A business novel co-authored with aisling-ching, Ching's daughter, published in 2024 as part of the "Theory of Constraints Simplified" series. The collaboration marks a new dimension in Ching's writing — both a family project and an experiment in genre, blending detective fiction with business pedagogy.
The story follows teenage detective Billy Brown, who is brought in to save a failing cinema from bankruptcy. Each case Billy investigates is drawn from real businesses, grounding the fictional narrative in actual diagnostic problems. The detective frame is well-suited to TOC pedagogy: finding a bottleneck is structurally similar to solving a mystery — gathering clues, testing hypotheses, identifying the root cause hiding behind symptoms.
The focccus-formula provides the investigative framework. Billy's methodology for locating "productivity killers and profit thieves" maps directly to the Find, Optimize, Coordinate, Collaborate, Curate, Start-again steps that Ching introduced in the-bottleneck-rules. The detective narrative makes this process concrete and memorable in ways that a direct explanation cannot — consistent with the business-novel-as-pedagogy tradition Ching has worked in throughout his career.
The book extends bottleneck-thinking into a format that could reach readers who would not pick up a business guide — younger readers, fiction readers, or business owners who want stories rather than frameworks. It connects to rolling-rocks-downhill in approach but differs in audience: where Rolling Rocks targets software leaders, The Bottleneck Detective aims for general business readers.
The co-authorship with aisling-ching brings a new voice to the series and suggests an intergenerational transmission of the ideas — fitting for a book that is itself partly about inheritance, both of failing businesses and of the tools to save them.
