How the record was built

  • The deals. Acquisitions of every size in the Stratrix Decision Cases whose outcome is known. Deals that never closed, deals too recent to call and buyouts by managers or investors (no buyer’s business to integrate into) are left out.
  • The outcomes. From the Decision Cases: each deal’s line below is quoted from its record, which links to the story it was drawn from.
  • The integration answers. From published reporting: company announcements and filings, press coverage, and academic and business-school case studies. Each answer quotes the page it came from, word for word, and links to it. Q&A sites, document uploads and essay sites are not used. Where the reporting does not say, the answer is left blank rather than guessed.
  • A caution on culture. Reporting that calls two cultures similar comes mostly from buyers’ announcements; reporting that describes a clash comes mostly from accounts written after a deal went wrong. Read that row as a record of what was said, and when, more than of what happened.
