Software Craftsmen just care about beautiful code

Agile Software Development

We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value:

Individuals and interactions over processes and tools

Working software over comprehensive documentation Customer collaboration over contract negotiation

Responding to change over following a plan

That is, while there is value in the items on the right, we value the items on the left more.

We adopted Agile and now things will be OK

… and the Agile Transformation Era began.

And then we spend 10 year focusing on...

… people, interactions, team building, the ecosystem

Process and Interactions became more important than technical practices

Many Agile projects are now, steadily and iteratively, producing crap mediocre software.

The Agile Hangover

We want to get things done...

… but we are under pressure

The wrong notion of time

But what is to be Agile anyway?

Code quality

Manifesto for Software Craftsmanship raising the bar

As aspiring Software Craftsmen we are raising the bar of professional software development by practising it and helping others learn the craft. Through this

What is Software Craftsmanship?

Software Craftsmanship is all about putting

responsibility, professionalism, pragmatism and pride back into software development

Does context matter? Does it always matter?

How do we know we are building the right thing?

How do we know we are building

the thing right?

Adding value through practice

l  Automated testing l  Test first l  Test-Driven Development l  Pair-programming l  Continuous Integration

Don't discuss practices, discuss value.

Healthy Intolerance

How can you add more value and/or have smaller feedback cycles when not using our

practices?

Mastering the practices is hard …

… and that's why we practice

Perfect practice (narrowing the gap)

Software Craftsmanship is a long journey to mastery

Software Craftsmanship Attitude

- Owning your career - Not a 9 to 5 profession - Practice - Boy scout rule - Expecting promotions

The attitude towards legacy code

Why would we want to be better developers?

Software Craftsmanship Movement - Pragmatic Programmer and Software Craftsmanship books are

published (1999 and 2001) - Dec, 2008: Meeting in US defining a set of principles for Sofware

Software Craftsmanship is not...

… a church, trying to convert all developers

It's about leading by example and showing how we can be better

… about beautiful code

It's about continuously delivering value not writing crap code

Raising the Bar

Stop...

… being miserable and negative … spreading your frustrations

The only way to have people buying into what you believe is if they see you happy.

Craftsmanship is not enough to guarantee the success of a project but the lack of it can be the main cause of its failure

Agile and Craftsmanship complement each other and both are necessary.

Agile processes assume technical excellence and a

professional attitude. Software Craftsmanship takes technical excellence

and professionalism to a whole new level.
