Strengths There are many benefits of doing an ACH matrix  : It is auditable , it is widely believed to help overcome cognitive biases, though there is a lack of strong empirical evidence to support this belief , since the ACH requires the analyst to construct a matrix, the evidence and hypotheses can be backtracked , this allows the decisionmaker or other analysts to see the sequence of rules and data that led to the conclusion. Weaknesses There are several weaknesses of doing an ACH matrix  : The process to create an ACH is time consuming , The ACH matrix can be problematic when analyzing a complex project , It can be cumbersome for an analyst to manage a large database with multiple pieces of evidence , evidence also presents a problem if it is unreliable , the evidence used in the matrix is static and therefore it can be a snapshot in time. Automation A few online and downloadable  tools help automate the ACH process. These programs leave a visual trail of evidence and allow the analyst to weigh evidence : PARC ACH 2.0 was developed by Palo Alto Research Center (PARC) in collaboration with Richards J. Heuer, Jr. It is a standard ACH program that allows analysts to enter evidence and rate its credibility and relevance. Decision Command software  created by Dr. Willard Zangwill. DECIDE was developed by the analytic research firm SSS Research, Inc. . DECIDE not only allows analysts to manipulate ACH, but it provides multiple visualization products.
