This agile certification is designed to test basic agile knowledge and practices. It follows the Harvard standardized testing techniques for knowledge and practitioner testing, which means if you have knowledge and/or practices Agile you would be able to pass this test.
Who Should Take this Test?
Scrum Masters/Developers/ Business analysts/ Project Managers who are working or planning to work as Scrum Master at Team level in an environment where agile practices are being used to build products.
What you need to know about Agile for Teams?
Agile for Teams or Scrum is a management framework for incremental product development using one or more cross-functional, self-organizing teams of about seven people each. It provides a structure of roles, meetings, rules, and artifacts. Teams are responsible for creating and adapting their processes within this framework. Scrum uses fixed-length iterations, called Sprints, which are typically two weeks or 30 days long. Scrum teams attempt to build a potentially shippable (properly tested) product increment every iteration. An Alternative to Waterfall Scrum’s incremental, iterative approach trades the traditional phases of “waterfall” development for the ability to develop a subset of high-value features first, incorporating feedback sooner.
The greatest potential benefit of Scrum is for complex work involving knowledge creation and collaboration, such as new product development. Scrum is usually associated with object-oriented software development. Its use has also spread to the development of products such as semiconductors, mortgages, and wheelchairs.
Doing Scrum, or Pretending to Do Scrum?
Scrum’s relentless reality checks expose dysfunctional constraints in individuals, teams, and organizations. Many people claiming to do Scrum modify the parts that require breaking through organizational impediments and end up robbing themselves of most of the benefits
- Single person responsible for maximizing the return on investment (ROI) of the development effort
- Responsible for product vision
- Constantly re-prioritizes the Product Backlog, adjusting any long term expectations such as release plans
- Accepts or rejects each product increment
- Decides whether to ship
- Decides whether to continue development
- Considers stakeholder interests
- May contribute as a team member
- Has a leadership role
Scrum Development Team
- Cross-functional (e.g., includes members with testing skills, and often others not traditionally called developers: business analysts, domain experts, etc.)
- Self-organizing / self-managing, without externally assigned roles
- Negotiates commitments with the Product Owner, one Sprint at a time
- Has autonomy regarding how to reach commitments
- Intensely collaborative
- Most successful when located in one team room, particularly for the first few Sprints
- Most successful with long-term, full-time membership. Scrum moves work to a flexible learning team and avoids moving people or splitting them between teams.
- 7 ± 2 members
- Has a leadership role
- Facilitates the Scrum process
- Facilitates the Scrum process
- Creates an environment conducive to team self-organization
- Captures empirical data to adjust forecasts
- Shields the team from external interference and distractions to keep it in group flow (a.k.a. the zone)
- Enforces timeboxes
- Keeps Scrum artifacts visible
- Promotes improved engineering practices
- Has no management authority over the team (anyone with authority over the team is by definition not its Scrum Master)
- Has a leadership role
All Scrum Meetings are facilitated by the Scrum Master, who has no decision-making authority at these meetings.
Sprint Planning Meeting
At the beginning of each Sprint, the Product Owner and team hold a Sprint Planning Meeting to negotiate which Product Backlog Items they will attempt to convert to working product during the Sprint. The Product Owner is responsible for declaring which items are the most important to the business. The team is responsible for selecting the amount of work they feel they can implement without accruing technical debt. The team “pulls” work from the Product Backlog to the Sprint Backlog.
When teams are given complex work that has inherent uncertainty, they must work together to intuitively gauge their capacity to commit to items, while learning from previous Sprints. Planning their hourly capacity and comparing their estimates to actuals makes the team pretend to be precise and reduces ownership of their commitments. Unless the work is truly predictable, they should discard such practices within the first few Sprints or avoid them altogether.
Until a team has learned how to complete a potentially-shippable product increment each Sprint, it should reduce the amount of functionality it commits to. Failure to change old habits leads to technical debt and eventual design death, as shown in Figure 15.
If the top of the Product Backlog has not been refined, a major portion of the planning meeting should be spent doing this, as described in the Backlog Refinement Meeting section.
