Toyota is widely recognized as the leader in LPD. Its practices have been described by a number of oft-cited articles and books [Kennedy, 2003; Liker, 2004; Liker et al., 1996; Sobek, 1997a, 1997b; Sobek et al., 1998, 1999; Ward et al., 1995a, 1995b], and the comprehensive book by Morgan and Liker [2006], and are not repeated here, although some enablers listed in Chapter 7 have been inspired by these.

They described PD project integration, strategy, planning, management complexity, integration of problem-solving cycles, and the Toyota and Honda project management styles, which they describe as “heavyweight.”
