Takt Time / Location-based Planning


 

Takt time planning - When the train falls off the tracks

Takt time planning is a great tool for aligning crews and creating flow on site. However, it’s still just a plan and it will inevitably fail at some point. One of the reasons for using takt time is not only to create flow, but also help pinpoint where the bottleneck is on site. In the long run that’s a good thing; don’t ignore your problems, they’ll just grow.

Aside from adding more crews, here are a few countermeasures to consider when executing a Takt time plan that’s gone off-beat.

The Last Planner ® System during the Finishing Phase in the World of Small Trade Partners

The Last Planner System (LPS) is a production planning and control system designed to produce predictable workflow and rapid learning in programming, design, construction and commissioning of projects. LPS has five main elements: (1) Master Scheduling, (2) Phase "Pull" Planning - what should get done, (3) Make Work Ready Planning - what can get done, (4) Weekly Work Planning - what will get done, and (5) Learning - what was done (did) [1]. The collaborative process of LPS promotes participation of those who do the work to plan the work.

A Deeper Look into LBMS Controlling System – Preventing Cascading Delays

In my previous post about LBMS, I mentioned that cascading delays can cause project duration increases of 10% or more. This blog article digs a bit deeper and explains what cascading delays are, why they happen in construction projects and how LBMS controlling can help to prevent them.

Introduction to Location Based Management System: CPM on Steroids Combined with Flowline Visualization

The Location-based Management System (LBMS) builds on decades of work on location-based scheduling methods. The first recorded utilization of location-based methods in vertical construction was in the Empire State Building. More systematic approaches followed. Line-of-Balance was based on optimizing production of identical locations.

5 Steps To Takt Time Planning

As a foreword to the post, I think there are many ways one can execute Takt time planning (TTP). The fact that there isn’t much research on the topic in construction means that it is definitely an open question. Through some iteration and research, the five step method below is the best practice to Takt time planning so far.

A Brief History of Location-based Scheduling and Takt Time Planning

Location-based scheduling methods are not new. In some countries such as Finland, the adoption of line of balance schedules is widespread and used for decades. However, in the United States these schedules have remained unpopular.

An Introduction to Takt Time Planning

‘Takt time’ is a term used in manufacturing to describe pacing work to match the customer’s demand rate. ‘Work structuring’ is the practice of scheduling out work and is a part of designing a production system. Takt time planning then, is one method for work structuring around a set pace of work. The goal of Takt time planning is to create a reliable plan, with the input of the entire team, which balances workflows for specific phases of work.
