In the context of Business Analysis, how does Gap Analysis differ from Value Stream Mapping when assessing a company's processes?

Gap Analysis looks for the distance between where a company is now and where it wants to be, focusing on missing skills, resources or capabilities that create a performance gap. Value Stream Mapping, on the other hand, draws a detailed picture of every step in a process, showing how materials and information flow from start to finish and highlighting waste or delays. While Gap Analysis asks “what do we lack to reach our goal? ” Value Stream Mapping asks “how does the work actually move and where can it be made faster or cheaper? ” For example, a retailer might use Gap Analysis to find that it needs better inventory data, then use Value Stream Mapping to see that the current ordering process takes too long and creates stockouts.
