American Bank requests an international telecoms solution Understand Your Profitability Drivers 1 Telco initiates multiple processes Understand Your Profitability Drivers 1 An example of a Telecoms process System System System System You need to understand the profitability of your core process ● ● ● ● ● Cost of installing 3rd party equipment Cost of leasing international lines Cost of hiring contractors or local workers Cost of lead generation and sales Revenues generated from service Understand Your Profitability Drivers 1 Performance is also useful... ● ● ● ● How long does it take to service a line? Which team receives the most orders? Which engineers perform the most revisits? What is the Process Cycle Efficiency? Understand Your Profitability Drivers 1 “Huh?

Demonstration... Build a Financial Performance Model 2 But isn’t this just business intelligence? Precisely. It’s where modern data quality technology is heading. Data Quality metrics and business performance metrics are measured the same way but for years they’ve been separated. You need to bring them into the same environment if you want to engage and focus the business.

Each system can have great quality data when measured against isolated data quality metrics but... … if you measured data quality and financial impact across a broader process it could still result in significant lost revenue and profits Key Tip: Assessing the quality of each system in isolation it won’t give you the full story Create an holistic data quality system 3 For example: Completeness Completeness in the [Planning.Inventory] column tells us if there are any missing values but... Value Complete? Juniper M320 YES Juniper M320 YES Juniper M312 YES Juniper m320 YES JUNIPER (M320) YES Create an holistic data quality system 2 3 For example: Completeness ... it doesn’t tell us if there are other values that should be there from [Stocks.Inventory] Master Stock Item Qty Juniper M320 10 Juniper M312 7 Juniper M315 3 Juniper M325 2 Juniper M327 15 Lack of coverage Value Complete? Juniper M320 YES Juniper M320 YES Juniper M312 YES Juniper m320 YES JUNIPER (M320) YES Create an holistic data quality system 2 3 For example: Completeness ... it doesn’t tell us if there are other values that should be there from [Stocks.Inventory] Procurement Catalogue Cost Juniper M320 40000 Juniper M312 90000 Juniper M315 890 Juniper M325 500 Juniper M327 100 Lack of price context Value Complete? Juniper M320 YES Juniper M320 YES Juniper M312 YES Juniper m320 YES JUNIPER (M320) YES Create an holistic data quality system 2 3 Step 3: Create an Interrogative Reporting Layer Create an Interrogative Reporting Layer 4 Reporting Layer By this point you will have a consolidated view of your: ● Financial Metrics ● Data Quality Metrics ● Performance Metrics Create an interrogative reporting layer 4 What does the overall architecture look like? Dashboards and Visualisation DQ Assessment Rules Data Profiling/ Discovery Data Repository and Storage Information Chain Management DQ Monitoring and Alerts Data Integration/ Movement Create an interrogative reporting layer 4 This gives you much greater clarity of the impact of poor quality data ● How long does it take to complete an order? ● What staff costs are involved in fulfillment? ● What costs are incurred when data quality errors force a re-design? ● What is the frequency of delayed orders over the last 12 months? Create an interrogative reporting layer 4 Adding performance and financial data creates focus One telecoms company found their fulfillment processes were taking longer and were increasing their stock of unplanned equipment Create an interrogative reporting layer 4 The issue lay with a rogue software release that introduced defects into the information chain Software Change Added Defects enter the information chain Holistic Reporting System monitors data quality, financial and performance metrics Alarm Raised Create an interrogative reporting layer 4 Summary Takeaway #1: Stop thinking of data quality assessments in terms of isolated analysis Summary Takeaway #2: Understand how your business model operates and create an end-to-end view of it, identifying data sources along the way Summary Takeaway #3: Focus on the goal of your data quality assessment and create an architecture to support that objective e.g. Data Quality impact on Service Levels Summary Takeaway #4: To create engagement and focus from the business make sure that you’re integrating business metrics into your reporting and underlying assessment architecture. Summary Takeaway #5: Don’t spoon-feed the business with canned reports, give them an environment that they can interrogate, let them discover the issues that matter to them most (hint: it will change over time too) Questions?
