Construction companies that use the Last Planner® System have completed projects months in advance of scheduled completion date.
By planning in advance you avoid the typical all-out rush at the end of a project. By focusing on the overall goal of the project and not the speed of individual subcontractors, you can finish things faster.
This is best shown through real-life projects that finished ahead of schedule.
| Project | Scheduled Completion (Months) | Actual Completion |
| Seattle Children’s Hospital | 18 | 14 |
| Wisconsin Hospital | 38 | 36 |
| St. Louis Hospital | 26 | 24 |
| Toronto Tenant Finish | 14 | 8 |
| University Stadium East Stands | 10 | 8 |

Suffolk Construction has demonstrated savings in both time and money in two of their recent projects:
- Los Angeles Unified School District (LAUSD) South Region Middle School #3. The school was completed 2 months ahead of schedule AND saved approximately $1.05 million.
- Massachusetts College of Art and Design (Mass Art). After implementing Lean principles, Suffolk was able to cut 2 months off of the original project timeline.
