Example: organizational change analysis

“Because the company was structured around product lines rather than customer segments, it struggled to deliver integrated solutions. As a result, client satisfaction scores dropped by 15%. The leadership team therefore decided to implement a matrix structure, which subsequently led to improved cross-functional collaboration and consequently higher customer retention rates.”

Formal vs. informal cause-effect language

Formal (for reports, proposals)

  • “As a result of these factors”
  • “This has given rise to”

Less formal (for emails, presentations)

  • “That’s why”
  • “So”
  • “This means”

Common errors to avoid

  • Implying causation when only correlation exists
  • Using vague cause-effect relationships without evidence
  • Overusing the same cause-effect structures
  • Neglecting to consider multiple causes or alternative explanations
  • Confusing sequence with causation (“after this, therefore because of this”)
