Creating Shared Understanding At High Complexity through Story Mapping, Spec By Example and Domain Driven Design

schedule Oct 30th 10:30 AM - 12:00 PM place 206C people 29 Interested

Shared understanding is a pre-requisite to success for any agile teams. Many Agile teams rely on User Stories to help them get consensus on what to deliver, and what done looks like. Stories are a great practice for agile teams, but as the complexity of the problem or solution they are building increases, they often need more. Agile teams can face serious churn in the story writing process as complexity increase. Different team members can have completely different understandings of the meaning of key business and solution concepts. Often the same concepts end up being discussed over and over again, significantly slowing down story exploration. Even worse, different stakeholders end up having ambiguous and even conflicting understanding of the solution.

During this session, we will discuss how we have integrated story exploration practices such as Story Mapping, Story Grooming, and Spec by Example, with the Domain Driven Design method, with the goal to promote the creation of a ubiquitous language and share understanding of both the solution and business domain. We will show how various teams have leveraged light weight, informal tools to enable both technical and non technical stakeholders to execute in a highly aligned way, and dramatically decrease churn and rework as a result.

A key part of this session will be taking the audience through an integrated example that show cases how one can elaborate on an idea through progressive refinement of Stories and CRC Card based domain driven models in parallel. We will showcase how Story Maps can be refined through creation of an initial Domain Driven Model expressed through Class Responsibility Cards. We will illustrate how to connect story grooming and refinement of domain models in order to create a precise business and solution language. We will illustrate how domain model walkthroughs can be used to battle test your stories against your domain model, validating key assumptions before coding starts. We will also showcase how both story grooming and domain driven design can be done directly in code, and how this approach dovetails perfectly into test driven development.

    Ellen Grove - Making our Mark: Drawing Together to Enhance Collaboration

    90 Mins
    Workshop
    Beginner

    Co-creating drawings helps teams enhance their systems thinking abilities by really seeing the big picture. A group of people talking around a whiteboard is an effective way to share ideas across a team. Imagine how much richer the conversation is when everyone on the team has a marker in their hand and is actively contributing! Graphic visualization is an important tool for talking about new ideas, generating insights and developing shared understanding. In a team context, drawing is a thinking tool rather than an artistic endeavour. When everyone participates in creating drawings, all team members can see how things fit together and what mental models are at play in defining the situation. And, by drawing together, the team is collaboratively creating meaningful records that are being validated and updated.

    Come along on a visual adventure into how teams can collaboratively visualize ideas and make sure that everyone at the table has a voice. In this workshop, we will warm up with some basic doodling skills practice. No drawing experience is required to take part in this session: if you can hold a marker, we can teach you the skills needed to put your ideas on paper. Together we'll consider the ways that collaborative drawing can be used to enhance group work, and we will share practical activities that you can take back to use with your team for setting the stage, gathering information, and sharing stories.

    Abstract (280 chars)

    What if you could organize and motivate people to double their highest-expected productivity goals? Lessons from a large, distributed, volunteer group of online video gamers offer practical 21st-century guidance for your workplace. Even if you aren't a gamer. Or a space pirate.

    Abstract (full)

    What if you could gather and motivate people to double even their highest-expected productivity goal? What if you had no authority over those people -- if they were all volunteers?

    The future of leadership is emerging to guide 21st-century organizations beyond the small, cross-functional, green-field software development teams of the 1990s. Agile enterprises must respond to emerging markets, provide unity of purpose to workers with conflicting motivations, and foster order when change is the only constant. Agile leadership must cope with distributed teams, "gig economy," diverse skill-sets, and the impact to morale of unexpected changes. But the measure of success is still delivery to the market: volume, quality, reliability.

    Early in 2017, a group of several hundred independent players of the online futuristic video game Elite:Dangerous faced all the above organizational challenges yet still managed unprecedented delivery to their market. And they did it despite the "me first" culture of online games.We'll explore the structural, social, and cognitive factors which enabled this large distributed team of casual volunteers to deliver twice as much as their nearest competition. And we'll uncover how to amplify those factors in your own workplace.

    You'll learn the powerful effects of making individual contributions visible, expanding the scope of your regular team synchronizations, having a loose leadership hierarchy, and encouraging diffusion of innovation. And you'll see how community engagement is an essential quality of a servant leadership culture. This is a compelling story about leadership that's relatable to anyone regardless of their interest in or experience with Agile, online gaming, or space pirates.

    60 Mins
    Talk
    Intermediate

    “When will it be done?” is a question asked in just about every business I’ve encountered, Agile or otherwise. In this metrics-focused session we will explore why that question is so hard to answer and whether it is even the right question to ask.

