Process Mapping Techniques for CPHQ Candidates

Process mapping is a fundamental skill for healthcare quality professionals. The CPHQ exam tests your knowledge of different mapping techniques and when to use each one.

Basic Flowcharts

A basic flowchart uses standard symbols (rectangles for process steps, diamonds for decisions, ovals for start/end, arrows for flow direction) to show the sequential steps in a process. Top-down flowcharts list major steps with sub-steps beneath each one, providing a hierarchical view. Deployment (cross-functional or swim lane) flowcharts add horizontal lanes for each role or department, showing who performs each step and where handoffs occur. Deployment flowcharts are particularly valuable in healthcare because they reveal handoff points where errors and delays commonly occur.

Detailed Process Maps

Detailed process maps capture every step, decision point, loop, and branch in a process. They are most useful for analyzing complex processes where problems may be hiding in the details. When creating a detailed map, always document how the process actually works (the "as-is" state), not how it is supposed to work (the "should-be" state). The gap between the documented procedure and actual practice often reveals improvement opportunities.

Value Stream Maps

Value stream maps go beyond traditional flowcharts by adding data about each step: cycle time, wait time, defect rate, and whether the step is value-added or non-value-added. This Lean tool helps teams identify waste and opportunities for streamlining. Value stream maps are most appropriate for complex, end-to-end processes that span multiple departments.

Spaghetti Diagrams

Spaghetti diagrams map the physical movement of people, materials, or information through a workspace. Lines are drawn on a floor plan showing actual paths traveled. This technique is effective for identifying unnecessary movement (a Lean waste) and optimizing physical layouts. In healthcare, spaghetti diagrams have been used to redesign nursing stations, pharmacy layouts, and surgical suites to reduce walking distances and improve efficiency.

Choosing the Right Map

For the CPHQ exam, match the mapping technique to the situation. Use basic flowcharts for simple processes, deployment flowcharts when handoffs are a concern, detailed maps when investigating complex problems, value stream maps for end-to-end process analysis, and spaghetti diagrams for physical layout optimization.
