Agile Life Cycle Selection

Question 1

Predictive life cycle

Answer 1

A more traditional approach, the bulk of planning occurring upfront then executing in a single pass, sequential process

Fixed requirements, activities performed once, single delivery, goal is to manage cost

Question 2

Iterative life cycle

Answer 2

An approach that allows feedback for unfinished work to improve and modify that work

Dynamic requirements, activities repeated until correct, single delivery, goal is correctness

Question 3

Incremental life cycle

Answer 3

An approach that provides finished deliverables that the customer may be able to use immediately

Dynamic requirements, activities performed once per increment, small deliveries, goal is speed

Question 4

Agile life cycle

Answer 4

An approach that is both iterative and incremental to refine work items and deliver frequently

Dynamic requirements, activities repeated until correct, frequent small delivery, goal is customer value

Question 5

Characteristics of predictive life cycles

Answer 5

Take advantage of high certainty around firm req, stable team and low risk
Team requires detailed plans to know what to deliver and how
Team leaders aim to minimize change
As the team progressed, monitor an control change
Analyze design build test deliver

Question 6

Characteristics of iterative life cycles

Answer 6

Improve the product/result through successive prototypes
Iterations help identify and reduce uncertainty
Benefit when complexity is high, frequent changes occur or scope can change
Analyze -> analyze design (prototype) -> build test (refine) -> deliver

Question 7

Characteristics of incremental life cycles

Answer 7

Can’t wait for everything to be delivered at once, frequent delivery
Team can manage deviations, because delivering value sooner

ADBTD -> ADBTD -> ADBTD -> ADBTD

Question 8

Characteristics of agile life cycles

Answer 8

Two best ways - iteration based agile and flow based agile

Question 9

Iteration based agile

Answer 9

Each timebox is the same size, each time box results in working tested features

Works in iterations to deliver completed features
Team work on most important and collaborates then moves to next

Question 10

Flow based agile

Answer 10

The time it takes to complete a feature is not he same for each feature

Pulls features from backlog based on capacity
Defines workflow with columns and manages the process

Question 11

Characteristics of hybrid life cycles

Answer 11

Combo of any previous life cycles

Example - agile agile agile predictive predictive predictive
Software dev is agile but then rollout is predictive
