Agile Dev East 2017 - Concurrent Sessions

User stories and their big brothers, epics, are an excellent way to describe requirements for a software system. They act as stakes in the ground to keep track of what the system needs to do, the type of user most interested in each feature, and the reason the requirement provides value. As projects reach a certain size, stories often become too large for a team to complete within a single sprint. The solution? Split them into smaller stories, each of which can be completed within the duration of one sprint. Dave Todaro describes proven techniques to split epics and stories, making...

Measuring software development is difficult. Measuring the return on investment (ROI) of complex initiatives (such as adopting agile) is even more difficult. One department at IBM struggled to reduce a list of 150 metrics down to a top twenty to use in consulting engagements. Through the years, nearly every one of Anthony Crain’s clients has asked him for help in proving that their teams were “getting better” at development. Nearly all of their measures were “adoption” measures showing how teams were doing agile. However, none of the metrics was focused on whether the development was...

As development teams move toward a more agile development process coupled with continuous delivery (CD), the role of operations has evolved from a support organization to an integral part of the product delivery ecosystem. Today, operations organizations need to be agile in their feature delivery, but as requests come from different stakeholders, operations must balance their investments in support tasks, urgent tooling requests, and strategic projects. Sumedha Ganjoo explains why it is important for an operations organization to move toward CD and identifies process, tools, and...

Are you looking for ways to ensure your teams are always working on the highest customer value ideas? Do you want the ability to quickly adapt to microchanges in the market? Do you want end-to-end visibility of work across the enterprise from inception to delivery? If so, this session with Mario Moreira is for you. Discover how to operate in an agile manner at every level of your enterprise and gain the business benefits it can bring. Mario explores innovative concepts such as enterprise kanban, lean canvas, cost of delay, agile budgeting, discovery mindset, incremental thinking,...

Do your product teams frequently struggle to have groomed and well-defined stories ready for the developers? Do you find yourselves frequently in “feed the beast” mode to keep your development teams busy? Do your product teams have problems gaining shared understanding across product management, interaction designers, developers, and QA? If so, your product teams manifest the symptoms of single-track agile—and this session is for you. Sean McKeever explains the key steps in establishing dual-track agile methodologies at your organization, presents his experiences, and provides...

Imagine a world where operational data is continuously flowing from applications and devices at an extremely high rate. Now imagine services intercepting this data and analyzing it real time. Sounds futuristic? It's not—it's here today. Mark Richards describes what streaming architecture is all about—what it is, when to use it, and how to implement it in a microservices ecosystem. Mark describes the overall ecosystem for streaming architecture—including a brief discussion about the differences in Apache Spark, Flink, and Hadoop—and then explains how Apache Kafka works. Using live coding...

Intermittent failures ruin the whole premise of continuous delivery (CD). In fact, they undermine any software QA process, since they break the fundamental assumption that if your test suite passes, you are good to deploy. Automated testing can run orders of magnitude more tests than manual testing but may result in an ever growing backlog of tests that fail intermittently for reasons that aren’t understood. Whether this is embarrassing, annoying, or scary depends on your sensitivity to risk. No matter the level of your pipeline’s sophistication, you need to reproduce the defect before you...

Organizations claim to be going agile. Many agile leaders promise twice the results in half the time. Unfortunately, most organizations and leaders fail before they even start. In five basic concepts Lee Henson shares the reasons for their failures. First, focusing on the outcome instead of the output is critical for agile project success. Second, organizations that succeed are those that take time to eliminate technical debt and focus on test automation. Third, as organizations strive to be precise in their estimates, they are learning that time-based estimation was never intended...

Have you heard that only 36 percent of business features built into software are actually used by end users? And why do we get functionality that fails to work as expected? One of the age-old problems between IT and our clients is that we don’t speak the same language. Sheetal Patel shares her experience of how behavior-driven development (BDD) introduces the bridge of common language that both IT and non-technical, business clients can speak to build the right product. Sheetal explains how collaborating on agile teams with BDD gains a common understanding among developers, testers...

After you hear Stephen Frein's keynote on intelligent software, join him for a hands-on tour of machine learning techniques. Using the free R language and the RStudio IDE, Stephen guides you through a sampling of machine learning techniques and discusses how these techniques can be used for both understanding and prediction. Follow along as he extracts data from online sources and builds machine learning models in real time to predict numeric values, assign classifications, and categorize textual sources of information. Experiment with the demonstrated methods by modifying the code and...

Large organizations can be filled with manual processes, and many people feel they are stuck with them. Bill Roberts and James La Spada tell the story of how Capital One used DevOps culture and kanban principles to significantly increase the speed of feature delivery—while lowering risk. Their team took the name Meteor, inspired by the big one that took out the dinosaurs, because they wanted to cause the mass extinction of these manual processes. Work at Capital One was previously completed manually, and many inefficiencies were evident. Bill and James helped drive the...

Many organizations make huge investments in software testing, and unfortunately they often don’t understand or extract full value from these activities. This can lead to testing being viewed as a mere formality or necessary evil within an organization. Fortunately, we can deliver more value with relatively minor adjustments to our approaches. The transition to agile practices provides a natural opportunity for test specialists and others to put these adjustments into practice. Plan-driven approaches can also be adjusted to increase the value delivered from testing activities....

We humans process millions of bits of information each day. In order to handle that data load, our brains have developed shortcuts to take advantage of patterns, shared knowledge, and experience. Unfortunately, sometimes those shortcuts lead us astray, causing us to draw inaccurate conclusions. Faye Thompson says these shortcuts are amplified when we bring together a team of people, all trying to work together. Understanding how and why our brains take shortcuts to process all the incoming data can help us recognize when it's happening, take measures to correct our course, and even use...

