schedule Oct 24th 01:00 PM - 01:45 PM place Room 5

It can be difficult for developers to find the motivation to write automated unit tests.  This workshop introduces a simulation that can demonstrate the value of automated unit tests to identify and localize defects.  In the simulation, participants will play the roles of programs and tests.  We will discuss barriers to creating and maintaining unit tests, and how this simulation addresses those barriers.

Theme: Games for Learning, Code and Test

Outline/structure of the Session

Introduction: Brainstorming (15 Minutes)

We will have participants at each table brainstorm on obstacles to getting developers and groups to write unit tests.  We will share these with the group as a whole. 

Simulation: Round 1 (10 Minutes)

We will have one person at each table act as a computer.  They will be given an ordered deck of cards, representing a program, and a set of constraints this program must satisfy.  The task of the “computer” will be to “execute” the program by turning over one card at a time and say whether the cards meet the given constraints.  In this round, the rest of each table observes.  We will time the process and discuss the outcome. 

Simulation: Round 2 (10 Minutes)

We will keep the same person in the role of the computer, and we will give the person a new program. However, this time, several others at each table will each take the role of a unit test checking a single constraint.  As the computer “executes” the program they will be able to validate the correctness of the program.  We will discuss the process and outcome, and how it compared to the previous round.

Wrap-Up (10 Minutes) 

We will discuss which of the obstacles to introducing automated unit tests are potentially addressed by the simulation.

 

Learning Outcome

Participants will learn a simple simulation that illustrates the power of automated unit tests.

Target Audience

Folks who are interested in learning about the power of automated unit tests, or looking for ways to share this knowledge with others.

    Many team challenges can be tracked back to cognitive biases: our judgement gets anchored, we think we're better than we are, and we are our own favorite reference point. And even though we're encouraged to "think outside the box," there are conditions where we have a bias against creativity. If that's not a recipe for a tough team environment, I don't know what is.

    Improve your game by learning about bias! You'll leave this session with strategies for identifying and mitigating bias on your team.

    Retrospectives are the core of agility. And yet they are the scrum ceremony that is most frequently skipped. Many teams like the idea of the retrospective but find them boring, or worse ineffective.

    This talk aims to re-energize retrospective facilitators and participants. Starting with the basics: "what's a retrospective and how do you run one?", this talk reveals 7 secrets that lead to more engaging, more effective retrospectives.

    You'll learn:

    * The best way to ensure your retrospectives lead to real change

    * The "pledge" everyone on your team should take before participating

    * How to know who to include in each retrospective

    * The single most important thing you can do to keep your team engaged during the retro

    * And much, much more!

    45 mins
    Workshop
    Beginner

    In the simplest of terms, software development decisions for commercial organizations can be reduced to a calculation of whether the cost of developing the software will be outweighed by the estimated revenue generated or costs saved by the software.  However, as Mark Schwartz points out in his book, “The Art of Business Value Paperback” this simple explanation is insufficient for commercial organizations, and not applicable for government and other non-commercial organizations for whom the impact of software isn’t primarily measured in terms of revenue.  

    In this session participants will experience a simulation that has been created to explore these question of how to make decisions about investments to deliver mission and business value by examining the impact of these decisions on the performance of organizations in changing environments.

    Impact mapping is a powerful practice that ensures we are delivering work that directly impacts our business goals and mission objectives.  Our roadmaps and backlogs are usually littered with pet projects, squeaky wheels, and recent ad hoc items that gain priority just because they are the latest shot across our bow.  With a tool such as impact mapping, we can stand firm knowing our real priorities, and fend off these common challengers.

    Impact maps visualize quantifiable benefit that deliverables should produce towards our business objectives.  They allow us to focus our work on those deliverables that move the needle the most, not just deliver features.  The practice is a great way to communicate assumptions, create plans, and align stakeholders as well as aid in strategic planning, roadmap management, and defining quality.  Happily, it is also significantly less bureaucratic and much easier to apply than many alternatives.

