Problems, problems.
 In the software community we think of
  ourselves, even define ourselves, as
             problem solvers


 But only for certain types of problem
People problems?
      We dismiss people problems:


politics personality clash management


           Identify it. Dismiss it.
So what?
People...
 Commission, Design, Plan, Build, Install,
 Operate, Fix, Support, Choose, Buy, Sell,
        Use, Manage and Pay For
...Software.
But apart from that, they are irrelevant to it.
The right tools for the job
      Technology        People


Abstraction       Simplification
Logic             Intuition
Decompositio      Holism
  n
The trouble is...
Our preference for
                           Over these
   these tools


Abstractio
 n                        Simplification
                          Intuition
Logic                    Holism


Decomp
For example
w does this work?



wo parrots are sitting on a perch. One says
    to the other Can you smell fish?



straction                                Holis
gic                                     Intuiti
Reductionism
               (its a problem)
        I.T. suffers from reductionism
We have all seen the damage this does to
            I.T. departments
    Analyse, categorise, group, standardise,
     commodatise
    Leads to siloed roles, hand-offs, lack of feedback,
     process over people, contracts over collaboration,
     etc.

      So why are we doing it to Agile?
Were forgetting what made Agile
                  work
                Keep the big picture in mind
                Iteration, not incrementalism
          Whole team. Collective code ownership
Organise for the most important thing - people on the proje
          Simplification rather than decomposition




  It is taking us in the wrong direction
For example: stories
De-humanised    Human friendly
Another example:
              iterations
    De-humanised                  Human friendly




                           Only ever a few days from
 much work to comprehend   finished
ation ends ignored        Manageable work load
dom feel done              Genuine want to go for it at
Other examples

uide
 The authors present a set of tools and techniques...
The book places a lot of emphasis on knowing yourself, and understanding how
nteract with others.
 It presents the DISC framework for self- and team-discovery
How does the DISC framework compare to other psychometric tools, such as
Myers-Briggs Type Indicator? If someone knows their MBTI profile how does it m
o the DISC framework you present?
 Our experience is that the majority of the really difficult problems that projects (a
even companies) face are not technology related but rather associated in some w
 o problems with team dynamics, organizational behavior or communication issue
DISC is not the end all-be-all. But it is one component in helping team members
along, understand one another, and modify communication styles to maximize
We have seen this
       before
Reductionism made Waterfall ludicrous
     The tendencies are still there
Agile started with a clean slate, but its
         starting to look messy
   Its not the methodology - Its us
And my point is?
 Agile was successful because it was people friendly, and
        people are critical to software development.
 It gave those of us who are not naturally good at people
          friendly stuff, a people friendly process.
      Agile wont progress unless we remember this
   It needs to progress because it does not always work
    Emphasis on tools is misplaced. It is of secondary
                      importance
People are of primary importance. They make the differenc
