Introduc:on to PCF
• Founded in 1982 • Based in Hemel Hempstead • Specialists in graphical repor:ng for projects • Customers include:

The Challenge of Project Repor:ng
• Your organisa:on/customer has a standard set of reports in a predefined format
• Your project management tools cannot produce them – Data comes from mul:ple sources – Need to create specific charts/graphics
• There is acute :me pressure to deliver
![Page 5: C5 PCE 2012 Presentation - Project Controls Expo PCE... · QEIProductArchitecture(Published Data JPEG, BMP, QEI Environment Database Model Data tasks breakdown structures resources](https://reader030.fdocuments.us/reader030/viewer/2022020316/5b5a17da7f8b9aa30c8b5a26/html5/thumbnails/5.jpg)
What Usually Happens Next
![Page 6: C5 PCE 2012 Presentation - Project Controls Expo PCE... · QEIProductArchitecture(Published Data JPEG, BMP, QEI Environment Database Model Data tasks breakdown structures resources](https://reader030.fdocuments.us/reader030/viewer/2022020316/5b5a17da7f8b9aa30c8b5a26/html5/thumbnails/6.jpg)
Why Choose a Spreadsheet?
• Familiarity – available on every desktop • Easy to import/paste in data • Built in char:ng and graphics func:ons • Bypasses the IT department
![Page 7: C5 PCE 2012 Presentation - Project Controls Expo PCE... · QEIProductArchitecture(Published Data JPEG, BMP, QEI Environment Database Model Data tasks breakdown structures resources](https://reader030.fdocuments.us/reader030/viewer/2022020316/5b5a17da7f8b9aa30c8b5a26/html5/thumbnails/7.jpg)
Is This Wise?
• With Excel on every desktop, on the surface it would seem like anyone can build a spreadsheet. And yet just because someone knows how to use Word, we don’t automa:cally assume they are a good writer.
• The task of developing the spreadsheet o]en goes to the person with the most relevant domain knowledge, rather than coding exper:se
![Page 8: C5 PCE 2012 Presentation - Project Controls Expo PCE... · QEIProductArchitecture(Published Data JPEG, BMP, QEI Environment Database Model Data tasks breakdown structures resources](https://reader030.fdocuments.us/reader030/viewer/2022020316/5b5a17da7f8b9aa30c8b5a26/html5/thumbnails/8.jpg)
Error Rates • Large body of research now exists • Over 80% of all spreadsheets contain errors • Typical cell error rate (CER) is roughly 1% • Inspec:on of spreadsheets by experienced users picks up roughly 50% of errors
• The structure of spreadsheets makes it easy to create errors, and hard to iden1fy them

Error Cascades
Wrong Result: CER = 0.87% Poor Prac:ce: CER = 1.79%

Error Checking is Hard...

Spreadsheet Risks • Easy to mix data and logic -‐ makes debugging difficult • O]en created by staff with no formal programming training • Model may never have been validated with test case data • Logic within model (or how to use the model itself) may not
be documented • No control on integrity of data once extracted from source(s) • Spreadsheet is o]en "owned" by an individual, rather than
the organisa:on
![Page 12: C5 PCE 2012 Presentation - Project Controls Expo PCE... · QEIProductArchitecture(Published Data JPEG, BMP, QEI Environment Database Model Data tasks breakdown structures resources](https://reader030.fdocuments.us/reader030/viewer/2022020316/5b5a17da7f8b9aa30c8b5a26/html5/thumbnails/12.jpg)
Other Issues
• Data is dead – just numbers, with no associated structure
• Transferring/formalng data at each period end can take a long :me
• Need to decide repor:ng :me unit in advance for :me scaled data (eg weeks, months)
![Page 13: C5 PCE 2012 Presentation - Project Controls Expo PCE... · QEIProductArchitecture(Published Data JPEG, BMP, QEI Environment Database Model Data tasks breakdown structures resources](https://reader030.fdocuments.us/reader030/viewer/2022020316/5b5a17da7f8b9aa30c8b5a26/html5/thumbnails/13.jpg)
Things to Consider • Was a requirements document ever issued? • Where did the model come from (e.g. wriden for this project,
copied from another project, downloaded from the web?) • Has the model ever been formally tested? • Is there any documenta:on? • What risk assessment has been performed – what would be
the consequence of – Delivering incorrect results? – The “owner” moving elsewhere?

