Review the market size analysis & output
Demand Study
Study Methodology
Module I
Market Size Analysis
In-depth exploration of market size and segmentation objectives and deliverables analysis
In-depth interviews conducted to assess and create a market size and segmentation model
This effort will also assist in the development of the Module II survey tool (identifying/ validating key questions)
Module II
Quantitative Survey
Martec will execute an online survey leveraging The IIA’s member and non-member contact list
Min of 1200 interviews from IIA database, supplemented with 300 respondents (outside panel) who claim to be internal auditors
Estimated length = ~15 to 20 minutes, ~1200 interviews
Specific sample plan/screening criteria TBD upon input from the IIA team
Output from this survey will drive key objectives and deliverables including support of the Module I market size, segmentation analysis as well as identifying key motivations, barriers, and behaviors for IIA audience
Module III
External Stakeholder
In-depth interviewing effort with key C-suite/ Board level executives in support of the external stakeholder objectives and deliverables
~40 interviews will be conducted in this Module
Note: Incentives required to generate appropriate participation among this group of key decision makers
Interviews will also allow Martec to validate and pressure test portions of findings developed in the Module I and II exercises
Market Size Analysis
four approaches
Market Size Analysis Methodology
1. Internal Data Points
The first step in building the market size model yielded some broad starting point numbers:
Martec interviewed key IIA leadership members for feedback and impressions on the market size
Estimates ranged from 160,000 to 500,000+ internal auditors in the US and Canada
Martec collected valuable insights into the following key topics:
Key segments/ industries
Government vs. private sector insights
Service provider industry role
In-source vs. outsource
Member penetration rates/ IIA growth insights
Titles/ roles
2. Secondary Research & Data Support
The second step of our approach supported the market size model with:
Supporting research to identify auditor counts, trends, etc.
Headcounts/ Employee totals by industry sector
Starting point data for auditor ratio analysis
Source: BLS data in the US and Labour and employment data in Canada (canadabusiness.ca)
Identifying titles (over 50+ variants)/ LinkedIn analysis
Identifying/ and recruiting experts for primary research and model pressure testing
3. Primary Research
Primary interviews with internal audit professionals in target industries allowed us to benchmark headcounts and ratios.
Martec has completed ~35 interviews in support of the model development focusing on the following areas:
Validate audit department sizes
Create/ validate assumptions on audit to employee ratios
Develop/ validate industry segment variables
Develop insights around government/ public sector market size
Develop insights in support of services sector market size(e.g. Protiviti, PwC, etc.)
4. Fine Tune & Validate
Module I: Conduct additional primary research in support of ongoing model
Module II: (Quant Survey) to evaluate/ refine targeted data points
Company type, size and industry sector
Others, TBD
Module III: Stakeholder interviews to validate macro level findings, ratios, etc.
Based on our current analysis and modeling, we estimate the NAR internal audit population at ~230,000.
Market Size
The market is comprised of the following key segments:
Private Industry: ~130,000 (bottoms-up analysis)
Public sector/ Government: ~55,000 (primary research and separate model)
External Service Providers: ~45,000 (top down and bottom—up)
