Precedence Diagram - Resolving Prior Problems in Precedence Order
Precedence diagram is a method of getting lots of problems by brainstorming, and resolving prior problems in precedence order.
What is Precedence Diagram
The theory of Precedence Diagram is to connect work process with key targets, AKA: Core Success
Factor (CSF). Typical factors of CSF include price, quality, features, reputation,
etc. that complete a product or service. If you ask yourself: "What is the most
important value of our enterprise in customers' eyes? " The answer is usually
the Core Success Factor.
Advantages of Precedence Diagram
Three main advantages of Precedence matrix Diagram are:
- An effective method of judging main bottleneck, which might have already
seriously hindered improvement of main targets.
- A possibility of providing precedence order, so that resources can be
allocated to promote process.
- A unity method helpful for managerial team to support precedence
consensus from all departments.
Application of Precedence Diagram
The purpose of Precedence Matrix is to help people to decide project
precedence according to weight and decisive relevance. Once we recognize the
relevance and options via Relationship Matrix, Association Diagram, Tree Diagram
etc., we'll enter into decision-making stage.
Two factors are needed in Precedence Diagram:
(1) Decision-making principles,
depending on our understanding of important matters. e.g.: Economy, time,
physical performance and service form made up basic catalogues of
(2) Comparative method in relevance. Evaluation can be subjective or
In subjective evaluation, with everyone's past experience and understanding
of future, they collectively follow agreeing / voting / basic queuing process.
Method includes Delphli method--sequence / voting plan, Nominal Group Technique
(NGT) and so on.
In objective evaluation, we specify relevant weight value and calculate this
values to a relatively prior number. The Analytic Hierarchy process (AHP) is a
widely used quantification technique.