    We will explore current thinking about measurement in knowledge work fields. How every business needs to identify their own appropriate metrics to measure for their own business challenges and goals. While metrics are always unique for each individual business context, we will identify 4 metric categories identified from the Fit for Purpose framework.

    To connect these concepts to your Agile organization we explore going past looking at measurement as a team phenomena and connect this to the level of services or value streams.

    Digging further we continue to examine questions around measuring and predicting delivery times. We contrast prediction approaches using deterministic methods vs probabilistic methods. And consider multiple sources of variability that make predictions challenging and often impossible.

    We conclude by considering more appropriate questions to replace “When will it be done?” Rather asking “When do we need it” followed by “and so, when should start?”

    Fernando Cuenca - Visualizing Work: If you Can't See It, you Can't Manage It

    60 Mins
    Talk
    Intermediate

    Unlike a factory, where we can see work literally moving around, piling up waiting, being worked on, or even deteriorating with time, knowledge workers have to deal with abstract constructs that are largely invisible. Suddenly, answering questions like "what are we working on?" or "how does work get done here" can become tricky.

    The basic premise that the first step towards effectively managing knowledge work is to make it visible will not come as a surprise for anyone with some familiarity with Agile. That said, there's more to effective work visualization than a 3-column board showing "To Do | In Progress | Done" columns, and visualizing work items is only the first step.

    This session will explore approaches for visualizing otherwise invisible aspects of work, such as commitments, process, rules and, of course, work items, and using them to enable more effective management and collaboration.

    Scott Ambler - Choose Your WoW! A Disciplined Agile Delivery Handbook for Optimizing Your Way of Working (WoW)

    60 Mins
    Talk
    Intermediate

    We like to say that agile teams own their own process by choosing their way of working, their “WoW.” This of course is easier said than done because there are several aspects to WoW. First, our team needs to know how to choose the appropriate lifecycle for the situation that we face. Should we take a Scrum-based approach, a lean/Kanban-based approach, a continuous delivery approach, or an exploratory/lean startup approach? Second, what practices should the team adopt? How do they fit together? When should we apply them? Third, what artifacts should the team create? When should they be created? To what level of detail? Finally, how do we evolve our WoW as we experiment and learn?

    There are several strategies that we could choose to follow when we tailor and evolve our WoW. One approach is to bootstrap our WoW, to figure it out on our own. This works, but it is a very slow and expensive strategy in practice. Another approach is to hire an agile coach, but sadly in practice the majority of coaches seem to be like professors who are only a chapter or two ahead of their students. Or we could take a more disciplined, streamlined approach and leverage the experiences of the thousands of teams who have already struggled through the very issues that our team currently faces. In this talk you’ll discover how to develop your WoW without starting from scratch and without having to rely on the limited experience and knowledge of “agile coaches.”

    Workshop
    Beginner

    A supported Product Owner has the power to prioritize. An empowered Product Owner has the power to say 'No'!

    The Product Owner is the most underutilized and unsupported role in large organizations that are trying to increase their speed to market. Product Owners are only business people playing a 'weekend dad' to the team or they are merely only writing requirements for the team.

    Companies that are successful in delivering products to market empower the Product Owner. The Product Owner has one leg in Product Management and the other leg with the Scrum Team. The empowered Product Owner engages the business, customers, engineering, design, sales groups as stakeholders. They are empowered to optimize value by creating vision and context to enable teams to deliver products people want to buy and are technically sound to maintain and scale.

    In this workshop, we will help you unleash this opportunity and guide you in understanding the role of an empowered Product Owner.

    Agile has been pervasive and proven to be successful for technology product development for more than two decades. Today more organizations are taking agile principles and practices and applying them outside of IT to their business as usual (BAU) activities such as marketing or strategy development. But how easy is this next generational aspect of Business Agility? Can an approach that was rooted in technology product development be successfully applied as an accelerator to achieve overall business efficiency and effectiveness?

    In this session, different case studies, including a large Canadian insurance provider, will demonstrate lessons learned from organizations that have taken agile principles and practices to help them drive commercial impacts, build people and their capabilities, adoption of the right mindset and behaviors, and improve performance. Some of the questions that will be addressed:

    • What does business agility mean and why does it matter?
    • How can Corporate Functions such as HR, Finance, Risk and Marketing, which are often entrenched in traditional ways of working, become agile delivery centers?
    • Do agile practitioners need to “stay true” to the principles and practices they originally learned for technology in order to be effective in the business?
    • How should agile business teams be optimally structured to align with an enterprise agile COE?
    • What can leaders learn from others’ journeys so we can determine whether agile can truly thrive outside IT and be scaled across the organization?

    If you are a Business Leader who is considering next steps on enterprise agility, organizational resilience, and a culture of adaptability, attend this session to learn valuable and pragmatic insights as you begin your own agile journey.

