Affinity Estimation

A method used to quickly place user stories into a comparable-sized group.

eXtreme Programming (XP)

A methodology in Agile with one-week iterations and paired development. It focuses on communication, simplicity (easier to draw a diagram instead of writing code), feedback (through diagrams to quickly gain feedback), courage (make decisions and changes by discarding or refactoring), and humility (we don't know everything).

Agile Manifesto: Simplicity

Allows team members to focus on what is necessary to achieve the requirements needed to create and deliver value to the project and customer.

Agile Principles

(1) Customer satisfaction through early and continuous delivery of valuable software. (highest priority). (2) Welcome change. (3) Deliver working software frequently. (4) Business people and developers must work together and daily throughout the project. (5) Build project around motivated individuals. (6) Favor face-to-face communication. (7) Working software is the primary measure of progress. (8) Promotes sustainable development. (9) Continuous attention to technical excellence. (10) Simplicity (the art of maximizing the work not done) is essential. (11) The best architectures, requirements and design emerge from self-organizing teams. (12) At regular intervals, the team reflects on how to become more effective and adjusts its behavior accordingly.

Agile Values and Principles

- Adopt a formal agile approach, designed and proved to achieve desired results. - Implement changes to project practices in a manner that fits the project context to achieve progress on a core value or principle.

Cancelling a Sprint

- Product Owner has the authority to do this. - It can happen when the Sprint Goal becomes obsolete (changes in Product Backlog, strategies, or approach). - When it happens, the items that are "done" will be reviewed and accepted, and the rest of the items will be put back into the Product Backlog. - It is very unusual.

Agile Manifesto

-Individuals and interactions (most important) over process and tools. -Working software over comprehensive documentation. The idea is that software adds value for the business need, but there is no value in documentation. Excessive documentation is waste. -Customer collaboration over contract negotiation.

Three Scrum Pillars

Transparency, Inspection, and Adaptation (TIA)

Industrial projects

Visible, stable, running things, structure, correct answers, task driven, command and control, standards, performance measurement, cost of workers for a task.

Preferred approach for candidate user stories, also known as story writing workshops. It optimizes the workflow by understanding user needs, and engage stakeholders in the design process.

What are User story workshops?

Candidate stories

What are potential stories called?

These are also known as innovation games, and some examples are: - Remember the future - Prune the product tree - Speed boat - Buy a feature - Bang for the buck

What are some collaboration games?

- Vision Statement - Product Roadmap - Stories (typically done by Product Owner) - Product Backlog

What are some of the pre-sprint activities?

- Spring planning - Daily Scrum - Sprint Review - Sprint Retrospective

What are the four formal events for inspection and adaptation prescribed in Scrum?

- What has your team done since we last met? - What will your team do before our next meeting? - Are there any roadblocks in your team's way? - Will your team put anything in another team's way?

What are the four questions answered during a Scrum of scrums meetings?

- Predictive Life Cycle - Agile Life Cycle - Iterative Life Cycle (correctness of the solution) - Incremental Life Cycle

What are the four types of life cycles?

Card (identify the story), Conversation (details) and Confirmation (confirmed the story)

What are the three C's of user stories?

- Who was asking for this? - Why are we doing this?

What are two questions for creating a user story?

Hosting workshops - where people get together to get the same kind of work done. It is facilitated for involvement.

What can you do to gather requirements?

- More risk is introduced. Risk of being disconnected from stakeholders. - It will take longer to go to market with a product release. - Frequency that team composition can be changed. - All sprints should be of same duration.

What happens if a Sprint lasts longer than 2-4 weeks?

It is a framework for processes, not a process itself. It evolved since the 1990s, and it is a characteristic of product management, not just project management.

What is Scrum?

The development team selects appropriate number of items from the top of the product backlog, and puts them in the sprint backlog. They estimate the effort for the stories, so that the selected stories equate their capacity.

What is the role of the development team in a sprint?

The product owner is responsible for ranking and ordering the product backlog. The product owner also needs to make sure that user stories are easy to understand.

What is the role of the product owner in a sprint?

When there are serious or many impediments the scrum master needs to: - Alert management to the impediments and impact - Consult with the Development Team - Prioritizing the impediments list and address each in order

What should the scrum master do when facing impediments?

Personnel Loss

When an employer faces the loss of a human resource through death, injury, or disability of an employee.

Swarming

When the team collaborates to focus on a single user story.
