Data Mapping Effort at 35% complexity and validation allowance: a worked example

Push complexity and validation allowance up to 35% and the picture changes. This example computes every intermediate figure at that operating point. Use this calculator when estimating the effort for mapping source fields to target fields between ERP, MES, PLM, or other manufacturing systems during an integration or migration project.

The inputs for this scenario

  • Source-to-target data fields to map: 150 fields (unchanged)
  • Analyst mapping throughput: 6 fields / hour (unchanged)
  • Complexity and validation allowance: 35 % (raised for this scenario; the documented default is 30)

Working through the calculation

  • Applying the documented formula (Base mapping hours = data fields to map / mapping throughput rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 33.75 hr for total data mapping hours, the number this scenario is built around.
  • At this operating point the engine returns 25 hr for base mapping hours.
  • At this operating point the engine returns 35 % for complexity and validation hours added.
  • At this operating point the engine returns 6 pieces / min for mapping throughput (fields/hour).

How this compares with the baseline

  • Against the tool's baseline example, where complexity and validation allowance sits at 30% and the headline result is 32.5 hr, this scenario comes in 3.85% above the baseline at 33.75 hr.
  • It computes total analyst hours to map a set of data fields between two systems, padded for transformation complexity and validation. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Total data mapping hours: 33.75 hr (headline result)
  • Base mapping hours: 25 hr
  • Complexity and validation hours added: 35 %
  • Mapping throughput (fields/hour): 6 pieces / min
