Five Steps of Risk Management

Overview of Risk Management Process

**

• The five steps include:

• Risk Identification

• Risk Analysis

• Ranking Risks

• Treating Risks

Risk Management and Scrum Practices

Understanding Risk Analysis

• Identifying risks in a company's operating environment is crucial; once identified, risks must be analyzed.

• Risks should be ranked and prioritized since not all risks carry the same weight; this helps determine which risks to address first.

• The process of treating risks involves consulting experts to avoid or reduce them effectively.

• A final review stage ensures that identified risks have been adequately addressed and evaluated.

Time Boxing in Scrum

• Time boxing refers to allocating a fixed amount of time for specific activities, with a maximum duration of 15 minutes for each session.

• Only the product owner has the authority to cancel a Sprint before its time box limit ends.

Managing Scope Creep

• To manage scope creep, implement a change control mechanism that includes maintaining baseline scope and tracking project progress against it.

• Variance analysis is essential for identifying discrepancies between current project status and original plans, allowing teams to assess severity and sources of changes.

• Teams should decide on preventive or corrective actions based on change requests, managing these through integrated change control methods.

Role of the Scrum Master

• A workshop facilitator (Scrum Master) must remain objective during discussions without contributing personal opinions while assisting the team towards optimal results.

Engaging Stakeholders in Scrum Meetings

• Successful projects depend on effective coordination between business stakeholders and developers; daily standup meetings are vital for this engagement.

• The purpose of daily scrums is to assess progress toward Sprint goals, ensuring all team members are aligned.

Structure of Effective User Stories

• Good user stories should clarify who the users are, what is being built, why it's being built, and what value it brings to users.

• Well-crafted stories adhere to Bill Vick's INVEST criteria: Independent, Negotiable, Valuable, Estimable, Small, Testable.

Sprint Retrospectives

• In Sprint retrospectives, the Scrum Master facilitates discussions about previous improvements while inspecting new ones for adaptation.

Ensuring Timely Delivery of Action Items

• Regular retrospectives help ensure timely delivery by identifying action items; some organizations use trackers for monitoring these items effectively.

Concept of Sprints in Scrum