Toward the end of the Sprint Planning Meeting, the team breaks the selected items into an initial list of Sprint Tasks, and makes a final commitment to do the work. The maximum allotted time (a.k.a. timebox) for planning a 30-day Sprint is eight hours, reduced proportionally for a shorter Sprint.
Daily Scrum and Sprint Execution
Every day at the same time and place, the Scrum Development Team members spend a total of 15 minutes reporting to each other. Each team member summarizes what he did the previous day, what he will do today, and what impediments he faces.
Standing up at the Daily Scrum will help keep it short. Topics that require additional attention may be discussed by whomever is interested after every team member has reported.
The team may find it useful to maintain a current Sprint Task List, a Sprint Burndown Chart, and an Impediments List. During Sprint execution it is common to discover additional tasks necessary to achieve the Sprint goals. Impediments caused by issues beyond the team’s control are considered organizational impediments.
It is almost always useful for the Product Owner to attend the Daily Scrum. But when any attendee also happens to be the team’s boss, the invisible gun effect hampers self-organization and emergent leadership. People lacking real experience of team self-organization won’t see this problem, just as fish are unaware of water. Conversely, a team that needs additional expertise in product requirements will benefit from increased Product Owner involvement, including Daily Scrum attendance.
The Daily Scrum is intended to disrupt old habits of working separately. Members should remain vigilant for signs of the old approach. For example, looking only at the Scrum aster when
speaking is one symptom that the team hasn’t learned to operate as a self-organizing entity.
Sprint Review Meeting
After Sprint execution, the team holds a Sprint Review Meeting to demonstrate a working product increment to the Product Owner and everyone else who is interested.
The meeting should feature a live demonstration, not a report. After the demonstration, the Product Owner reviews the commitments made at the Sprint Planning Meeting and declares which items he now considers done. For example, a software item that is merely “code complete” is considered not done, because untested software isn’t shippable. Incomplete items are returned to the Product Backlog and ranked according to the Product Owner’s revised priorities as candidates for future Sprints.
The Scrum Master helps the Product Owner and stakeholders convert their feedback to new Product Backlog Items for prioritization by the Product Owner. Often, new scope discovery outpaces the team’s rate of development. If the Product Owner feels that the newly discovered scope is more important than the original expectations, new scope displaces old scope in the Product Backlog.
The Sprint Review Meeting is the appropriate meeting for external stakeholders (even end users) to attend. It is the opportunity to inspect and adapt the product as it emerges, and iteratively refine everyone’s understanding of the requirements. New products, particularly software products, are hard to visualize in a vacuum. Many customers
need to be able to react to a piece of functioning software to discover what they will actually want. Iterative development, a value-driven approach, allows the creation of products that couldn’t have been specified up front in a plan-driven approach.
Sprint Retrospective Meeting
Each Sprint ends with a retrospective. At this meeting, the team reflects on its own process. They inspect their behavior and take action to adapt it for future Sprints. Dedicated Scrum Masters will find alternatives to the stale, fearful meetings everyone has come to expect. An in-depth retrospective requires an environment of psychological safety not found in most
organizations. Without safety, the retrospective discussion will either avoid the uncomfortable issues or deteriorate into blaming and hostility.
A common impediment to full transparency on the team is the presence of people who conduct performance appraisals.
Another impediment to an insightful retrospective is the human tendency to jump to conclusions and propose actions too quickly. Agile Retrospectives, the most popular book on this topic, describes a series of steps to slow this process down: Set the stage, gather data, generate insights, decide what to do, close the retrospective.1 Another guide recommended for Scrum Masters, The Art of Focused Conversations, breaks the process into similar steps: Objective, reflective, interpretive, and decisional (ORID).2
A third impediment to psychological safety is geographic distribution. Geographically dispersed teams usually do not collaborate as well as those in team rooms. Retrospectives often expose organizational impediments. Once a team has resolved the impediments within its immediate influence, the Scrum Master should work to expand that influence, chipping away at
the organizational impediments.
