21st Century Software Delivery

For many years software engineering meant delivering software the way we constructed buildings. This turns out to be a wildly inefficient way to create innovative products and services based on software. In this talk I’ll discuss what makes software different from buildings, and how we can take advantage of its unique properties to satisfy our customers through continuously delivery of valuable software. I’ll also talk about how you can adopt these practices in the safety of your own office, and explore the art of the possible and the patterns and practices used by high performing companies.

   Shareholder value is the dumbest idea in the
   world … [it is] a result, not a strategy … Your main
   constituencies are your employees, your
   customers and your products.

11. His parents, he says, never really answered any of the
    questions they had. Go figure it out for yourself, they
    would say. “I got really into the scientific method of
    developing a hypothesis and testing it and getting a result
    and going back to do it again.”

    “Instead of arguing about new software ideas, we actually tried
    them out by writing quick prototypes, keeping the ideas that
    worked best and discarding the others. We always had something
    running that represented our best thinking at the time.”

19. hypothesis-driven delivery
    We believe that
    [building this feature]
    [for these people]
    will achieve [this outcome].
    We will know we are successful when we see
    [this signal from the market].

30. what is culture?
    “A pattern of shared tacit assumptions that was learned by a
    group as it solved its problems of external adaptation and
    internal integration, that has worked well enough to be
    considered valid and, therefore, to be taught to new members as
    the correct way to perceive, think, and feel in relation to those
    problems.”
    — Edgar Schein, The Corporate Culture Survival Guide

31. what is culture?
    “Our true culture is made primarily of the things no one will say...
    Culture is about power dynamics, unspoken priorities and
    beliefs, mythologies, conflicts, enforcement of social norms,
    creation of in/out groups and distribution of wealth and control
    inside companies.”

33. “I think building this culture is the key to innovation. Creativity
    must flow from everywhere. Whether you are a summer intern
    or the CTO, any good idea must be able to seek an objective
    test, preferably a test that exposes the idea to real customers.
    Everyone must be able to experiment, learn, and iterate.”
