Top executives believe that culture affects job satisfaction, decision-making style, and communication inside IT. However, culture is typically not something organizations deliberately create — instead, it results as a byproduct of other activities such as the introduction of new management, mergers, and growth. A positive culture improves an organization's performance and the quality of its outputs — a negative one saps them. Positive cultures rely on an organization's clarity of purpose, leadership, communication, and consistent reinforcement of values and norms. Executives should assess their culture profile to test fit with enterprise expectations and make necessary changes to improve the fit.
