the Bottleneck in software development

“Walking on water and developing software from a specification are easy if both are frozen” by: Edward V. Berard

Learning is the Bottleneck

What is the goal?

“Build the right thing, right”
  • How do we know what "the right thing" is?
  • Build it twice? ... too expensive
  • Build one small piece at a time, and learn
  • Iterate, and get feedback

Software is like ...      

a manufacturing process
building construction

      no it's not

Software is like ...      

product design process
gardening!

    that's more like it

late project ..

What to do?
“adding manpower to a late software project makes it later”
Fred Brooks in his book The Mythical Man-Month 1975

Agile development methodologies

Challenges

Wrapping up

there is no silver bullet ..

  • There will be failures, use them well
  • Make things visible
  • There will be successes, use them well
  • Agile development exposes the issues that are already there
  • Can you handle the feedback

there is no silver bullet ..

  • We succeed together, or we fail together
  • If you don't trust your team, Agile is not for you
  • Unlearn, Learn, practice, and evolve
  • Be ware of: not enough training
  • Be Agile adopting Agile

Clever Quotes

These guys come in two forms, inline: “The nice thing about standards is that there are so many to choose from” and block:

“For years there has been a theory that millions of monkeys typing at random on millions of typewriters would reproduce the entire works of Shakespeare. The Internet has proven this theory to be untrue.”

Pretty Code

function linkify( selector ) {
                            if( supports3DTransforms ) {

                            var nodes = document.querySelectorAll( selector );

                            for( var i = 0, len = nodes.length; i < len; i++ ) {
                            var node = nodes[i];

                            if( !node.className ) {
                            node.className += ' roll';
                            }
                            }
                            }
                            }
