and John Mufarrige propose a customized adoption approach to help teams decide where to focus first - an alternative to adoption of pre-packaged methodologies.

Standish: Why were Project Failures Up and Cost Overruns Down in 1998?

Following InfoQ's August interview with Jim Johnson, creator of the CHAOS Chronicles on project failure, one important question remained: how does the Standish Group explain the amazing change in cost overrun from 189% in 1994 to 69% in 1998? In an excerpt from this month's CHAOS University newsletter, Johnson refers to events in 1996 that changed the complexion of project planning and execution.

Book Excerpt: Implementing Lean Software Development: From Concept to Cash

In 2003 Mary and Tom Poppendieck adapted the revolutionary principles of Lean manufacturing for software development. Their new book offers a blend of history, theory, and practice, drawing on their experience optimizing the software "value stream". They present the right questions to ask, the key issues to focus on, and techniques proven to work for those implementing a lean software process.

Interview: Jim Johnson of the Standish Group

Jim Johnson, founder and chairman of the Standish Group, took time out from his vacation to talk with InfoQ editor Deborah Hartmann about his research, and the role of Agile in changing the IT industry. Johnson is best known for creating the CHAOS Chronicles: 12 years of independent research on project performance, including data on over 50,000 completed IT projects.

Executive summary - An Adaptive Performance Management System

Traditional thinking has turned budgets into fixed performance contracts forcing managers at all levels to commit to specified financial outcomes, although many of the underlying variables are beyond their control. In this Cutter Executive Summary, Jim Highsmith offers an alternative for the adaptive organization: a project performance management system and a team performance management system.
