PMI-ACP certification exam : formulas to know

Agile Manifesto Values :

If you don’t follow the four Agile Manifesto values “It Will Create Risks” or IWCR:

  • I = Individuals and interactions over processes and tools
  • W = Working software over comprehensive documentation
  • C = Customer collaboration over contract negotiation
  • R = Responding to change over following a plan

Agile Manifesto Principles :

Customer Satisfaction :

  • Satisfy the customer by delivering software that provides value to the customer early, and often.

Welcomed Changes :

  • It is expected that requirements will change and these changes are welcomed.

Frequent Delivery

  • Get working software delivered to the customer as soon as possible.

Collocated Teams

  • Bring the project team and the customers together, preferably collocated in the same physical area.

Motivated Individuals

  • Build your team around motivated individuals and trust them to do the work.

Face-to-Face Contact

  • Face-to-Face communication is the most effective method for exchanging

Working Software

  • True customer value is realized by delivering results, which is represented in
    terms of working software.

Constant Pace

  • Sustain a constant development pace to minimize project team burnout and maximize optimal performance indefinitely.

Continuous Attention

  • Continuous Attention to technical excellence and good design will allow the project team to respond more quickly and easily to change.


  • Maximize the amount of work not done.


  • The team decides how the tasks will be allocated, as opposed to being dictated
    to them.

Regular Reflection

  • Schedule Retrospectives to constantly reflect on the work that was completed and find ways to improve during the next iteration.

Agile Manifesto Principles as Months

January : Just Sit Together (Collocated Teams)

February : Face-to-Face Contact (Face-to-Face Contact)

March : Motivated Individuals (Motivated Individuals)

April : Attention (Continuous Attention)

May : Maintain a Constant Pace (Constant Pace)

June : Jump on Improvements (Regular Reflection)

July : Juggle Changes (Welcomed Changes)

August : Augment Customer Satisfaction (Customer Satisfaction)

September : Simplicity (Simplicity)

October : Organization (Self-Organization)

User Stories

To ensure all user stories are effective, you need to “INVEST”:

 Negotiable

 Estimable
 Small
 Testable

Agile Iteration Events

 Plan each iteration (Iteration Planning)
 Expect daily updates (Daily Stand-Up)
 Examine product results (Iteration Review)
 Reinvent processes for next iteration (Iteration Retrospective)

Formulas :

Internal Rate of Return (IRR) N/A Select project with biggest IRR

Net Present Value (NPV) N/A Select project with biggest NPV

Return on Investment (ROI) N/A Select project with biggest ROI

Schedule Variance (SV) :

SV = EV – PV

< 0 is bad
= 0 is good
> 0 is good

Schedule Performance Index (SPI) :

SPI = EV / PV < 1 is bad
= 1 is good
> 1 is good

Cost Variance (CV):

CV = EV – AC < 0 is bad
= 0 is good
> 0 is good

Cost Performance Index (CPI):


< 1 is bad
= 1 is good
> 1 is good
