Strategy Tools: Pareto (80/20) analysis

Strategy Tools: Pareto (80/20) analysis

Pareto (80/20) analysis - illustrative example

Pareto Analysis is a statistical technique for decision making that is used for selecting a number of tasks that produce significant overall effect.1 It is based on the Pareto Principle (the 80/20 rule) which states that by doing 20% of the work you can generate 80% of the benefit of doing the whole job. The Pareto Analysis is named after Vilfredo Pareto, an Italian economist who lived in the late 19th and early 20th centuries. In 1897, he presented a formula that showed that income was distributed unevenly, with about 80% of the wealth in the hands of about 20% of the people.2

The figures 80 and 20 are illustrative; the Pareto Principle illustrates the lack of symmetry that often appears between work put in and results achieved. For example, 13% of work could generate 87% of returns. Or 70% of problems could be resolved by dealing with 30% of the causes. The sum of the two numbers does not need to add up to 100 all the time.

The following conclusions are illustrative of potential Pareto outcomes2:

  • 80% of customer complaints arise from 20% of your products or services.
  • 80% of delays in schedule arise from 20% of the possible causes of the delays.
  • 20% of your products or services account for 80% of your profit.
  • 20% of your sales-force produces 80% of your company revenues.
  • 20% of a system’s defects cause 80% of its problems.

Fast Facts

While African insurance premiums have been growing they have not kept up with GDP growth

While African insurance premiums have been growing they have not kept up with GDP growth

The African insurance industry is predominantly group life insurance business, and due to limited spending power there has been much slower uptake of individual insurance policies.
Poverty has been reduced somewhat in Africa but this is primarily in the lowest income bracket of the middle class who are prone to falling back into poverty.
Furthermore, policyholders are typically unaware or sceptical of the benefits of owning insurance products, they are difficult to reach and often do not earn regular incomes.1
Microinsurance products are growing more quickly – this presents an opportunity for targetting lower income groups.

Quote: Stephen Schwartzman – Blackstone Founder

Quote: Stephen Schwartzman – Blackstone Founder

“I always felt that somebody was only capable of one super effort to create something that can really be consequential. There are so many impediments to being successful. If you’re on the field, you’re there to win, and to win requires an enormous amount of practice – pushing yourself really to the breaking point.” – Stephen Schwarzman – Blackstone Founder

Stephen A. Schwarzman is a defining figure in global finance and alternative investments. He is Chairman, CEO, and Co-Founder of Blackstone, the world’s largest alternative investment firm, overseeing over $1.2 trillion in assets.

Backstory and Context of the Quote

Stephen Schwarzman’s perspective on effort, practice, and success is rooted in over four decades building Blackstone from a two-person start-up to an institution that has shaped capital markets worldwide. The referenced quote captures his philosophy: that achieving anything truly consequential demands a singular, maximal effort—a philosophy he practised as Blackstone’s founder and architect.

Schwarzman began his career in mergers and acquisitions at Lehman Brothers in the 1970s, where he met Peter G. Peterson. Their complementary backgrounds—a combination of strategic vision and operational drive—empowered them to establish Blackstone in 1985, initially with just $400,000 in seed capital and a big ambition to build a differentiated investment firm. The mid-1980s financial environment, marked by booming M&A activity, provided fertile ground for innovation in buyouts and private markets.

From the outset, Schwarzman instilled a culture of rigorous preparation and discipline. A landmark early setback—the unsuccessful investment in Edgecomb Steel—became a pivotal learning event. It led Schwarzman to institutionalise robust investment committees, open and adversarial (yet respectful) debate, and a relentless process of due diligence. This learning loop, focused on not losing money and fact-based challenge culture, shaped Blackstone’s internal systems and risk culture for decades to come.

His attitude to practice, perseverance, and operating at the limit is not merely rhetorical—it is Blackstone’s operational model: selecting complex assets, professionalising management, and adding value through operational transformation before timing exits for maximum advantage. The company’s strict approval layers, multi-stage risk screening, and exacting standards demonstrate Schwarzman’s belief that only by pushing to the limits of endurance—and addressing every potential weakness—can lasting value be created.

In his own words, Schwarzman attributes success not to innate brilliance but to grit, repetition, and the ability to learn from failure. This is underscored by his leadership style, which evolved towards being gentle, clear, and principled, setting high standards while building an enduring culture based on integrity, decency, and open debate.

About Stephen A. Schwarzman

  • Born in 1947 in Philadelphia, Schwarzman studied at Yale University (where he was a member of Skull and Bones) and earned an MBA from Harvard Business School.
  • Blackstone, which he co-founded in 1985, began as an M&A boutique and now operates across private equity, real estate, credit, hedge funds, infrastructure, and life sciences, making it a recognised leader in global investment management.
  • Under Schwarzman’s leadership, Blackstone institutionalised patient, active ownership—acquiring, improving, and timing the exit from portfolio companies for optimal results while actively shaping industry standards in governance and risk management.
  • He is also known for his philanthropy, having signed The Giving Pledge and contributed significantly to education, arts, and culture.
  • His autobiography, What It Takes: Lessons in the Pursuit of Excellence, distils the philosophy underpinning his business and personal success.
  • Schwarzman’s role as a public intellectual and advisor has seen him listed among the “World’s Most Powerful People” and “Time 100 Most Influential People”.

Leading Theorists and Intellectual Currents Related to the Quote

The themes embodied in Schwarzman’s philosophy—singular effort, practice to breaking point, coping with setbacks, and building institutional culture—draw on and intersect with several influential theorists and schools of thought in management and the psychology of high achievement:

  • Anders Ericsson (Deliberate Practice): Ericsson’s research underscores that deliberate practice—extended, focused effort with ongoing feedback—is critical to acquiring expert performance in any field. Schwarzman’s stress on “enormous amount of practice” parallels Ericsson’s findings that natural talent is far less important than methodical, sustained effort.
  • Angela Duckworth (Grit): Duckworth’s work on “grit” emphasises passion and perseverance for long-term goals as key predictors of success. Her research supports Schwarzman’s belief that breaking through obstacles—and continuing after setbacks—is fundamental for consequential achievement.
  • Carol Dweck (Growth Mindset): Dweck demonstrated that embracing a “growth mindset”—seeing failures as opportunities to learn rather than as endpoints—fosters resilience and continuous improvement. Schwarzman’s approach to institutionalising learning from failure at Blackstone reflects this theoretical foundation.
  • Peter Drucker (Management by Objectives and Institutional Culture): Drucker highlighted the importance of clear organisational goals, continuous learning, and leadership by values for building enduring institutions. Schwarzman’s insistence on codifying culture, open debate, and aligning every decision with the brand reflects Drucker’s emphasis on the importance of system and culture in organisational performance.
  • Jim Collins (Built to Last, Good to Great): Collins’ research into successful companies found a common thread of fanatical discipline, a culture of humility and rigorous debate, all driven by a sense of purpose. These elements are present throughout Blackstone’s governance model and leadership ethos as steered by Schwarzman.
  • Michael Porter (Competitive Strategy): Porter’s concept of sustained competitive advantage through unique positioning and strategic differentiation is echoed in Blackstone’s approach—actively improving operations rather than simply relying on market exposure, and committing to ‘winning’ through operational and structural edge.

Summary

Schwarzman’s quote is not only a personal reflection but also a distillation of enduring principles in high achievement and institutional leadership. It is the lived experience of building Blackstone—a case study in dedication, resilience, and the institutionalisation of excellence. His story, and the theoretical underpinnings echoed in his approach, provide a template for excellence and consequence in any field marked by complexity, competition, and the need for sustained, high-conviction effort.
