Role playing is a useful technique for developing a broad understanding of a situation or approach, and to prepare oneself for different eventualities. Role playing can be used to analyse problems from various perspectives, to spark brainstorming sessions, to experiment with different solutions to a problem, to develop team work, and help group problem-solving.
A role play is a vivid way of learning how to handle different situations (KROEHNERT 2007). Role plays also effectively incorporate the principles of Adult Learning Theory. They can clearly show the relevance of the training and enable the trainees to apply the skills they are learning. Trainees share the learning experiences with each other in a supportive environment (BLANCHARD 2007). Furthermore, adults learn more effectively through participative techniques such as role plays.
A role play is a simulation in which each participant is given a role to play. Trainees are given some information related to description of the role, concerns, objectives, responsibilities, emotions, etc. Then, a general description of the situation, and the problem that each one of them faces, is given. For instance, situation could be to propose a new water management system to the beverage industry, managing conflict, bringing different water users to talk to each other, etc. Once the participants read their role descriptions, they act out their roles by interacting with one another.
There are various types of role plays, such as:
Multiple role play – In this type of role play, all trainees are in groups, with each group acting out the role play simultaneously. After the role play, each group analyses the interactions and identifies the learning points.
Single role play – One group of participants plays the role for the rest, providing demonstrations of situation. Other participants observe the role play, analyse their interactions with one another and learn from the play.
Role rotation – It starts as a single role play. After the interaction of participants, the trainer will stop the role play and discuss what happened so far. Then the participants are asked to exchange characters. This method allows a variety of ways to approach the roles.
Spontaneous role play – In this kind of role play, one of the trainees plays herself while the other trainees play people with whom the first participant interacted before.

Role plays are used to help examine real problems on the level of philosophy, emotional response, and physical response. Participants get a chance to analyse situations and try out different theories and tactics in a relatively safe setting. Role plays also enable trainees to understand different people and their roles and to develop insights into the thoughts and feelings of "opponents". Through role plays, participants can identify and anticipate possible problems and reveal fears and anxieties people have about an event or action. Role plays develop group and individual confidence and competence.

In the following, several steps to set up and perform a role play are described. Of course, the set up of role plays can vary.
Role playing is when a group of people act out roles for a particular scenario. As an example, you might train water and sanitation experts by having two people act out a real scenario. One acts as the marketing person for sustainable sanitation. The other acts as the customer. This allows trainee people to practice their marketing techniques. A trainer and/or other trainees may watch the role play and critique it afterwards. Do not forget to plan time for this when designing the sessions.Role plays can be invaluable. They can also be a dreadful torment and waste of time. How you set them up and handle can often make the difference.
