performance
In most contexts, 'performance' can be either countable (e.g., "a great performance") or uncountable (e.g., "high performance"), depending on whether you are talking about a specific event or a general level of quality. When used in business or law, the word is more formal and refers to completing duties or contracts rather than acting on a stage. Be careful not to confuse it with 'perform,' which is the verb form. You 'perform' a task to achieve a high 'performance'.
