Achieving consistent, high-quality outcomes is one of the greatest challenges in data center projects. Quality lapses during planning, design, and construction phases are leading causes of cost overruns, project delays, and even critical outages—despite significant investments. Many organizations face gaps between design intent and real-world implementation, compounded by an overall lack of quality culture and clear metrics in the industry. Deficiencies in quality planning and assurance often result in compromised outcomes, diminished return on investment, increased lifecycle costs, and eroded customer confidence. To bridge these gaps, robust quality planning—anchored by a detailed Quality Assurance Plan for every system and subsystem across project stages—is essential for evidence-based decision-making and long-term data center reliability
