agile principles •Our highest priority is to satisfy the customer through early and continuous delivery of valuable software. •Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage. •Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale. •Business people and developers must work together daily throughout the project. •Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done. •The most efficient and effective method of conveying information to and within a development team is face-to-face conversation. •Working software is the primary measure of progress. •Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely. •Continuous attention to technical excellence and good design enhances agility. •Simplicity—the art of maximizing the amount of work not done—is essential. •The best architectures, requirements, and designs emerge from self-organizing teams. •At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.

team estimates stories, breaking down large ones every 1-4 weeks on cadence, put aside 1-3h prerequisite: user stories derived from goals/backlog product owner verifies capacity and prioritizes work team identifies areas of risk and discusses mitigations iteration planning meetings

dependencies on other teams / systems we don’t know how we will do the work we don’t know if the work will achieve the outcome common risks

user stories Leaky abstractions: http://www.joelonsoftware.com/articles/LeakyAbstractions.html

story list units?

understand if we can achieve our goals identify large/risky work and break down/mitigate grow shared understanding of how work will be done set expectations with stakeholders why estimate?

estimation units • jellybeans • t-shirt sizing • fibonacci • function points • COCOMO predictors • SLIM parameters • beware: relative vs absolute!

try it for a few weeks

the people who made the estimates do the work not a productivity metric! can’t be compared across teams it can be gamed (Goodhart's law) problems with velocity

design vs delivery Product Design and Development Software Delivery (build, testing, deployment) Create new products and services that solve customer problems using hypothesis-driven delivery, modern UX, design thinking. Enable fast flow from development to production and reliable releases by standardizing work, reducing variability and batch sizes. Feature design and implementation may require work that has never been performed before. Integration, test and deployment must be performed continuously as quickly as possible. Estimates are highly uncertain. Cycle times should be well-known and predictable. Outcomes are highly variable. Outcomes should have low variability.

retrospective prime directive “Regardless of what we discover, we understand and truly believe that everyone did the best job they could, given what they knew at the time, their skills and abilities, the resources available, and the situation at hand.” — Norm Kerth