How Does It Work?
• Data is imported via a wizard to create a snapshot model of the live project
• Mul:ple projects can be imported into a single QEI database
• Reports are built as graphical views linked to the data model
• Allows data from mul:ple sources to be combined into single set of reports
![Page 17: C5 PCE 2012 Presentation - Project Controls Expo PCE... · QEIProductArchitecture(Published Data JPEG, BMP, QEI Environment Database Model Data tasks breakdown structures resources](https://reader030.fdocuments.us/reader030/viewer/2022020316/5b5a17da7f8b9aa30c8b5a26/html5/thumbnails/17.jpg)
What Data Is Stored?
• WBS, Tasks and Logic • Calendars • Resources • Cost Rates • Baseline Data
It is also possible to create alternate breakdown structures for repor:ng purposes
![Page 18: C5 PCE 2012 Presentation - Project Controls Expo PCE... · QEIProductArchitecture(Published Data JPEG, BMP, QEI Environment Database Model Data tasks breakdown structures resources](https://reader030.fdocuments.us/reader030/viewer/2022020316/5b5a17da7f8b9aa30c8b5a26/html5/thumbnails/18.jpg)
Resources
• Values can be displayed as quan::es or costs • Values can be calculated for any single resource, a group of resources, or all resources
• Curves can be computed for any point in any breakdown structure
• Costs can be calculated from mul:ple :me varying sets of rate data
• Time varying availability values can be displayed
![Page 19: C5 PCE 2012 Presentation - Project Controls Expo PCE... · QEIProductArchitecture(Published Data JPEG, BMP, QEI Environment Database Model Data tasks breakdown structures resources](https://reader030.fdocuments.us/reader030/viewer/2022020316/5b5a17da7f8b9aa30c8b5a26/html5/thumbnails/19.jpg)
Key Benefits
• Process can be automated via macros • PMO retains control of repor:ng • Data model allows for “what if” modelling:
– Schedule slippage – Varying resource availabili:es – Varying resource rates
• Allows integra:on of data from mul:ple sources into a single en:ty

Case Studies
![Page 25: C5 PCE 2012 Presentation - Project Controls Expo PCE... · QEIProductArchitecture(Published Data JPEG, BMP, QEI Environment Database Model Data tasks breakdown structures resources](https://reader030.fdocuments.us/reader030/viewer/2022020316/5b5a17da7f8b9aa30c8b5a26/html5/thumbnails/25.jpg)
Example 1 (Defence Contractor)
• 35,000 tasks spread over 600 projects and 200 departments
• Monthly 250 page report pack took PMO 3 days to prepare
• Use of QEI reduced report produc:on :me by 80% and introduced EV graphics for all projects
![Page 26: C5 PCE 2012 Presentation - Project Controls Expo PCE... · QEIProductArchitecture(Published Data JPEG, BMP, QEI Environment Database Model Data tasks breakdown structures resources](https://reader030.fdocuments.us/reader030/viewer/2022020316/5b5a17da7f8b9aa30c8b5a26/html5/thumbnails/26.jpg)
Example 2 (Aircra] Manufacturer)
• Used QEI to visualise aircra] build configura:on, generate per-‐shi] ac:vity charts and assess impact of new orders on capacity
• Customer quotes: – "for the first &me we are able to fully visualise what our staff are achieving on a shiB by shiB basis"
– "once we had built the QEI model we could adjust the sequence of opera&ons, significantly improving our assembly &mes -‐ in some cases by up to 60%"
![Page 27: C5 PCE 2012 Presentation - Project Controls Expo PCE... · QEIProductArchitecture(Published Data JPEG, BMP, QEI Environment Database Model Data tasks breakdown structures resources](https://reader030.fdocuments.us/reader030/viewer/2022020316/5b5a17da7f8b9aa30c8b5a26/html5/thumbnails/27.jpg)
Example 3 (Water Company JV)
• 140 projects, £250m total budget • Budgets, progess and actuals were all originally in separate Excel spreadsheets used to record subcontractor data
• Unable to determine programme performance or generate :mely reports
• Now produce EV and performance reports in QEI direct from single spreadsheet – full period end import takes approximately 15 minutes
![Page 28: C5 PCE 2012 Presentation - Project Controls Expo PCE... · QEIProductArchitecture(Published Data JPEG, BMP, QEI Environment Database Model Data tasks breakdown structures resources](https://reader030.fdocuments.us/reader030/viewer/2022020316/5b5a17da7f8b9aa30c8b5a26/html5/thumbnails/28.jpg)
Example 4 (Interna:onal Airline)
• Significant percentage of fleet approaching 10 year overhaul, each aircra] out of service for a month plus labour costs of £1m+
• Exis:ng inhouse systems unable to predict when checks would fall due
• QEI was used to predict dates/costs of work based on flying paderns and various maintenance scenarios, to iden:fy most cost-‐effec:ve solu:on