    This workshop will provide an appreciation for the power of Impact Mapping and walk you through building your own Impact Maps.  You will learn techniques for creating Impact Maps as well as facilitating an Impact Mapping session.  You will leave the workshop with a usable Impact Map of your current project, or other of your liking, that can bring immediate value to your road-mapping, backlog grooming, and software delivery.

    Talk
    Beginner

    Does your organization find it hard to determine “the right thing” to build? You are not alone – studies show that even in very high performing organizations only 10-35% of initial ideas actually generate business value. Agile development should make it easier to obtain early customer feedback, but in most organizations Agile approaches are limited to software development teams with little connection to the rest of the business. In addition, Agile methods by themselves offer few guidelines on how to translate organizational goals and customer needs into the backlog’s content and relative priorities in the first place. As a result, there is a significant, but often underappreciated risk that Agile teams end up very efficiently building “the wrong thing right.”

    In this session, we explore how Lean Discovery and experimentation can expand the scope of Agile’s “inspect and adapt” feedback loops to systematically identify and validate critical assumptions about our product’s value proposition. Based on the Lean Startup and Lean UX approach to product development as a series of hypotheses about customers’ behaviors and value perceptions, we discuss ways to derive testable assumptions from organizational goals to enable validated learning. Finally, we explore the implications of this approach on project planning and budgeting to support increased business agility.

    Static designs and monolithic structures are brittle and prone to failure. How can we progress beyond them? By understanding the nature of our challenges and applying the right tools at the right time. This talk will describe how to use evolutionary principles to foster changes in your architecture and infrastructure so that you can create antifragile systems.

    Nassim Nicholas Taleb spoke to these ideas in “Antifragile: Things That Gain from Disorder.” Join us as we describe how we can:

    • Move beyond planning for known failure modes and instead develop antifragile systems that are safe-to-fail in unanticipated ways.
    • Leverage the Cynefin framework and its 5 sense-making domains to better frame problems and drive action.
    • Employ microservice architectures to make the variability of our environments work for us, not against us.
    • Gain knowledge more rapidly through multiple parallel experiments.

    When dealing with metrics, most Agile or Lean teams begin with a Burndown Chart.  Unfortunately, that is also where most of them stop.  While a Burndown Chart is a great first step, it only provides a small sliver of the information the team has access to.

     

    In this talk, we’ll be starting at the beginning with what a Cumulative Flow Diagram is, how it relates to a Burndown Chart, its advantages, and where it too ultimately stops.  We’ll then look at additional information radiators that the team can easily use based on existing data to provide transparency to stakeholders and the raw material for continuous improvement.

    DevOps as a buzzword is gaining traction, but what does it really mean? Managers, non-techies, and developers-new-to-devops will get a guided demo of development automation. See all the cool tools in action - continuous integration, automated testing, cloud deployment, etc. More importantly, we'll walk through what they do, and why that adds value to a project. 

    This talk will...

    • Break down the buzzwords and define some key technical practices in plain english.
    • Uncover the pain that leads teams to seek greater automation.
    • Demonstrate a continuous integration pipeline working in practice via live demo.
    • Diminish the knowledge gap between technical practitioners and managers/analysts/coaches.
    • Level-up the vocabulary of non-technical attendees.
    • Introduce practices to developers who don't yet work in an automated environment.
    • Spark "ah-ha" moments to convert skeptics into DevOps believers!

    By the way, all of the tools in the demo are some combination of free and/or open source. DevOps doesn't have to cost a lot.

    Ideas similar to test-infected development or test-driven development have been around quite a while - at least since Alan Perlis wrote about interleaving small amounts of design with small amounts of testing in the 1968 Proceedings of the NATO Software Engineering Conference. Yet, even today, there are endless debates about whether such an approach is useful. Some consider it a baseline practice for any professional developer. Others consider it extra work that adds no value. 

