This paper explores the important question "how the learning entities--individual, group or organisation--are affecting organisational performance". The answer is important for promoting learning and improving performance. This empirical study in the leading power utility in India found that there is a positive relation between individual- and organisational-level learning and organisational performance. However, a direct relation between group-level learning and organisational performance is not strong. It is the organisational-level learning that is critically important to performance. Hence, there is a need for special emphasis by organisations on formal (forms, rules, procedures, policies, technologies, physical structure of the workplace or work processes) and informal (culture, beliefs and paradigms) mechanisms to enhance organisational-level learning, hence performance.
