When Smart Systems Fail: Why Family Businesses Must Combat Algorithmic Inertia
Family businesses increasingly rely on sophisticated algorithms for everything from inventory management to customer relationship systems. Yet new research reveals a critical blind spot: algorithmic inertia—when data-driven systems fail to adapt to environmental changes, leading organizations astray despite appearing to function normally.
Research by ABFI's Academic Director Vern Glaser and colleagues, published in MIT Sloan Management Review, examines how algorithmic inertia contributed to catastrophic failures at companies like Zillow and Moody's. For family businesses balancing technological advancement with traditional values, understanding these risks becomes essential for sustainable growth.
The Hidden Danger of Algorithmic Inertia
Algorithmic inertia occurs when organizations use sophisticated models to account for environmental changes but fail to keep pace with actual shifts in their operating environment. Unlike simple system failures, algorithmic inertia is insidious—systems continue producing results that appear reasonable while becoming increasingly disconnected from reality.
Zillow's spectacular failure illustrates this phenomenon. The company's Zestimate algorithm successfully estimated home values for years before market volatility in 2021 rendered its predictions obsolete. Despite having access to vast data streams, the system couldn't adapt quickly enough to new market dynamics. Zillow lost an average of $25,000 per home in the fourth quarter of 2021, resulting in an $881 million write-down.
For family businesses, this carries particular significance. Unlike large corporations that can absorb massive losses, family enterprises typically operate with tighter margins and less room for error. A single algorithmic failure could threaten generational wealth and employment for extended family networks.
Four Sources of Algorithmic Failure
Glaser's research identifies four critical factors that contribute to algorithmic inertia, each with specific implications for family businesses:
Buried Assumptions occur when organizations fail to revisit fundamental assumptions underlying their algorithmic models. Family businesses often face this challenge when transitioning from founder-led intuitive decision-making to data-driven processes. Initial assumptions about market conditions, customer behavior, or operational constraints may become embedded in systems without regular review.
Superficial Remodeling happens when organizations make only minor modifications to algorithms despite substantive environmental changes. Family businesses may be particularly susceptible to this due to resource constraints or reluctance to overhaul systems that previously delivered success.
Simulation of Unknown Future represents over-reliance on algorithmic predictions for future scenarios. Family businesses, with their long-term orientation and legacy concerns, may place excessive trust in models that simulate multi-generational planning horizons without accounting for fundamental shifts.
Specialized Compartmentalization emerges when technical experts developing algorithms remain disconnected from domain experts using them. In family businesses, this often manifests as generational divides between tech-savvy younger members and experienced older leaders who understand business nuances but lack technical depth.
Moody's Lessons for Family Business Governance
The research's detailed examination of Moody's credit rating failures during the 2008 financial crisis offers sobering lessons for family business governance. Despite developing sophisticated models explicitly designed to account for environmental changes, Moody's ended up downgrading 83% of AAA-rated mortgage-backed securities, contributing significantly to the global financial crisis.
Key governance failures included assumptions about mortgage quality that weren't updated as lending standards deteriorated, superficial model modifications that prioritized efficiency over accuracy, and organizational compartmentalization that prevented effective communication between quantitative analysts and rating committee members.
"We talked about everything but ... the elephant sitting on the table," admitted Moody's managing director of credit policy regarding declining mortgage underwriting standards that their high-level committee never addressed.
Family businesses can extract crucial governance insights from this failure. Board structures must ensure algorithmic oversight doesn't fall through cracks between technical and business expertise. Regular assumption audits become as important as financial audits for businesses increasingly dependent on algorithmic decision-making.
Practical Strategies for Family Businesses
Research suggests four practices that help organizations combat algorithmic inertia:
Expose Data and Assumptions: Document all data sources, fundamental assumptions, and decision parameters underlying algorithmic models. For family businesses, this means creating accessible explanations that bridge generational and technical knowledge gaps. Assumptions should be reviewed quarterly, not just when problems emerge.
Periodically Redesign Algorithmic Routines: Regularly overhaul models rather than making incremental adjustments. Family businesses should establish predetermined triggers for fundamental model review—such as significant market shifts, new competitive dynamics, or changes in family business strategy.
Assume Models Will Break: Actively consider scenarios outside algorithmic predictions. Family businesses' long-term perspective provides advantages here, as they can develop qualitative scenario planning that complements quantitative models. Legacy planning exercises can identify potential blind spots in current systems.
Build Bridges Between Technical and Domain Experts: Create formal structures ensuring data scientists and business experts collaborate effectively. Family businesses might establish "innovation marshal" roles—individuals with both technical and business expertise who can translate between different knowledge domains.
Implementation Considerations for Family Enterprises
Family businesses face unique challenges in implementing these practices. Resource constraints may limit ability to hire specialized bridge-building roles or conduct frequent model overhauls. However, family businesses also possess advantages: longer planning horizons, stable leadership, and deep institutional knowledge that can inform qualitative scenario planning.
Succession planning provides natural opportunities to address algorithmic inertia risks. As next-generation leaders bring technical expertise into family enterprises, they can establish practices that prevent dangerous disconnects between systems and business reality.
Board governance structures should explicitly address algorithmic oversight. Family business boards often focus on strategic guidance and family dynamics but may lack frameworks for evaluating technological risks. Regular algorithmic audits, conducted with same rigor as financial audits, become essential for businesses depending on data-driven decision-making.
Looking Forward: Technology and Family Business Strategy
As artificial intelligence and machine learning become more sophisticated, risks of algorithmic inertia will intensify. Family businesses must balance embracing technological advantages with maintaining healthy skepticism about algorithmic predictions.
The research emphasizes that algorithmic inertia isn't primarily a technical problem—it's an organizational and governance challenge. Successful family businesses will develop cultures that encourage questioning algorithmic outputs, maintaining human oversight of critical decisions, and regularly challenging fundamental assumptions embedded in their systems.
For family businesses, the stakes extend beyond immediate financial performance. Algorithmic failures can threaten generational wealth, family employment, and community relationships that family enterprises typically prioritize. Proactive governance of algorithmic systems becomes essential for preserving family business values while leveraging technological capabilities.
The lesson isn't to avoid algorithmic tools but to govern them effectively. Family businesses that establish robust practices for managing algorithmic inertia will gain sustainable competitive advantages while preserving the human judgment and relationship focus that defines successful family enterprises.
