Process models are processes of the exact same nature that are categorized together into a model. Therefore, a procedure model is a description of a process at the kind level. Since the process model is at the kind level, a procedure is an instantiation of it. The exact same process model is used repetitively for the development of many applications and therefore, has many instantiations. One possible use of a procedure model is to suggest how things must/should/could be performed in contrast to the procedure itself which is truly exactly what occurs. A procedure model is about an anticipation of exactly what the process will look like. Exactly what the procedure shall be will be determined during actual system development.

The objectives of a process model are to be:

* Descriptive
o Track exactly what really happens during a procedure.
o Takes the viewpoint of an external observer who takes a look at the means a process has been done and determines the improvements that have to be made to make it carry out better or successfully.

* Prescriptive
o Defines the desired processes and how they should/could/might be performed.
o Sets rules, guidelines, and behavior patterns which, if followed, would result in the desired process efficiency. They can vary from rigorous enforcement to flexible support.

* Explanatory
o Provides explanations about the rationale of processes.
o Explore and assess the numerous possible courses of action based upon reasonable arguments.
o Establish an explicit link between processes and the requirements that the model should satisfy.
o Pre-defines points at which information can be removed for reporting functions.

As the quality of procedure models is being discussed in this paper, there is a should elaborate quality of modelling methods as an important essence in quality of process models. In most existing structure produced for comprehending the quality, the line between quality of modeling strategies and the quality of models as an outcome of the application of those methods are not clearly drawn. This report will focus both on quality of procedure modelling methods and quality of process models in order to plainly distinguish the 2.

Various frameworks were established to assist in understanding quality of procedure modelling methods, one example is Quality based modelling examination structure or referred to as Q-Me framework which argued to offer set of well defined quality homes and treatments to make an unbiased assessment of this residential properties possible. This framework also has advantages of offering consistent and official description of the model element within one or different model kinds utilizing one modelling strategies Basically this can make evaluation of both the product quality and the procedure quality of modelling techniques with regard to a set of properties that have been defined in the past.

Quality residential properties that associate with company process modelling methods discussed in. are:

Expressiveness- the degree to which a provided modelling technique can signifying the models of any number and kinds of application domains.

Arbitrariness- the degree of liberty one has when modelling one and the exact same domain

Suitability-the degree to which a provided modelling strategy is specifically tailored for a certain kind of application domain.

Coherence- the ease with which the method of working and way of modelling are understood by participants.

Coherencethe degree to which the specific sub models of a means of modelling constitutes a whole.

Completeness the degree to which all essential principles of the application domain are represented in the method of modelling.

Effectiveness- the degree to which the modelling procedure utilises resources such as time and individuals.

Efficiency- the degree to which the modelling procedure accomplishes its goal.
