Barriers to Effective Controls
• Size of organisation• Number of legacy systems• Corporate Governance– “Corporate Governance represents a model of self
delusion of the triumph of process over purpose” Paul Moore former Head of Group Regulatory Risk at HBOS
• Changing emphasis of audit

How CEC Uses IDEA
• Audit sampling– plus ability to extrapolate results
• Running data matches for clients• Summarising big data files for Corporate
Accounts• Importing print and pdf files• Exporting / file reformat to excel
![Page 4: Turning untidy data into a target rich environment](https://reader035.vdocuments.site/reader035/viewer/2022062721/568137a8550346895d9f51a7/html5/thumbnails/4.jpg)
Zeroing in on target
• Comparing databases without unique IDs• Initial search of population not sample• Asking searching questions of population– Identify potential high risk occurrences , or– Gain assurance that all seems well
• Conversion of print / pdf reports to enable random sampling or analysis
• Converting field types to allow comparison

Better understanding your data
• Low level bit by bit approach– Duplicate bank accounts • No bank account details• CEC tenants• Social Landlords• Major private landlords• Contrived tenancies• Staff who are landlords
![Page 6: Turning untidy data into a target rich environment](https://reader035.vdocuments.site/reader035/viewer/2022062721/568137a8550346895d9f51a7/html5/thumbnails/6.jpg)
Leveraging what we can
• Annual staff v benefits test for Revs & Bens• Ran whole Council– 2 significant peaks• Under £13,500 [ignored]• Over £30,000 [test checked Zero Hrs Supply staff]
– Sampled middle and hit jackpot• Visibility + deterrent

Controls Testing
• Continuous auditing rebranded• Effective [facts not opinion]• Can be set up in advance• Negates any down time / learning curve• Fulfils commitment to external auditor
![Page 8: Turning untidy data into a target rich environment](https://reader035.vdocuments.site/reader035/viewer/2022062721/568137a8550346895d9f51a7/html5/thumbnails/8.jpg)
Adding value to client
• Fuel key fobs 1,600 risk • 3 Databases– Fuel fob no employee no– Driver permit does– Roads / Fleet no access to Payroll
• Cleansed data, joined fuel and driver and matched against leavers
• Gave weight to other recommendations
![Page 9: Turning untidy data into a target rich environment](https://reader035.vdocuments.site/reader035/viewer/2022062721/568137a8550346895d9f51a7/html5/thumbnails/9.jpg)
Showing the client something they don’t already know
• Presentation to Revs & Bens SMT– all live claims over 105– highest 30– duplicate & missing NINOs– u25, no deps, no partner > single room rate
• Not telling us anything / “Thinking ...”• Under 60 over £16,500 savings - Jackpot

Staff & Procurement
• Aims– Compliance with Council’s Code of Conduct– Compliance with Procurement Laws / Procedures– Verify Value for Money– Target Potential Fraud
• Method– Match Payroll v Supplier Database
• Postcode + Leading Numbers from Address Exact Matches
• Inexact Matches
![Page 11: Turning untidy data into a target rich environment](https://reader035.vdocuments.site/reader035/viewer/2022062721/568137a8550346895d9f51a7/html5/thumbnails/11.jpg)
Issues IDEA overcame
• Edinburgh’s addressing system• Vendor address over 3+ fields • No unique identifier• Ability to exclude Carers • Split address into separate fields (excel)• Export just fields we needed
![Page 12: Turning untidy data into a target rich environment](https://reader035.vdocuments.site/reader035/viewer/2022062721/568137a8550346895d9f51a7/html5/thumbnails/12.jpg)
Results
• Employee transition to self employed £24,000 jumps to £230,000
• Husband with minibus got £690,000 over 3 years
• Staff invoicing us for same type of work• Partners of Education staff doing training in
H&S , Communications etc• Trades / catering / transport v high risk
![Page 13: Turning untidy data into a target rich environment](https://reader035.vdocuments.site/reader035/viewer/2022062721/568137a8550346895d9f51a7/html5/thumbnails/13.jpg)
Corporate Procurement
• Banging drum re EU compliance to no avail• Each department spend on suppliers > EU
thresholds– matched against corporate and departmental
contract database– asked Heads of Service to explain breaches
![Page 14: Turning untidy data into a target rich environment](https://reader035.vdocuments.site/reader035/viewer/2022062721/568137a8550346895d9f51a7/html5/thumbnails/14.jpg)
Multiple Contracts
• DSOs 18 hour contracts to avoid ER NI• Multiple posts to earn required wage• IDEA well placed to identity multiple
employee numbers on same NINO– Duplicate key exclusion• Field to match & field that should be different
• Also picked up people sharing a NINO
![Page 15: Turning untidy data into a target rich environment](https://reader035.vdocuments.site/reader035/viewer/2022062721/568137a8550346895d9f51a7/html5/thumbnails/15.jpg)
Inhibitions & Charges
• Council charge on property rather than force sale
• Data for audit on robustness of process print report with some cells only populated at start of page / section / change of type
• Imported using the populate empty cells function
• Enabled sorting by address / random sampling
![Page 16: Turning untidy data into a target rich environment](https://reader035.vdocuments.site/reader035/viewer/2022062721/568137a8550346895d9f51a7/html5/thumbnails/16.jpg)
Stratified Random Sampling
• As previous used populate empty cells to import NNDR reliefs & exemptions
• Stratified random sample to ensure coverage of all categories
• As a manager I will get exactly what I want tested
• Results evidenced, repeatable & can be extrapolated
![Page 17: Turning untidy data into a target rich environment](https://reader035.vdocuments.site/reader035/viewer/2022062721/568137a8550346895d9f51a7/html5/thumbnails/17.jpg)
New Risks
• DI Hatton from Police Scotland Counter Fraud Unit
• Identified in Police but could be any org– Youngsters being placed in Police as sleepers by
organised crime and accessing sensitive information after a fallow period
– Staff may have had a drug habit in youth but now clean. After 2-3 years feel confident to restart socially. Filmed by dealer and passed on to organised crime for blackmail
![Page 18: Turning untidy data into a target rich environment](https://reader035.vdocuments.site/reader035/viewer/2022062721/568137a8550346895d9f51a7/html5/thumbnails/18.jpg)
Pre IDEA tidy up (Excel)
• = find “ “ and @ left and @ mid – split addresses into separate cells
• @ upper @ lower @ proper– force change to character set for compatibility
• Conditional formatting for duplicates• Highlight anomalies and sort by colour
![Page 19: Turning untidy data into a target rich environment](https://reader035.vdocuments.site/reader035/viewer/2022062721/568137a8550346895d9f51a7/html5/thumbnails/19.jpg)
Controls don’t always do what intended
• Humane squirrel traps• Rivets at Forth Road Bridge• Cash check the day before payday• Signatures on form for adding supplier
![Page 20: Turning untidy data into a target rich environment](https://reader035.vdocuments.site/reader035/viewer/2022062721/568137a8550346895d9f51a7/html5/thumbnails/20.jpg)
In Summary
• Do a little bit at a time• Give clients evidence of control failure• Encourage staff to use IDEA or ask you to
process• Advertise benefits– Import / enhance / analyse / export to excel
• If you have a question about your organisations data IDEA can probably help answer it
