,Scrum in general
Scrum = a framework within which people can address complex adaptive
problems, while productively and creatively delivering products of the highest
possible value.
Empirical process: based on observation and experience, not on theory.
The agile manifesto states the following
- Individuals and interactions over processes and tools
- Working product over comprehensive documentation
- Customer collaboration over contract negotiation
- Responding to change over following a plan
The essence of Scrum is a small team of people. The individual team is highly
flexible and adaptive. These strengths continue operating in single, several,
many, and networks of teams that develop, release, operate and sustain the
work and work products of thousands of people. They collaborate and
interoperate through sophisticated development architectures and target release
environments.
3 pillars of the empirical process
1. Transparency = relevant aspects of the process should be visible for the
stakeholders;
2. Inspection = the results and the process should be inspected continuously
in order to detect unacceptable cases;
3. Adaptation = adaptations should be made to the results as soon as there
is a reason for it.
The scrum team consists of
- One scrum master
- One product owner
- The development team (3-9 developers per team)
The Scrum Master is responsible for promoting and supporting Scrum in an
organization.
The word “development” means in the context of Scrum: Complex work that can
include different aspect dependent on the project.
Practice question 1:
Scrum is based on empirical process control theory. "Transparency" is one of the pillars
of empiricism. What are the two actions that ensure transparency to the product
backlog? (Choose 2 answers)
A. The product Backlog is ordered.
B. The product Backlog only has work for the next 3 sprints.
C. The backlog is signed by de sponsor.
D. The product Backlog is available to all stakeholders.

, Scrum can be applied/ used anywhere.
Scrum has been used to develop software, hardware, embedded software,
networks of interacting function, autonomous vehicles, schools,
government, marketing, managing the operation of organizations and
almost everything we use in our daily lives, as individuals and societies.
Scrum has been used extensively, worldwide, to:
o Research and identify viable markets, technologies, and product
capabilities;
o Develop products and enhancements;
o Release products and enhancements, as frequently as many times
per day;
o Develop and sustain Cloud (online, secure, on-demand) and other
operational environments for product use; and,
o Sustain and renew products.
Total Costs of Ownership = all investments required to conceive, develop,
operate and maintain the product.
The Cone of Uncertainty
The cone of uncertainty can be used to illustrate that, as a forecast lengthens, it
is increasingly less certain. The longer a project will take, the more uncertainty
will emerge.
