Agile and 'Smoke and Mirrors'
● Agile focuses on Working Software● “Working Software over comprehensive
documentation”● “Working Software is the primary measure of
progress”● “The purpose of each Sprint is to deliver
Increments of potentially releasable functionality”

God Object
● “In OOP, a God Object is an object that knows too much or does too much”

Agile and 'God Object'
● Quality is NOT an after-thought● Code Quality practices

Let's Discuss!

(1) Law of Triviality
● Aka. “Bicycle Shed”● “Members of an organization give
disproportionate weight to trivial issues”● 'Organizational' type

(2) Micromanagement
● “A management style whereby a manager excessively observes or controls the work of subordinates or employees”
● 'Organizational' type

(3) Stovepipe
● Aka. “Silos”● “A stovepipe organization has a structure which
largely restricts the flow of information within the organization to up-down through lines of control, inhibiting or preventing cross-organizational communication”
● 'Organizational' type
16
(4) Premature Optimization
● “Sacrifice of maintainability, in favor of performance optimization, during early stages of design and development”
● 'SW Engineering Methodology' type
17
(5) Overengineering
● “Spending, and effectively wasting, resources making a project more robust and complex than is needed”
● 'Project Management' type
18
(6) Ninety-Ninety Rule
● “Tendency to underestimate the amount of time to complete a project when it is 'nearly done'”
● 'Project Management' type
19
(7) Analysis Paralysis
● “A project stalled in the analysis phase, unable to achieve support for any of the potential plans of approach”
– Generally, “The state of over-analyzing a situation so that a decision or action is never taken”
● 'Organizational' type
20
(8) Mushroom Management
● “The running of a company where the communication channels between the managers and the employees do not work properly. The personnel are not familiar with the ideas or the general state of the company, and are given work without knowing the purpose of this work.”
● 'Organizational' type

(9) Design by Committee
● “A project that has many designers involved but no unifying plan or vision”
● 'Organizational' type
