What is Inconsistency management and Types

Definition :

 Inconsistencies are the rule that  violate a consistency rule that links them explicitly or implicitly.

Types of inconsistency

Different types of consistency rule define different types of inconsistency: 

• Terminology clash
• Designation clash 
• Structure clash
• Strong conflict
• Week conflict

Terminology clash

 The same concept is given different names in different statements.  For example, one statement states some condition for 'participating' in a meeting whereas another statement states an apparently similar or related condition for 'attending' a meeting. 

Designation clash

The same name designates different concepts in different statements. For example, one stakeholder interprets 'meeting participation' as full participation until the meeting ends, whereas another interprets it as partial participation. 

Structure clash

The same concept is given different structures in different statements. For example, one statement speaks of a participant's excluded dates as 'a set of time points', whereas another speaks of it as 'a set of time intervals'

Strong conflict

 There are statements that cannot be satisfied when taken together; their logical conjunction evaluates to false in all circumstances. This amounts to classical inconsistency in logic. In our meeting scheduler, there would be a strong conflict between one statement stating that 'the constraints of a participant may not be disclosed to anyone else' and another stating that 'the meeting initiator should know the participants' constraints'. (Those statements might originate from stakeholders having the participant's and initiator's viewpoint, respectively.) 

Weak conflict or divergence. There are statements that are not satisfiable together under some condition. This condition, called a boundary condition, captures a particular combination of circumstances that makes the statements strongly conflicting when it becomes true. The boundary condition must be feasible; that is, it can be made true
