Pull planning is a collaborative Lean construction method where project teams work backward from a specific milestone to define the sequence work and show dependencies between tasks. While the traditional paper-based process relies on physical sticky notes and Big Room meetings, digital transformation streamlines this by enabling real-time remote collaboration, automated data capture (like Percent Plan Complete), and seamless integration with master schedules. |

The Last Planner System® (LPS) was first developed in the ’90s by Glenn Ballard and Greg Howell. Many practitioners have implemented LPS using analog tools, as this enabled large groups to collaborate using walls, large templates, sticky notes and markers. This method and these tools facilitate group discussions, promise-making and coordination. And the Big Room environment is effective for many people to collaborate simultaneously.
The analog process used for LPS has proven to be very effective and well understood. However, paper-based LPS has limitations including:
Remote engagement - Everyone must be in the room to see the plan on a large wall. Engaging remote collaborators with photos of the analog wall, while possible, is not really effective.
Physical space - For large projects, there are often space limitations. Each team/plan would typically have its own planning board. These boards often need to me shuffled due to limited wall space.
Calculating performance - Percent Plan Complete (PPC) and reasons for variance must be tabulated manually as changes are made to the plan.
Information capture - Data from analog activity cards is not captured. Information from analog content must be transposed into digital form to be effectively utilized.
Legibility - Messy handwriting can be challenging for others to read.
Manual transcription - The tedious task of writing 10 identical cards for a single 10-day activity is not an effective use of time.
Information loss - Cards can fall off the wall, especially if the boards are moved around, which can affect the integrity of the plan.
Technology providers address these challenges in many ways. However, there is risk in transforming a process like the Last Planner System. Automation, taken too far, can result in unintended consequences that can compromise the effectiveness of the process. To highlight one example, when a task runs late, automatically moving dependent tasks can result in a lack of awareness and can limit discussion between trades to find an effective solution. This can negatively impact project performance. Automation can be valuable, but can result in losing essential conversations.
A variety of technologies, when brought together thoughtfully, can significantly enhance analog processes while capturing the critical elements that have made the process so effective.
Effectively transitioning to digital LPS requires understanding how people, process, technology and physical spaces are intertwined:
People – Central to the design of LPS is that the people who are closest to and responsible for the work being done can bring this knowledge together in a collaborative environment to optimize the project schedule.
Process – LPS is a process that is clearly defined and well understood. When implemented in an analog form, the system works as intended. When implemented in a digital form, it is essential that the integrity of the process remains intact.
Technology – There are many considerations for how technology should be applied. Pull planning is typically conducted in a large group environment, often with remote attendees. Technologies to support this process should include displays, process-oriented software, a conferencing application (e.g., Microsoft® Teams or Zoom) and room audio and video. Consideration should be given to how technologies fit with other tools. The ability to move data between applications can add significant value, save time and eliminate waste.
Spaces – Consideration for the space where collaboration takes place is important as well. Placement of technology solutions in the space, whether analog or digital, can enhance team performance by supporting and optimizing the process. This is even more critical when considering the requirements to support remote participants.

With significant benefits that new technology solutions can provide, it may be time to consider the advantages of a digital platform to implement LPS.
Here are some the advantages of switching to a digital approach for LPS:
Saving time - eliminate tedious time-wasting activities such as handwriting multiple cards and shuffling boards
Saving space - no longer need physical storage space for multiple analog planning boards, reducing site trailer costs
Quick adoption - teams are already familiar with the paper process, speeding up adoption
Better data capture - Capture data and conduct data analysis as a by-product of day-to-day activity
Remote access - Teams can collaborate in-room together, invite remote participants or access their plans from anywhere
As with many things, the trick is to keep all of the best elements of the analog process as you move to the digital realm.
Whether in a Big Room or working from home, Nialli™ Visual Planner takes LPS to a new level by leveraging what is already familiar and enhancing the process through innovative application of technology.