    Collaboration is generally considered a net positive, and everyone knows it’s a key principle of Agile. Yet most Agile teams -- even those that seem to work well together -- don’t collaborate nearly enough, and thus don’t reach their full potential. It takes attention and work to make collaboration possible, let alone appealing and practical! In this interactive talk, the author of “The Human Side of Agile” explains the not-so-short list of not-so-simple factors that get in the way of real collaboration, and provides a process for determining actions that will make collaboration possible.

    Kaizen Events can bring people together from all levels of your company to tackle particularly knotty problems. Leaders or Agile Coaches can use them to help create and support a culture of learning by developing skills and emergent leadership. They are usually five-day-long events that include problem definition, research, data collection, brainstorming and solutioning, resulting in a plan.

    In this session, not only will we tell you what a Kaizen Event is, but also show how an experienced leader or practitioner can put one together, and still get it wrong. We’ll share our learnings from our first Kaizen Event at FreshBooks, so that that you can avoid some of our mistakes. We’ll cover what a Kaizen event is, how you can benefit, and how to organize one. We’ll also share details like logistics, success metrics, messaging, problem solving and solutioning tools.

    Wave 2 is about Living Agile. It is how we show up. It is how we work with people and organizations to shape the Culture. It is living Mahatma Gandhi's truth:

    “Be the change that you want to see in the world”.

    When we focus on our own behaviour, we model Being Agile. This is the only way to invite the Agile Mindset. This is Wave 2 Agile. We stop creating conflict and resistance. We become the effective leaders and influencers of lasting change in our organizations.

    Agile is an incremental and iterative approach to delivering value to our customers. But too often we assume it’s really all about ways to slice work into smaller batch sizes and that both approaches are fundamentally equivalent. However, there is a crucial difference and this lack of awareness is a major contributor to projects and teams that are AINO (Agile In Name Only)!

    In this session, we will discuss how to differentiate between incremental and iterative approaches, their strengths and weaknesses, and why you really need both. We will explore the many ways in which iteration shapes the core of Agile practices, how it supports and enables the benefits of agility, and how understanding its awesome power is a key step in moving from “doing” Agile to truly being agile. In addition, we will take a close look at the practical implications of when to use each approach by discussing real world scenarios, highlighting common Agile anti-patterns and (re)examining familiar story slicing patterns.

    You will walk away with both a better understanding of one of the most important underlying principles of agility and immediately applicable insights for your daily work!

    Agile is about keeping pace with change. Inclusion ensures we bring everyone along with us.

    Agile initially brought a bunch of individuals cross-functional specialists together to work as a team. This cross-functional team was able to deliver complex products more quickly. The concept of diverse teammates looking at a problem and sharing their perspective from their skill background proved to be the ideal way in creating solutions that meet the needs of domestic customers.

    As companies execute on their digital strategy, products are now global. Having cross-functional teams are no longer sufficient. Agile teams need to be cross-functional AND diverse to meet the needs of global customers.

    In our talk, Dave and Dave will discuss the importance and competitive need to make your teams diverse. They will also share their experiences of integrating diverse members into the team.

    Many of us have felt the benefits of Agile. Working in cross-functional teams, learning from others in your team, the freedom of self-directedness and self-organization, the decrease in email madness and the value of quick bursts of communication through stand-ups and other cadences, have all enhanced the way that we work.

    But I’m sure we’ve also experienced Agile growing pains. One common pain is developing a solution that ends up falling short of Business expectations and need. This adverse outcome leads to Agile teams potentially feeling disengaged and undervalued; it can cause a strain in the Business/Agile relationship; and it can result in painful and seemingly endless feedback loops to attain a satisfying result.

    During this session I will share a few tips that have worked well for us in bridging the gap in understanding that result in less-than-satisfactory Business results. They include:

    • Introducing the concept of Human Centered Design (HCD) to the Business
    • Providing the Business with a basic Agile understanding to enable effective communicate with their Agile partners
    • Training both teams on light weight, informal tools to enable stakeholders to communicate and execute in a highly aligned way

    By taking these steps we have witnessed a more symbiotic relationship immerge between technical and non-technical teams. We have created ways to help visualize where we have inserted HCD and Agile to help foster this enriched relationship, and we will share these images in our presentation.

    Agile has now gone mainstream. Starting new and more Agile teams is relatively easy, but organizations then run into the challenge to orchestrate the work of multiple agile teams. Some have even observed that even though they manage to obtain better results from individual teams, if they step back and look at the larger picture, work still takes a long time to be delivered, quality expectations are not met, and teams experience considerable "friction" when they interact with their environment.

    This session is directed to those managers that operate above the team (middle-management, director level, etc.) and explores the concerns that need to be considered to create a context in which those Agile teams can thrive and realize the promise of high-performance.
