45
Q

EVM

A

Earned Value Management (EVM) is a project management technique that measures the technical performance, cost and schedule of a project against planned objectives. The result is a simple set of metrics that provides early warnings of performance issues, allowing for timely and appropriate adjustments. Should be measured at the iteration level because this is where velocity is measured.

46
Q

5 Steps of TDD

A

1) Read, understand and process the feature
2) Translate the requirement by writing a unit test
3) Write and implement the code that fulfills the requirement. Run all the tests
4) Clean up your code by refactoring.
5) Rinse, lather, and repeat.

Test>Code>Refactor>Deliver

47
Q

Relative Sizing

A

Relative estimation is one of the several distinct flavors of estimation used in Agile teams, and consists of estimating tasks or user stories, not separately and in absolute units of time, but by comparison or by grouping of items of equivalent difficulty.

48
Q

Cost Performance Index

A

CPI gives a measure of efficiency. It is calculated by dividing Earned Value by the Actual Cost. CPI > 1 you are under budget.

49
Q

Scheduled Performance Index

A

SPI is calculated by dividing the Planned Value into the Earned Value. SPI > 1 indicates you are ahead of schedule.

50
Q

Schedule Variance

A

Earned Value - Planned Value. SV > 1 indicates you are ahead of schedule.

51
Q

Definition of Ready

A

The Definition of Ready defines the criteria that a specific user story has to meet before being considered for estimation or inclusion into a sprint. Whereas a Definition of Ready is focused on user story level characteristics, the Definition of Done is focused on the sprint or release level.

52
Q

Feature Buffer

A

The customer selects all of the absolutely mandatory work. The estimates for that work are summed. This represents the minimum that can be released. The customer then selects another 25% to 40% more work, selecting toward the higher end of the range for projects with more uncertainty or less tolerance for schedule risk. The estimates for this work are added to the original estimate, resulting in a total estimate for the project. The project is then planned as normal for delivery of the entire set of functionality; however, some amount of the work is optional and will be included only if time permits.

53
Q

DevOps

A

DevOps is the combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity: evolving and improving products at a faster pace than organizations using traditional software development and infrastructure management processes

54
Q

Iteration Planning Time

A

1-2 hours for each week of sprint duration.

55
Q

Force Field Analysis

A

A technique for analyzing the forces that are encouraging and resisting potential or real change and the strength of those forces.

56
Q

Persona

A

57
Q

Product Roadmap

A

A prioritized matrix that describes product features that the team will deliver in each release over time.

58
Q

Exploratory Testing

A

A means of testing that relies on the tester’s autonomy, skill, and creativity in trying to discover issues and unexpected behaviors.

59
Q

Acceptance Criteria

A

An acceptance criterion works per product backlog items (user story) and is defined by the product owner. The done criteria are set for story, iteration or release and defined by the team.

60
Q

Empiricism

A

Empiricism asserts that knowledge comes from experience and making decisions based on what is known.

61
Q

Hardening Iteration

A

A hardening iteration is used for readying the product for production—capturing screenshots for marketing materials, training the help desk, and other small tweaks and final tests that couldn’t be conducted within the regular iterations.

62
Q

Caves and Common

A

The phrase “caves and common” refers to the creation of two zones in the room. The “common” area is organized to maximize osmotic communication and information transfer. The “caves” portion of the room is organized to give people a private place to do e-mail, make phone calls, and take care of their need for separation. For the common area to work well, each team member should be working on one and the same project.

63
Q

Complex Story

A

The complex story is a user story that is inherently large and cannot easily be disaggregated into a set of constituent stories. If a story is complex because of uncertainty associated with it, you may want to split the story into two stories: one investigative and one developing the new feature.

64
Q

Process Tailoring

A

Process tailoring is when a project team takes the organization’s standard process definition and tailors it to the specific needs of their development project.

65
Q

Fist of Five

Q

Graduated Fixed Price Contract

A

Buyer and seller share risk and rewards. There is a higher rate for finishing early, normal rate for on time, and a lower rate for finishing late.

