5. 4 dimensions
• Great influence to speed, quality and
price
• Each dimension is tightly related
• People – most important, but you
should focus on all at the same time
• Product – the outcome of team work
• Technology – programming language,
architecture, tools, practices
• Process – the way team works
• Environment – great influence, no
control on it

6. SOFTWARE DEVELOPMENT IS
COMPLICATED

7. Product: Domain complexity
• In my 7 year career I worked on 7 different domains.
• Examples of domains:
medical devices, motion picture special effects, biometric
identification, military fighter planes, GIS, commercial airliners, drug
development, warehouse management, banking, finance, oil and gas
exploration, forestry, car production, cell phones, retail companies,
fire safety, smart houses, electric cars, container-ship management,
fishing solutions, elderly people care, etc.

8. Product: Unclear requirements
• You’ll never know what customer wants until the product is completely done.
Picture by Steve McConnell, “Rapid Development” (page 166)
Page 8 IT project management and Scrum, Agnius Paradnikas

9. Product: Software is intangible
• Hard to track progress.
• Hard perceive quality.
• Unclear scope.

10. Technology: Huge variety
• Programming languages: C#, Java, C++, C, PHP, Python, Ruby, F#,
Clojure, JavaScript, Visual Basic, Perl, etc.
• Frameworks: .NET, ASP.NET MVC, Java,
Spring, Zend, Django, Ruby on Rails, etc.
• Platforms: Azure, node.js, Android,
iOS, Windows Phone, etc.

11. Technology: Rapidly changes
• Technology moves very quickly.
• Hard to predict.
• Cloud - no need for hardware infrastructure.
• Software as a Service (SaaS).
• NoSQL.
• JavaScript starts to rule (node.js, meteor.js, Windows 8 apps, etc).
• Mobile first.
• Cross-platform mobile development.
• Responsive Web Design.

12. People: Communication
• Becomes complicated as team grows.
• Essential to sync everyone’s activities.
• <9 need to switch to written documents & formal communication.
Picture by Steve McConnell, “Rapid Development” (page 312)
Page 12 IT project management and Scrum, Agnius Paradnikas

13. People: Motivation
• Critical factor in development speed.
• Hard to grow motivation, easy to destroy.
• If you trying to motivate developer the same way as project manager
– you will fail.
• Top motivators for developers: Achievement, Possibility for growth,
Work itself, Personal life, Technical supervision opportunity.
Page 13 IT project management and Scrum, Agnius Paradnikas

14. People: Productivity
• Developer can be 10x productive than peers.
• Technology and Process may increase productivity drastically.
• Unnecessary meetings kills productivity.

16. Process
• How to make synergy out of chaos?
• Which communication model suits us most?
• Who is responsible for what?
• Who is doing what?
• What is the progress of our work?
• When we will finish?
• How to control quality?
• How to distribute tasks?
• How to avoid overtime at the end of the project?
• What we need to document?
• How we get requirements?
• What are our priorities?
Page 16 IT project management and Scrum, Agnius Paradnikas

17. Waterfall: Grandfather of all processes
• First formal software development process published on 1970.
• Originated from manufacturing and construction industries.
• False assumption that requirements doesn’t change through whole lifecycle.

Page 17 IT project management and Scrum, Agnius Paradnikas

18. Environment
• Great impact.
• Unpredictable.
• Throw away product or adapt.

29. Agile
Agile manifesto 4 main principles:
• Individuals and interactions over processes and tools
• Working software over comprehensive documentation
• Customer collaboration over contract negotiation
• Responding to change over following a plan
Page 29 IT project management and Scrum, Agnius Paradnikas

30. Agile
Twelve Principles of Agile Software
• Our highest priority is to satisfy the customer through early and
continuous delivery of valuable software.
• Welcome changing requirements, even late in development. Agile
processes harness change for the customer's competitive advantage.
• Deliver working software frequently, from a couple of weeks to a
couple of months, with a preference to the shorter timescale.
• Business people and developers must work together daily throughout
the project.
Page 30 IT project management and Scrum, Agnius Paradnikas

31. Agile
Twelve Principles of Agile Software
• Build projects around motivated individuals. Give them the
environment and support they need, and trust them to get the job
done.
• The most efficient and effective method of conveying information to
and within a development team is face-to-face conversation.
• Working software is the primary measure of progress.
• Agile processes promote sustainable development. The sponsors,
developers, and users should be able to maintain a constant pace
indefinitely.
Page 31 IT project management and Scrum, Agnius Paradnikas

32. Agile
Twelve Principles of Agile Software
• Continuous attention to technical excellence and good design
enhances agility.
• Simplicity--the art of maximizing the amount of work not done--is
essential.
• The best architectures, requirements, and designs emerge from self-
organizing teams.
• At regular intervals, the team reflects on how to become more
effective, then tunes and adjusts its behavior accordingly.
