explain IFRS 15 Revenue From Contracts With Customers fifth principles?

Step 5: Recognise revenue when (or as) the entity satisfies a performance obligation—an entity recognises revenue when (or as) it satisfies a performance obligation by transferring a promised good or service to a customer (which is when the customer obtains control of that good or service). The amount of revenue recognised is the amount allocated to the satisfied performance obligation. A performance obligation may be satisfied at a point in time (typically for promises to transfer goods to a customer) or over time (typically for promises to transfer services to a customer). For performance obligations satisfied over time, an entity recognises revenue over time by selecting an appropriate method for measuring the entity’s progress towards complete satisfaction of that performance obligation.
