OK I admit it………..
I like agile…….
But I need to estimate to win work……
My view of agile
Delivers more for less
Uses “lean” principles to maximise “added value” work
Agile project management is an iterative approach
Uses its own language to mark it as “different”
burn down charts
product backlog grooming
spike
velocity
My favourites are
pigs and chickens
scrum
Development Scenarios
Self funded
Less rigour on financials
Penalty if budget exceeded
No direct fiscal risk
Penalty if late
No direct fiscal risk
Reputation risk
Penalty if released incomplete
Loss of market share
Reputational risk
“Won” project
Rigorous on financial management
Penalty if budget exceeded
Direct impact bottom line
Can do long term damage
Penalty if late
Fiscal penalties
Penalty if released incomplete
Fiscal penalties
Will have to complete at own cost
To win a project you must
Give the awarding company an effort, schedule and cost
commitment
This must be estimated
You have to estimate the full effort and schedule required to
deliver the total requirement
Agile will not help you estimate, it could help you be competitive
Transition from estimate to delivery (and back)
Velocity algorithm
Contextualised Metrics
To estimate well I need
Metrics from Agile projects
Complexity
Velocity
Effort
To understand what effort drivers Agile impacts
To understand how total effort will effect sprints
To understand how delivery constraints can be measured and
monitored using velocity
Conclusion
For many projects Agile is a powerful enabling tool for
developers
Software coding is only a small part of delivering a successful
software development project
Measuring (metrics) will help
The developers understand the true velocity within their
microsystem allowing them to advise on total length of project and
accurately estimate time to complete
Will support the bid and proposal process enabling the business
capture team to “right price” opportunities
