SCRUM Overview
Most common agile framework for developing software
Simple to understand, difficult to master
Iterative and incremental
Theory of SCRUM: „The SCRUM Guide“ (19 pages)
Very short definition with strict rules that make the SCRUM what
it is
„Without following the rules, you don’t have SCRUM“
It is expected that other methods, techniques and tools are added
to make the process complete

Planning Poker
Planning Poker
Way of estimating the amount of work needed on a Product Backlog
feature. The feature is described in the form of a user story. Each
estimator (Development team) gives it a value card (e.g. 5 story
points). All cards are revealed at the same time, points are discussed
until consensus is reached and the feature is given a work estimate.

Contracting in Agile Development
Time & Material Contract
Agreement to pay time and resources used. Contract usually states
how many people, for what hourly rate.
Advantages
Flexible contract
Scope is not known upfront,
we can easily add features
and fulfil change requests
Frequent customer
supervision improves trust
Disadvantages
Constant customer
involvement requires extra
time
Difficult to predict final
budget and deadline
Managing the triple
constraint becomes a
continuous mission

When to use SCRUM
Exact requirements are not available upfront
Your team is strong at communication and collaboration
Customer wants to use some form of the product as soon as
possible
