Mankind or all the creatures of all ages and civilizations can not live without interacting with each other. I mean each one in this life has a particular role to play. Male or female, everyone focuses on the matters or affairs that one was created for. Since Adam and Eve were created they started the role of life, thus Adam could not make anything and all things alone, and so could not Eve. But what is the cooperation itself? It is the practice of individuals or larger societal entities working in common with mutually agreed-upon goals and possibly methods, instead of working separately in competition, and in which the success of one is dependent and contingent upon the success of another. However, co-operation may be coerced (forced) or voluntary (freely chosen), and consequently individuals and groups might co-operate even although they have almost nothing in common qua interests or goals. Examples of that can be found in market trade, military wars, families, workplaces, schools, and prisons, and more generally any institution or organization of which individuals are part (out of their own choice, by law, or forced). Cooperation is the mastermind action that helps to judge success from all angles. The argument is the following: You can not make clapping by one hand. As a haiku goes:   * Heat without cold.   * Happiness without disappointment.   * One hand clap. Here in this subject, the person who can do lots of things in the society is regarded (I mean the society which includes several elements working together.) Hand in hand the world will be ours. Here in our country since Dec.2, 1971, the rulers of the seven Emirates decided to unite this country after the conclusion of the declaration of the Federation among the seven emirates. All the work rose together in all fields starting with the works of improving and uniting the infrastructure and cities building projects and even now the rulers of the emirates still have the attention to cooperate in all the spheres. It means that the person can not live life without helping each other. As we have in Islam several verses of the Holy Quran encourage Moslems to do all the effort and to combine forces for the good things and charity acts, but not cooperate for the war fairs. Projects oblige people to work together, so teamwork has become an essential concept in organizations. Effective teams are a mediator goal towards getting good, sustainable consequences. The industry has seen increasing efforts through thorough training and cross-training to help people to work together more effectively and to accomplish shared goals, whether colleagues are present or absent. We need to listen to other people’s ideas. When people are allowed to freely express their ideas, these initial ideas will produce other ideas.   * We need to ask questions, interact, and discuss the objectives of the team.   * We need to treat others with respect and to support their ideas.   * We need to help our coworkers, which is the general theme of teamwork.   * We need to share with the team to create an environment of teamwork   * All members of the team are encouraged to participate in the team. For a team to work effectively it is essential to team members acquire communication skills and use effective communication channels between one another e.g. using email
