Osterling Consulting in La Mesa's Mt Helix area has delivered Lean Enterprise and Six Sigma transformations from its Woodland Drive headquarters since 2000. Construction and general-contracting firms like CREW builders, inc. represent a core engagement type, where value-stream mapping identifies cycle-time waste across estimating, procurement, and field-execution workflows. The principal holds a BS and MBA from San Diego State University and co-founded SDSU's Lean Enterprise Certificate Program in 1999, continuing as lead instructor with over 1,000 practitioners certified in Lean tools. Published methodologies include co-authored texts on kaizen event planning and metrics-based process mapping for office and service environments. Print-production operations like MAC Printing benefit from the same shop-floor-to-front-office approach, applying rapid-improvement events to reduce setup times and work-in-process inventory. The highest-impact engagements deploy full value-stream transformation across multi-site operations, integrating A3 problem-solving, standard-work documentation, and tiered visual-management boards to sustain $1 million-plus annual cost reductions.
