Alistair’s 3 keys to successful projects:1. Frequent Delivery

of working code2. Access to

customers3. Co-located teams

Efficient Effectivevs. and

The Manifesto1. Our highest priority is to satisfy the customer through early and continuous delivery

of valuable software. 2. Welcome changing requirements, even late in development. Agile processes harness

change for the customer's competitive advantage. 3. Deliver working software frequently, from a couple of weeks to a couple of months,

with a preference to the shorter timescale. 4. Business people and developers must work together daily throughout the project. 5. Build projects around motivated individuals. Give them the environment and support

they need, and trust them to get the job done. 6. The most efficient and effective method of conveying information to and within a

development team is face-to-face conversation. 7. Working software is the primary measure of progress. 8. Agile processes promote sustainable development. The sponsors, developers, and

users should be able to maintain a constant pace indefinitely. 9. Continuous attention to technical excellence and good design enhances agility. 10. Simplicity--the art of maximizing the amount of work not done--is essential. 11. The best architectures, requirements, and designs emerge from self-organizing

teams. 12. At regular intervals, the team reflects on how to become more effective, then tunes

and adjusts its behaviour accordingly.

Effective Leadership

"You cannot hold people responsible for results if you supervise their

methods. You then become responsible for results and rules replace human

judgement, creativity, responsibility“

- Dr. Stephen R. Covey

Effective Leadership

"Effective leaders set up the conditions of empowerment and then... get out of

people’s way, clear their path and become a source of help as

requested.“

- Dr. Stephen R. Covey

Agile in Practice

Size 1 Size 2 Size 3 Size 8

What agile practices did we just witness?

• Iteration Planning• Prioritized backlog (1-

100 not H/M/L)• Manage to Done• Relative estimating• Velocity• Burn up/down• Demo• Retrospectives

• User Stories• Acceptance Testing• Embracing Change• Scope management• Face to face

communication• Kanban / Continuous

Flow• Work in Progress Limits• Continually testing for

failure

In Closing

Want sooner?• Be efficient with

process– (think small)

• Be effective with people
