If Contingency is required:

1- Focus on the
Business Need

2- Deliver on
Time

3- Collaborate

Agile Project Management

•
•
•
•

Understand the true business priorities
Establish a sound business case
Seek continuous business sponsorship and commitment
Guarantee the minimum usable subset

• Timebox the work
• Focus on business priorities (MoSCoW)
• Always hit deadlines
• Involve the right stakeholders at the right time
• Ensure that the members of the team are empowered to take
decisions on behalf those they represent
• Actively involve the Business Representatives
• Build a one-team culture

5/22

4- Never
compromise
Quality

5- Build
incrementally
from firm
Foundations

• Strive for early delivery of business benefit
• Continually confirm the correct solution is being built
• Formally re-assess priorities and on-going project viability

6- Develop
iteratively

•
•
•
•
•
•

Set the level of quality at the outset
Ensure that quality does not become a variable
Design, document and test appropriately
Build in quality by constant review
Test early and continuously

Do Enough Design up Front (EDUF)*
Take an iterative approach to building all products
Build customer feedback into each iteration
Accept that most detail emerges later rather than sooner
Embrace change
Be creative, experiment, learn and evolve

*Enough Design up Front (EDUF) instead of :
Big Design up Front (BDUF): Traditional projects, lack of flexibility or creativity
No Design up Front (NDUF): Other Agile approaches, too risky in complex structures
6/22
Principles III

Agile Project Management

• Run daily team stand-up* sessions
• Use facilitated workshops
7- Communicate • Use rich communication techniques such as modelling and
prototyping
continuously and
• Present instances of the evolving solution early and often
clearly
• Keep documentation lean and timely
• Manage stakeholders expectations throughout the project
• Encourage informal face to face communication at all levels

8- Demonstrate
control

• Use an appropriate level of formality for tracking and reporting
• Make plans and progress visible to all
• Measure progress through focus on delivery of products rather than
completed activities
• Manage proactively
• Evaluate continuing project viability based on the business
objectives

*The Daily Stand-up:
Each team member in turn describes:
• What they have been doing since the last Stand-up
• What they will be doing between now and the next Stand-up
• Any problems, risks or issues
Short and fixed duration (15 minutes)

(this time)

Agile Project Management

Maximum 60% of total effort
Worst Case, Minimum Usable Subset (based on anticipated benefit)
Cannot deliver without this
No point delivering on target date without this
What happens if this requirement is not met? ‘Cancel the project’
Maximum 20% of total effort
Expected Case
Important but not vital
May be painful to leave out, but the solution is still viable
May need some kind of workaround
Maximum 20% of total effort
Best Case
Wanted / desirable but less important
Less impact if left out (compare with a should have)

Agreed these requirements will not be delivered
Recorded in PRL

80% of the solution can be produced in 20% of the time that it would take to produce the
total solution

Measurements

Business Value
(or outcome)

Agile Project Management

Earned Value Analysis (EVA). Measure the value that has been ‘earned’ to date in
the project (on the product/result/service).

Output

Used to define the objectives for the Timeboxes (deliverables).

Quality

Number of defects.

Effort and delivery The effort of a timebox is fixed and it is expected to deliver a number of
prioritised features.
speed (velocity)
Cost

The Business Case is based on the balance between cost and business value.

18/22
Quality

Agile Project Management

Not 100% but still a quality solution

The quality is judged on whether the solution contains at least the
Minimum Usable Subset (60% solution) and whether all delivered
requirements meet the agreed standard.
Maintainability
Level 1

Maintainability is a required attribute of the initial delivered solution

Level 2

Deliver first, re-engineer later

Level 3

Short term, tactical solution

Risks I

Agile Project Management

Risks to successful Atern
Low or patchy
availability of
Business roles

Having a fully
detailed specification

In the early lifecycle phases, define and agree the level of commitment needed.

Try to introduce the concept of Iterative Development and Enough Design Up
Front (EDUF) before time and effort is spent producing this detailed
specification.

Expecting the 100%
solution

Atern’s approach is based around the idea that Time, Cost and Quality are fixed
and contingency is built around the prioritisation of Features. The best case is to
deliver the 100% solution.

Swapping resources
in and out of the
team

Try to ring-fence the team for the duration of the project. Atern’s small teams
and the use of rich communication means that a lot of the team information is
known and shared informally, rather than being formally written down.

21/22
Risks II

Agile Project Management

How Atern reduces risks
The business don’t
know exactly what
they want

This is seen as normal as the detail emerges through ‘Iterative Development’.

The business change
their minds

Change is seen as a fact of life and is encompassed within the Timebox and
MoSCoW prioritisation process.

Not having all the
detail agreed at the
start

Atern’s principle of ‘Build from Firm Foundations’ ensures Enough Design Up
Front (EDUF) is done to move the project safely forward.

Unwillingness to
commit to final signoff

Using Atern’s Timeboxes the business accepts the evolving solution
incrementally.

Late delivery

The whole Atern approach is designed to deliver the right solution on time.
