DACI Matrix Instead of RACI
Alvaro Triana, Consultant, Colombia, Member
What I use as an acronym is DACI:
D - Doer,
A - Accountable
C - to be Consulted,
I - to be Informed.
Using the D instead of the R - Responsible, eliminates the confusion between these two roles when using the matrix.
I don´t use more letters in order to keep it simple for the users that participate in using this matrix with me as a consultant....
