Avoiding Coupling and Using Mocks (audio of the webinar) Scrum# is an extension to Scrum that was developed by Net Objectives to solve challenges that were being encountered by many teams adopting Scrum. Read about more about the issues which Scrum# was created to solve. A webinar on September 02, 2008 presented by Alan Shalloway discusses how, in Agile projects, neither full up-front designs nor no design proper. This webinar discusses some techniques for decoupling modules early on. In other words, although we may not know how things will change, we often know of dependencies between modules that will morph over time. He presents three case studies: Decoupling informational dependencies between components How to define the API for a component being built by one group and used by another Using mocks to never be blocked - avoiding delays caused by dependencies of different tiers The webinar is available to registered users of the Net Objectives website for 30 days and to Net Objectives customers always.

The Six Lean Transitions that Got Us to Where We Are At a recent meeting, Al Shalloway discussed the six key transitions in Lean that has led to where we are in the application of Lean to software development. We found it very helpful in understanding where we have come from, the advantages that each phase offered as well as the challenges inherent in them that needed to be addressed. Looking back helps to get a good perspective of how we got where we are and it helps in thinking about what may lie ahead. Al suggests there have been six major transitions or phases: Lean Manufacturing, Lean Thinking, Lean Product Development, Lean Software Development, Lean Flow, and Lean-Agile Software Development (the current state of the art). We can now say that for an approach to be Lean and useful to software development, it must include the following: Systems thinking, using management to improve system, attending to quality, emphasizing just in time, attending to time, attending to how people learn, driving from value, and maximizing feedback. Here is a book to help you go deeper: Lean-Agile Software Development: Achieving Enterprise Agility You can use the forums on the Net Objectives Portal to ask questions about the webinar.

[background music] Jim: Hello and welcome to another edition of "Lean Agile Straight Talk," a regular podcast series from Net Objectives. I'm your host, Jim Trott. In this show Steve Thomas discusses what is involved in bringing internal coaching in a lean agile transformation up to the next level. Why coaches are needed? What's involved? The difference between internal and external coaches? Who makes good coaches? What's involved in developing internal coaches using matrics and so on? We had lots of questions from the audience, so clearly this is a topic of interest to many people who are engaged in a lean agile transformation. We need to visit this topic again. Before we get started, I want to remind you that you can explore more about this topic by jumping over to the resources section of www.netobjectives.com. I suggest you search for Coaching Academy. There's a lot of good resources on there about this topic area. At Net Objectives, we're committed to discovering effective software development methods so that we can assist organizations in becoming more successful. We combine our experience to continuously extend the capability of what is possible in creating effective software development organizations. We provide these approaches to our clients and the community in general so that we can assist people in achieving their goals in making their organizations more successful. We'd welcome the chance to work with you. We're always learning and invite you to join in. Visit us at www.netobjectives.com. Please subscribe to the Lean Agile Straight Talk Podcast on iTunes and rate the show. That really helps. Let's keep the conversation going. Today's presenter is Steve Thomas. Steve is a certified Scrum Master and product owner, and an Agile and Lean coach. He is an experienced facilitator of Agile transformations in large organizations and in all phases of the software development life cycle. In addition, he has been a CMMI authorized instructor. One of Steve's passions is to work with cross functional teams, managers and organizations to establish work environments where collaboration blossoms, and productivity and results sharply rise. He brings systems thinking, Lean and Agile principles in a pragmatic outlook to this work. The general topic today is on bringing your internal coaching to the next level. Let me set the stage. Almost all medium to large size organizations that are trying to make a Lean or Agile transformation must develop an internal coaching capability. Relying on external coaches is just too expensive and it's not tuned enough to the needs of the organization. Organizations have a clear need to leverage some of their internal talent and people to coach the organization through the transition and into the next stage of transformation. In most transformation journeys, we're going to start with bringing in some trainers or coaches to help the organization understand the basics. Once the transformation journey's

Bringing Your Internal Coaching to the Next Level

Skills that Developers Need to Acquire to Achieve an Agile Transformation Amir Kolsky, Rob Neppel, and Jim Trott talk about eight essential skills that developers need to acquire to work in an Agile transformation. Some of these skills are certainly taught in university; some are not as common... but are still essential. These are essential for any professional developer. The essential skills are: Programming. The programmer needs to know how to program. The act of taking a design and implementing it in a language and environment. Design. Creating a good Object-Oriented design based on design patterns. Depends on understanding the specification. The challenge in Agile is that the specification is always changing. You need to know how to create emergent design. TDD helps here. Refactoring. Pre-factoring (before you make changes to the code) and Post-factoring on legacy code to deal with the code smells. Analysis: Domain analysis and technical analysis. Working with stakeholders to understanding the specifications and to create specifications up front on what is necessary. ATDD is essential here. Communication is critical here because developers are actively engaged in every aspect of the process. ATDD and TDD helps to facilitate communication. Testing. This can be learned from the testers in the organization. Estimation. DevOps. Looking further down the value stream, extending the definition of done into deployment. Continuous Intergration is just the start of this. Process Improvement. This is a discipline that the entire team must embrace..

Now, some of these skills are certainly taught in university and some are not as common, but they're all essential. They're essential for any professional developer to have. In the course of this podcast, Amir Kolsky will describe these eight skills and I think it would be helpful to list them out right at the start just so they're fresh in your mind. Here are the eight skills that Amir says all developers need to know. First of all, how to program. How to design, creating a good object‑oriented design based on design patterns, emergent design. Refactoring, both before you start to make changes and dealing with legacy code to reduce code smells. Analysis, both domain analysis and technical analysis, and effective communication. Testing, one of those great skills that we can learn from our testers in our organization. Estimation, DevOps looking further down the value stream extending the definition of done into deployment, and the discipline of process improvement. Rob and Amir are going to talk a lot more about all of these in the podcast.

Skills that Developers Need to Acquire to Achieve an Agile Transformation

Start Stronger, Get Better, and Do More: A Conversation with James Sutton and Marc Danziger James Sutton, Marc Danziger, and Jim Trott talk about transformation, systems thinking, the borders that Agile erects that can inhibit scaling, coaching, and why Lean thinking requires you to start with understanding the existing culture. Jim Sutton summarizes this as "Start Stronger, Get Better, and Do More." Start Stronger involves "how to start with much-better value candidates"; Get Better focuses on how to walk into a transformation; and Do More is the Lean principle of Perfection. This comes from their long experience with Lean, systems, and helping organizations and programs both large and small scale and succeed. With Lean thinking and Agile practices. Because the reality is that Agile transitions do not always scale up. As Jim Sutton says, success in a little thing does not mean you will have success just by doing more and more of that little thing. Scale requires more approaches, different kinds of thinking. At first, I wondered if this would seem a little academic. But, as we got into it, it became apparent how helpful this is, especially to someone who is having to coach a transition in an organization. There is a lot to think about.
