Last time I have written an article on comparing Scrum, Lean, Kanban, where I mentioned PULL and PUSH systems. In this article, I will describe the PUSH & PULL systems, their benefits, and I have also covered some of the critical aspects of the PULL system as that has been used across all Agile methodologies, frameworks, and processes. Apart from all this, I have also touched on some of the aspects of e-Kanban; I hope this article will make all of you understand the details of PUSH and PULL systems, their benefits, and a lot more of it.
What is Push and Pull System
Pull systems is the manufacturing system, where production is based on actual daily demands, and the information flows from the market to management. Like just in time system. It permits the person doing the work to pull in tasks when they are ready. It prevents people from feeling overloaded, and it forces people to prioritize.
Push systems are the manufacturing system, where production is based on the projected production plan, and the information here flows from management to market, like Maximum retail price. In the Push system, the work is given to a person, and the entire work is put into a massive to-do list. In this system, the person or the team commits to some amount of work in advance.
The pull system has limited inventory; it's customer-centric; it can improve the cash flow, and its make to order. Whereas the Push system has a high list, it's producer centric, it can make to stock, and the demands are based on forecasting.
For the Pull system, a good system balance must be in place; the setup time for the pull system will impact throughput, any problems with the pull system will lead to unhappy customers, and each of the jobs is a high-stress rush order job. In comparison, a push system can generate a large quantity of scrap before errors are discovered. It also requires the maintenance of large and complex databases and maintains adequate product flow; it requires much diligence.
As I have mentioned, the Push and Pull system with its advantages and disadvantages, so now let's understand the practicality of the same
Advantages and Disadvantages of Kanban Pull system in comparison with ERP/MRP Push System
In the current world, customers are demanding innovative and high-quality products at a lower price. It is only one part of the market demand. On top of this high delivery reliability, short delivery time, combined with substantial flexibility, is also in need. To meet such a requirement, all the organizations must organize themselves accordingly. In the evolving time, production and logistics areas play a critical role, and the decisive factor for the optimization of the system is the fast and flexible production system, which depends on the real customer demand. To fulfill this purpose, a PULL system plays a significant role and offers advantages over the traditional PUSH system.
Kanban is often used in the context of the PULL System/ process to control the overall flow of the materials/ production. A comprehensive Kanban system where external suppliers are connected can be prone to errors, and it is not very clear simultaneously. An Electronic Kanban system can be a better recommendation to support and optimize the process in such a condition. It is also known as e-Kanban.
Now imagine that simple visual methods and processes control the production process without the use of central planning and control of the complex ERP/ MRP system or other SCM systems. I know this is unthinkable, but many world-class companies have proven that consumption-based processes can be realized through Kanban. Unfortunately, a manual PULL system can reach its limits quickly, and it can be a clear disadvantage. The employees' effort for the software and technical support of the processes can be significantly reduced by facilitating daily management of the entire Kanban system. It makes the processes more transparent and safer. The visualization and targeted evaluation's versatility helped the processes and the whole systems noticeable and helped improve them continuously. So, e-Kanban is becoming essential for those companies who wanted to achieve the constant pull system.
Advantages of e-Kanban
There are many advantages that e-Kanban offers like great versatility, creating clear, transparent and flexible processes, and improving the systems continually. It can help transition complex forecast-based planning systems to a flexible and straightforward e-Kanban system with the integrated performance measurement. Usually, an e-Kanban driven pull system can be adjusted continuously, and it can be improved based on the Plan-Do-Check-Act cycle as the pulled system is being used everywhere in e-Kanban. So, net-net e-Kanban can become a robust universal tool for all the lean production activities for the future to ensure an organization's long-term competitiveness.
Some of the critical attributes of the PULL system
As I have mentioned, the Pull system allows "Just-in-time" delivery of work. There are other contrasting work processes, which helps the team member work on other different things simultaneously. A Pull system allows the team member to focus on one thing at a time. There are some key attributes of PULL systems, and those are namely:
- Ability to manage the change
- Ability to quickly adapt to new information
- Increased ability to scale up the team to a suitable size of the Project.
So, when something changes that impacts the business requirement, the team can quickly adapt by knowing that most of the work is already accomplished and can still be applied to the Project. Teams using the pull system become a self-managed team to a certain extent because the system can scale up the team or the ability for a team to accommodate different sized projects while remaining consistent.
The PUSH & PULL system becomes inevitable when it comes to Agile Framework, methodologies, and processes. More common in the Agile world is the PULL System, which provides the freedom to the entire Project team as the actual production is based on daily demands, and it helps the team not to feel overloaded. The more practical aspect of the PULL system can be seen in Kanban and scrum methodology.
