Repertorisation is a process of elimination which starts with a broad choice and slowly narrow down the field giving us adequate small group of medicines so that the final selection is made easier with the help of further selection to the material medica.

Repertorisation uses the logic of induction & deduction . The steps starts from casetaking and ends in finding out the similimum.  

1. Case taking
2. Recording & Interpretation
3. Defining the problem
4. Classification & Evaluation of symptom
5. Erecting the totality
6. Selection of repertory & repertorisation proper
7. Repertorial result
8. Analysis & Prescription.

1.CASE TAKING
A successful case taking supplies the physician with all the evidence that is necessary for a proper diagnosis, prognosis & treatment.  For a successful case taking procedure, the doctor has to be competent interviewer and a skillful communicator. General communication skill is necessary to facilitate a better management of the case and to detect & mange difficult situations.  

2. RECORDING & INTERPRETATION
Every case can be a process of learning ,therefore it should be recorded properly.
A good case record should communicate the exact & complete picture of the patient which has been obtained by the physician. It is possible only when the recording is done properly without being hindered by any subjectivity of the physician.
A well maintained clinical record leads to the development of a sound clinical access, furnishes the best possible material for clinical teaching ,research etc. and provide a reliable evidence of ones integrity & efficiency.

3. DEFINING THE PROBLEM
To define a problem means, to define the individual who is facing the problem. Master Hahnemann explained in aphorism 3 " What is to be cured in a disease that is to say in every individual case of the disease ".This is usually deals with the differentiation of the symptoms of the disease from those of the patient. Once the case has been taken properly, it should be interpreted in terms of the subjective sufferings of the patient.

4. CLASSIFICATION & EVALUATION OF SYMPTOM
The classification of symptom means to divide & subdivide them according to the class or group they belong to; they can be classified into common,uncommon,generals particulars etc.
Evaluation means to value symptoms according to their importance & dignity case is full of symptoms of which are all not of same importance & value. Therefore in order to reach the similimum the symptoms have to evaluated accordingly.

5. ERECTING TOTALITY
Totality should be erected according to the facts collected in the case. All the symptoms which are classified and evaluated don’t form a working totality. So the physician has to select a few which can logically represent the whole picture and the logical arrangement must follow a definite principle. 

6. SELECTION OF REPERTORY & REPERTORISATION
The selection of repertory depends upon the type of symptoms selected in a case.
If mental symptoms are prominent _ Kent's repertory may be used
If pathological symptoms " _ Boger's repertory "
If particulars " _ TPB "
Then convert the symptoms in to the rubrics. The symptoms obtained from the patient may not be found in the repertory in the same form, so the physician must know the construction and arrangement of the each repertory. The rubrics should be arranged in hierarchy, referred and worked out in the repertory and a group of medicines with markings are obtained.

7. REPORTORIAL RESULT
A group of close running medicines with marks are obtained after repertorisation.  

8. ANALYSIS & PRESCRIPTION
Reportorial result are to referred with materiamedica. The marks are important but the remedy which get the highest mark not necessarily the final remedy in all the case.
The remedy selected should pass through certain criteria such as succeptibility, sensitivity, suppression, the level of similarity, functional & structural changes, vitality and the miasm to arrive at right potency & dose.