Scrum Masters should use a variety of techniques to facilitate retrospectives, including silent writing, timelines, and satisfaction histograms. In all cases, the goals are to gain a common understanding of multiple perspectives and to develop actions that will take the team to the next level.
Backlog Refinement Meeting
Most Product Backlog Items (PBIs) initially need refinement because they are too large and poorly understood. Teams have found it useful to take a little time out of Sprint Execution — every Sprint — to help prepare the Product Backlog for the next Sprint Planning Meeting.
In the Backlog Refinement Meeting, the team estimates the amount of effort they would expend to complete items in the Product Backlog and provides other technical information to help the Product Owner prioritize them.3 Large vague items are split and clarified, considering both business and technical concerns. Sometimes a subset of the team, in conjunction with the Product Owner and other stakeholders, will compose and split Product Backlog Items before involving the entire team in estimation.
A skilled Scrum Master can help the team identify thin vertical slices of work that still have business value, while promoting a rigorous definition of “done” that includes proper testing and refactoring.
It is common to write Product Backlog Items in User Story form.4 In this approach, oversized PBIs are called epics. Traditional development breaks features into horizontal tasks (resembling waterfall phases) that cannot be prioritized independently and lack business value from the customer’s perspective. This habit is hard to break.
Agility requires learning to split large epics into user stories representing very small product features. For example, in a medical records application the epic “display the entire contents of a patient’s allergy records to a doctor” yielded the story “display whether or not any allergy records exist.” While the engineers anticipated significant technical challenges in parsing the internal aspects of the allergy records, the presence or absence of any allergy was the most important thing the doctors needed to know. Collaboration between business people and technical people to split this epic yielded a story representing 80% of the business value for 20% of the effort of the original epic.
Since most customers don’t use most features of most products, it’s wise to split epics to deliver the most valuable stories first. While delivering lower-value features later is likely to involve some rework, rework is better than no work.
The Backlog Refinement Meeting lacks an official name and has also been called “Backlog Grooming,” “Backlog Maintenance,” or “Story Time.”
- Force-ranked list of desired functionality
- Visible to all stakeholders
- Any stakeholder (including the Team) can add items
- Constantly re-prioritized by the Product Owner
- Items at top are more granular than items at bottom
- Maintained during the Backlog Refinement Meeting
Product Backlog Item (PBI)
- Specifies the what more than the how of a customer-centric feature
- Often written in User Story form
- Has a product-wide definition of done to prevent technical debt
- May have item-specific acceptance criteria
- Effort is estimated by the team, ideally in relative units (e.g., story
- Effort is roughly 2-3 people 2-3 days, or smaller for advanced teams
- Consists of committed PBIs negotiated between the team and the Product Owner during the Sprint Planning Meeting
- Scope commitment is fixed during Sprint Execution
- Initial tasks are identified by the team during Sprint Planning Meeting
- Team will discover additional tasks needed to meet the fixed scope commitment during Sprint execution
- Visible to the team
- Referenced during the Daily Scrum Meeting
- Specifies how to achieve the PBI’s what
- Requires one day or less of work
- Remaining effort is re-estimated daily, typically in hours
- During Sprint Execution, a point person may volunteer to be primarily responsible for a task
- Owned by the entire team; collaboration is expected
Sprint Burndown Chart
- Owned by the entire team; collaboration is expected
- Indicates total remaining team task hours within one Sprint
- Re-estimated daily, thus may go up before going down
- Intended to facilitate team self-organization
- Fancy variations, such as itemizing by point person or adding trend lines, tend to reduce effectiveness at encouraging collaboration
- Seemed like a good idea in the early days of Scrum, but in practice has often been misused as a management report, inviting intervention. The Scrum Master should discontinue use of this chart if it becomes an impediment to team self-organization.
Product / Release Burndown Chart
- Tracks the remaining Product Backlog effort from one Sprint to the next
- May use relative units such as Story Points for Y axis
- Depicts historical trends to adjust forecasts
