A recent iiA Survey indicated the global recession is having an impact on internal audit activities.
Survey respondents felt that “better risk management could have played a role in preventing the current crisis...internal auditing could have done more to assist their companies in identifying key risks.”

When considering the economic crisis and the role you play as an auditor, what can you do to make a difference?
in the iiA report, richard Chambers suggests that audit can help to reduce inefficiencies through CAAts and data analytics. to be successful, audit will need to take the following steps:
Get buy-in from management �
Acquire and reconcile data �
Make it repeatable �
Read on for step-by-step guidelines on how to establish a sustainable data analytics program!

TIP: Focus on those areas with highest ROI first, they may recover dollars in areas that are a pain point for management
Getting Started!
Obtain Buy-In from Management. Start small and produce high value. Depending on your risk assessment, a great place to start might be with an Accounts Payable analysis. One duplicate payment could pay for the tools needed to implement a cost-recovery program within your organization.
Other reviews you can perform for quick and impactful results are
PCard �
Accounts Payable �
travel & Entertainment Expenses �
Acquiring and Reconciling Data. reconciling your data to make sure it’s complete is key. For example, we like to think there are no fraudulent people in our organization but if the person we’re requesting the data from is the one committing fraud, they might be smart enough to give us everything except the fraudulent data/journal entries. Make sure all the data is there.
Making it Repeatable. Some may not see the long-term value in technology investments. However, the time and efficiency savings you will achieve by making tasks repeatable will save your organization money and will allow your department to keep up with your workload even with limited human resources.

Develop Plan
this first step is crucial to identify audits that would benefit from data analysis. Ask yourself these questions:
is this an area of high risk that would benefit from more intensive oversight? �
in prior years, have steps been taken to confirm that complete data populations have been obtained? �
is there a need to focus on particular types of transactions / situations within the larger population? �
Are the audit procedures designed to look for exceptions? �
identify Audit Approach and Schedule
What procedures are required to support the audit objectives? »
Define the specific data analysis tests accordingly »
Define Coverage Desired
Consideration of period cutoff »
Consideration of specific sub-populations (e.g., business units) and / or other specific exclusions »
Define Data and Documentation requirements
What data is required to support the audit objectives? »
Who are the key it contacts associated with the required data? »

Summary
treat your data analytics implementation as a program because software alone will not get you to where you want to go. A successful program must involve people, processes and technology.
Engage your organization’s people in your program objectives, explaining to them what you are seeking to �achieve and what benefits to the organization will result.
Develop your plan with an understanding that you will need to have recurring access data and have a good �working knowledge of the business processes you want to scrutinize.
recognize that you will need to change not only your audit engagement process, but also how you interact �with the rest of the organization during the course of audits and in subsequent follow-up.
Data analytics technology will help you improve audit efficiency and the overall quality of audit results only if �your staff knows how to use it. training and ongoing development are key elements to a sustainable and effective program.
the benefits are significant - both in terms of the improved confidence in your audit results and the quality of insight you provide. With a sustainable data analytics implementation, you’ll improve your overall audit efficiency and consistency of work performed. these are outcomes definitely worth pursuing.
