What is PeopleAnalyst?

PeopleAnalyst is the front door for people-analytics research: 205+ works indexed and profiled, 40+ citation-grade findings extracted, and peer-reviewed behavioral science translated from academic to actionable — the missing manual for the people analytics you always meant to do.

What is people analytics?

People analytics is not a dashboard. It is behavioral science and statistical inference applied to workforce decisions — a discipline with its own methodology, spanning measurement, organizational design, talent, leadership, and analytics craft.

Why does AI in HR need measurement science?

AI is being deployed in high-stakes people decisions — hiring, performance, attrition — without the measurement science to evaluate whether it works or whom it harms. Construct validity, effect sizes, and criterion validity are the vocabulary for asking an AI vendor the right questions.

How is the research made accessible?

The evidence is indexed and searchable: 205+ works, 40+ citation-grade insight cards, and 8 research arcs, so the right finding reaches the right decision at the right time.

What separates good people measurement from assertion?

Good measurement has a method: construct validity, reliability, and effect-size interpretation are not optional — they are what separates evidence from assertion.

Lean Construction

In a sentence

This book collates 25 years of seminal research and practice in Lean Construction, presenting its core theories, themes, and practical approaches for improving productivity, quality, and value delivery in the construction industry.

Since Lauri Koskela first applied the 'new production philosophy' to construction in 1992, a global movement has been underway to transform one of the world's most vital yet inefficient industries. This comprehensive volume brings together the pioneers and leading researchers of Lean Construction to take stock of 25 years of progress. It introduces the reader to the foundational Transformation-Flow-Value (TFV) theory, which challenges traditional management paradigms by focusing on waste reduction and value generation. Through detailed explorations of core themes and practical approaches like the Last Planner System, Target Value Delivery, and Integrated Project Delivery, the book provides a robust framework for students, practitioners, and researchers. It serves as both an essential introduction to the state of the art and a forward-looking guide to the new frontiers of managing complexity, uncertainty, and collaboration in the built environment.

The model

This is a synthesized causal model from the book 'Lean Construction', which posits that the adoption of Lean principles and practices (Design Levers) improves key socio-technical project dynamics (Mediators), which in turn leads to superior project performance (Outcomes) by reducing waste and maximizing value. The model is grounded in the book's central argument that a shift in production theory from a simple 'Transformation' view to a holistic 'Transformation-Flow-Value' (TFV) view enables these improvements.

Lean Production Theory Adoption (TFV)design lever

The degree to which the project organization moves beyond the traditional 'transformation' view of production to a comprehensive 'Transformation-Flow-Value' (TFV) theory, which explicitly manages workflow and customer value creation.

Integrated Project Delivery Frameworkdesign lever

The use of relational contracts (e.g., IPD, Alliancing) and organizational structures that align commercial interests, share risks/rewards, and integrate key stakeholders early and throughout the project lifecycle.

Target Value Delivery Processdesign lever

The application of a disciplined management process that steers design and construction towards delivering a customer-defined value proposition within a constrained 'allowable cost'.

Last Planner System (LPS) Implementationdesign lever

The extent to which the project uses the Last Planner System for production control, including collaborative phase scheduling, lookahead planning, weekly work planning, commitment management, and systematic learning from variance.

Location-Based Managementdesign lever

The use of location-based scheduling and control techniques (e.g., LBMS, Takt Time Planning) to optimize workflow, ensure continuity of work for crews, and provide clear visualization of production flow.

Collaborative Design Managementdesign lever

The implementation of practices during the design phase that foster collaboration, explore alternatives, and improve decision-making, such as Set-Based Design, Choosing By Advantages, and early stakeholder involvement.

People and Knowledge Systemsdesign lever

The degree to which the project organization fosters a culture of respect, continuous improvement (kaizen), knowledge sharing, and leadership development at all levels.

BIM Integration with Leandesign lever

The synergistic application of Building Information Modeling (BIM) with Lean processes to enhance visualization, coordination, process transparency, and information flow for production planning and control.

Project Collaboration and Trustpsychological state

The quality of interaction and relationships among project stakeholders, characterized by teamwork, shared goals, open communication, mutual respect, and trust.

Workflow Reliabilitybehavioral pattern

The degree to which production assignments are completed as planned without delays or interruptions. It is a measure of the predictability of the production system.

Process Variability Reductionbehavioral pattern

The extent to which unplanned and disruptive variation in task durations, handoffs, and resource flows is minimized through better planning, standardization, and buffering.

Process Transparencypsychological state

The degree to which project status, production plans, constraints, performance metrics, and decision-making processes are visible and accessible to all relevant stakeholders.

Shared Understanding of Valuepsychological state

The extent to which all project stakeholders have a common and explicit understanding of the project's purpose, goals, and what constitutes value for the client and end-users.

Organizational Learning and Adaptationbehavioral pattern

The capacity of the project team to systematically learn from both failures (e.g., plan variance) and successes, and to adapt its processes and behaviors for continuous improvement.

Waste Reductionoutcome metric

The measured minimization of non-value-adding activities in all project phases, including overproduction, waiting, unnecessary transport, over-processing, excess inventory, unnecessary movement, defects, and making-do.

Project Predictabilityoutcome metric

The ability of the project to meet its baseline cost and schedule targets reliably and with minimal variance.

Customer Value Realizationoutcome metric

The degree to which the completed project fulfills the client's and end-users' purposes, requirements, and expectations, leading to satisfaction.

Project Productivityoutcome metric

The overall efficiency of the construction process, reflecting the ratio of outputs (e.g., value-adding work completed) to inputs (e.g., labor-hours, resources consumed).

Construction Quality and Safetyoutcome metric

The level of conformance to specifications, minimization of defects and rework, and the prevention of accidents and injuries throughout the project.
