A Manager’s Guide to Harnessing Technology  11.3

  • Why would a firm use a loyalty card? What is the incentive for the firm? What is the incentive for consumers to opt in and use loyalty cards? What kinds of strategic assets can these systems create?
  • In what ways does Tesco gather data? Can other firms match this effort? What other assets does Tesco leverage that helps the firm remain among top performing retailers worldwide?
  • Make a list of the kind of data you might give up when using a cash register, a Web site, or a loyalty card, or when calling a firm’s customer support line. How might firms leverage this data to better serve you and improve their performance?
  • Are you concerned by any of the data-use possibilities that you outlined in prior questions, discussed in this chapter, or that you’ve otherwise read about or encountered? If you are concerned, why? If not, why not? What might firms, governments, and consumers do to better protect consumers?
  • What are some of the sources data aggregators tap to collect information?

A Manager’s Guide to Harnessing Technology  11.4

  • Discuss the possible consequences of a company having multiple plants, each with a different information system using different part numbers and naming conventions for identical products.
  • Why does it take longer, and require more processing power, to analyze sales trends by region and product, as opposed to posting a sales transaction?

A Manager’s Guide to Harnessing Technology  11.5

  • List the issues that need to be addressed in order to design, develop, deploy, and maintain data warehouses and data marts.
  • What is meant by “data relevance”?
  • What is meant by “data governance”?
  • What is the difference between a data mart and a data warehouse?
  • Why are data marts and data warehouses necessary? Why can’t an organization simply query its transactional database?

A Manager’s Guide to Harnessing Technology  11.5

  • Data relevance. What data is needed to compete on analytics and to meet our current and future goals?
  • Data sourcing. Can we even get the data we’ll need? Where can this data be obtained from? Is it available via our internal systems? Via third-party data aggregators? Via suppliers or sales partners? Do we need to set up new systems, surveys, and other collection efforts to acquire the data we need?
  • Data quantity. How much data is needed?
  • Data quality. Can our data be trusted as accurate? Is it clean, complete, and reasonably free of errors? How can the data be made more accurate and valuable for analysis? Will we need to ‘scrub,’ calculate, and consolidate data so that it can be used?
  • Data hosting. Where will the systems be housed? What are the hardware and networking requirements for the effort?
  • Data governance. What rules and processes are needed to manage data from its creation through its retirement? Are there operational issues (backup, disaster recovery)? Legal issues? Privacy issues? How should the firm handle security and access?