    There's certainly more than one way to achieve a goal. What are the goals, when we write and deliver software professionally? Let's identify the various stakeholders of a software system and enumerate the needs of each. Then, let's walk through several popular ways of building software - TDD and others - and see how we can meet those needs using each approach.

    Charlotte Chang - Software Development Lessons Learned from the Failures of General Motors

    45 mins
    Talk
    Beginner

    In the mid-late 20th century, industry giants asked themselves; “How do we continuously improve?”, “How do we build a quality product?” and “How do we design for end users?” These are the same challenges that we face as software developers and designers today. Issues with technical innovation, resource constraints, and organizational support, are experienced not only in zeros and ones but were experienced on the road. In the early 20th century, the U.S. was considered a global leader in economic and scientific achievement. After those major innovations in transportation, space exploration, and computer science, American industries focused on manufacturing advantages, such as mass production and repeatable use. Progress was now measured by process improvements, adapting to market changes and ability to pivot. Why has the tech industry continued to boom, while other industries struggle? Using examples from General Motors, this talk examines their failures in reliability, collaboration, and product design. Take a step back in history to relive the experiences of these pioneers, learn from their past failures, and how they apply to crafting software products today.

    Talk
    Intermediate

    As timelines on application development and delivery continue to shorten, it’s no longer enough just to ask folks to work faster. Many managers are stuck between missing deadlines or burning out their people.

    This was just one of the challenges for Promontory Interfinancial Network when it chose to implement Agile Portfolio Management over three years ago to speed the deployment of new financial technology software in an IT division of over 80 employees. Since its implementation, the number successful projects has more than doubled and late-stage overload has essentially been eliminated. Along with improving productivity, project visibility, resource allocation, and clarity of prioritization, the process has also been a highlight in audits and examinations as it demonstrates management oversight and risk mitigation.

    In this session, Simon Storm, Senior Director of Enterprise Applications at Promontory, and the project lead in implementing Agile Portfolio Management, shares learnings from the implementation by the IT Management Team. He discusses how to get management buy-in, tips for customizing the Agile process for your institution, and his insights of how spearheading the Agile process can significantly advance your career by putting yourself in the driver’s seat of improving your organization’s productivity and collaboration.

    “Move fast and break things.” — Mark Zuckerberg

    Mobile is no longer a hobby for companies. In that world, speed is the key. My company embraced the principle of “welcoming changing requirements, even late in development.” It’s allowed us to grow, and we have accomplished some amazing things.

    It’s also caused some challenges for teams. They felt the pain of this pace, and our clients were frustrated by delayed releases.

    This presentation describes a 3-month case study I ran to measure things like team communication, productivity, and quality while implementing Scrum for the first time. The results were convincing, and allowed us to learn what happens when you value speed more than anything else.

    I hope you’ll join me in seeing how we learned to work smarter instead of harder.

    A team can’t “become agile” in a vacuum. The “contract” that management and the surrounding organization makes with the team needs to become agile as well in order for the team to be effective. There are 10 commitments that a team's management/stakeholders frequently fail to support fully , even now that agile approaches have arguably become predominant in software development. This presentation enumerates those 10 commitments, and contrasts them with the cheats that organizations typically try to substitute in place of true commitment.

    This workshop is designed for those who feel they are stuck in a rut of designing "death by powerpoint" or "video overload" learning experiences. This facilitated session will provide a simple mechanics, exercise basics and a significant amount of collaboration and feedback centered around designing interactive exercises. The highlight of this session is where teams will design a 5-minute exercise in an iterative fashion, gathering feedback from nearby teams. These techniques will provide useful for those who are put in the position of having a set amount of time to teach a group of participants what's really important about a topic.

    Participants will have the chance to design a five-minute exercise around a Scrum-related topic, first designing a "value proposition" for the exercise, testing it out with another group, making improvements and adjustments, and another test with different groups giving feedback each iteration. The lessons and experiences from this session will have participants walk away with exposure to a number of exercise design topics, plus they will learn a thing or two from fellow attendees by experiencing other team's exercises.