69
Q

Fixed Price Work Packages

A

In this type of contract, as each work package gets completed, the contractor can re-estimate the remaining work packages in the SOW, based on the latest information and risks. This gives the contractor and the customer a realistic estimate of the costs and risks involved in the upcoming work packages and an opportunity to reprioritize the backlog or to decide whether to continue with the rest of the project.

70
Q

Little’s Law

A

Cycle times are proportional to queue lengths. We can predict completion times based on the queue size. L = A x W where L is the number of items inside the queue (WIP), A represents the arrival rate and departure rate of items in and out of the business system or throughput. A = (1 item) / (unit of time) and is displayed as a fraction. W = the amount of time an item spends in the queuing system.

A

A methodology for identifying the most important limiting factor that stands in the way of achieving a goal then systematically improving that constraint until it is no longer the limiting factor.

74
Q

Money for Nothing and Change for Free Contract

A

Contracts that allow for early termination (with a fee) and no charges for changes to scope provided the customer works with the team on every iteration. Changes are free so long as they do not alter the total amount of contracted work.

75
Q

A

The time it would take to complete a given task assuming zero interruptions or unplanned problems.

76
Q

Iteration 0

A

Sets the stage for development efforts. Does not build anything.

77
Q

A

Backlog of work caused by not doing regular cleanup. If not dealt with the cost of development will increase and it will be harder to implement changes. Refactoring is the solution.

78
Q

Escaped Defects

A

Defects that make it to the customer.

79
Q

Kaizen

A

Kaizen is a Japanese business philosophy that focuses on gradually improving productivity by involving all employees and by making the work environment more efficient. Kaizen translates to “change for the better” or “continuous improvement.”
Follows the Plan-Do-Check-Act cycle. Agile uses the Plan>Develop>Evaluate>Learn Cycle.

80
Q

5) Close Retrospective Plus/Delta two columns of what the team can do more or less of.

81
Q

Top-down Estimation

A

Top-down estimating occurs when company management imposes a cost and/or duration on a project, usually without a detailed cost analysis. The estimating process is derived from the opinions of a group of experienced managers, possibly supplemented by outside experts.

82
Q

84
Q

Acceptance Test

A

Acceptance test is a process of verifying that stories were developed such that each works exactly the way the customer expected it to work.

85
Q

Empirical Process Control

A

In empirical process control, you expect the unexpected. With defined process control, every piece of work is understood. Using empirical process control is working in a fact-based, experience-based, and evidence-based manner that control is exercised through visibility, inspection, adaptation.

86
Q

Domain Knowledge

A

Domain knowledge is the subject matter expertise in the business domain of our clients, such as understanding the merchant acquisition process in the payments industry.

87
Q

Process Cycle Efficiency

A

The formula for process cycle efficiency is value-added time divided by total lead time. For instance, if the total lead time for a process is 4 hours and the value-added time equals 1.2 hours, you get a process cycle efficiency of 30 percent – a figure generally viewed as very good.

88
Q

Active Listening Levels

A

1) Internal Listening: Listen to your inner voice
2) Focused Listening: Listen to another person
3) Global Listening: Listening to others in the context of their entire surroundings.

89
Q

Risk Burndown Chart

A

Risk Burndown graphs are very useful Communication Tool for seeing if the total project risk is increasing or decreasing over time. It allows stakeholders to see instantly if we are reducing project risk. Risk burndown graphs show the cumulative risk severities over time.

There are two key pieces of information which the Risk Burndown Graph shows immediately:

Whether the overall level of risk in the project or program is decreasing over time (are we reducing project risk?)
Whether individual risks are increasing in severity over time and whether new risks are being introduced.

90
Q

Agile Team Charter

A

Why are we doing this project? Who benefits and how? What does done look like? How are we going to work together?

97
Q

S-Curve

A

A graph that tracks cost or some other variable against time.

98
Q

Five Focusing Steps of Goldratt’s Theory of Constraints

A

1) Identify the constraint
2) Exploit the constraint
3) Subordinate all other processes to exploit the constraint
4) If after steps 2 and 3 are done, more capacity is needed to meet demand, elevate the constraint
5) If the constraint has not moved go back to step 1, but don’t let complacency become the constraint.