Docker seems to be taking the IT world by storm. But why all the excitement about yet another virtual machine technology? Because Docker is much more. Korey Earl says that Docker solves many DevOps challenges including process isolation, build once-deploy anywhere, and automated scaling without the resource overhead that comes with virtual machines. Docker can improve resource utilization, infrastructure agility, and the transition from development to operations, allowing IT organizations to support the business rather than holding it back. Join Korey as he reviews the basics of the Docker...

Organizations transitioning to agile often hire external consultants to help them become more agile. However, what tends to happen six months after the consultants leave is that the organization is often left with more—and different—problems than they had before. Susan Lin says this happens because the organization was not set-up to deal with the new challenges. Susan shares the Help Agility Stay framework and shows how you can help your organization grow and sustain agility by applying the three main principles of the framework—create a shared vision of agility, co-create a...

Creating a cohesive team doesn’t require knowledge of dark arts or forbidden rituals. In fact, under the right circumstances, it can even be fun! Using exercises built around the LEGO® Serious Play® (LSP) methodologies, Paul Wynia explores techniques that ensure full team engagement and collaboration resulting in more meaningful discussions. Working as teams, discover Team Values using a series of individual and collaborative LSP builds. Once the Team Values are defined, use them to guide your team’s behaviors. These are finally turned into the Team Working Agreement, a powerful tool for...

Most of us dread failures. But things go wrong. We can become paralyzed by the fear of being the creator of the next outage or critical bug. After a failure, we often hold a postmortem, but this rarely addresses how we can be more proactive in preventing catastrophes. Considering our missteps, failures, and outright crash and burns, we can learn how to ask the right questions at the right time. Siva Katir has thirteen years of experience causing and surviving failures—from the mundane to the maddening. Siva shares the lessons he has learned analyzing his, his co-workers, and his...

After predominantly being used in the build/test stage, Docker has matured and is expanding into production deployment. Similarly, microservices are expanding from greenfield web services to use throughout the enterprise as organizations explore ways to decompose their monolithic systems to support faster release cycles. Anders Wallgren says running microservices-based systems in a containerized environment makes a lot of sense—both for build and test, and from a runtime perspective in production. This makes Docker and microservices natural companions, forming the foundation for modern...

Scrum is everywhere. More than 90 percent of agile teams use it. But for many organizations wanting to scale agile, one team using Scrum is not enough. Dave West says the Nexus Framework, created by Ken Schwaber, the co-creator of Scrum, provides an exoskeleton for Scrum. Nexus allows multiple teams to work together to produce an integrated increment regularly. It addresses the key challenges of scaling agile development by adding new yet minimal events, artifacts, and roles to the Scrum framework. Dave discusses Nexus, addresses its boundaries, and explains what else is needed for agile...

The change in mindset necessary to become a servant leader is incredibly hard for a scrum master who comes from a command and control background. As a newly minted Professional Scrum Master (PSM I), Ryan returned to his team excited and ready to get underway with a scrum adoption, but he had not fully grasped the concept of servant leadership. Instead of being a change agent, he was an impediment. Ryan’s cautionary tale is a common one. Attendees will learn about the difficulties of becoming a scrum master, how scrum team members need to embrace the scrum values to promote healthy team...

Two common situations lead to bad software—the project team isn’t aligned on the problem or the customer isn’t involved in the design process. Either way, you end up with a product that the business didn’t ask for, the tech team struggles to deliver, and customers don’t want. So, how do you increase confidence in the direction of your product and work together to build innovative solutions that bring the business, technology, and customers together? Garren DiPasquale and Matt Wallens introduce, a process to understand business goals and customer needs. It isn’t about designing screens or...

DevOps is transforming software development with many organizations adopting lean development practices, implementing continuous integration (CI), and performing regular continuous deployment (CD) to their production environments. However, the database is largely ignored and often seen as a bottleneck in the DevOps process. Steve Jones discusses the challenges of database development and why many developers find the database to be an impediment to the CD process. Steve shares the techniques you can use to fit a database into the DevOps process. Learn how to store database code in a...

A hierarchy is an organizational network that has a top and a bottom, and where position is determined by rank, importance, and value. A holarchy is a network that has no top or bottom and where each person’s value derives from his ability, rather than position. As more companies seek the benefits of agile, leaders need to build and sustain delivery capability while scaling agile without introducing unnecessary process and overhead. The Agile Performance Holarchy (APH) is an empirical model for scaling and sustaining agility while continuing to deliver great products. Jeff Dalton...

As teams grow, organizations often draw a distinction between feature teams, which deliver the visible business value to the user, and component teams, which manage shared work. Steve Berczuk says that this distinction can help organizations be more productive and scale effectively, but he recognizes that not all shared work fits into this model. Some work is best handled by “specialists,” that is people with unique skills. Although teams composed entirely of T-shaped people is ideal, certain skills are hard to come by and are used irregularly across an organization. Since these...

If you're using user stories for your agile requirements, you're not alone. They seem to have become the ubiquitous vehicle for communicating customer requirements to agile teams. And they work incredibly well in this regard. However, many teams are experiencing problems with them. Bob Galen does not believe it’s the story’s fault. Bob says we often forget the “conversation” part of the story—and more importantly, the storytelling part. When Kent Beck first described the idea of the user story, his original intent was to initiate or inspire a story-level conversation between a stakeholder...

With the recent emergence of DevOps across the industry, testing organizations are being challenged to transform themselves significantly within a short period of time to stay meaningful within their organizations. It’s not easy to plan and approach these changes considering the way testing organizations have remained structured for ages. These challenges start from foundational organizational structures and can cut across leadership influence, competencies, tools strategy, infrastructure, and other dimensions. Sumit Kumar shares his experience assisting various organizations to overcome...
