Types of waste in ABC Motors

ABC Motors has problems like unnecessary movement, too much inventory, and delays. These show the following wastes:

• Transport – moving parts too much

• Inventory – having too many materials stored

• Motion – workers moving more than necessary

• Waiting – workers or machines waiting before work continues

Lean tools to reduce waste

Lean tools help reduce waste and make work faster and easier:

• 5S – keeps the workplace clean and organised

• Kanban – controls how much inventory is kept

• Just-In-Time (JIT) – materials arrive only when needed

• Better layout and planning – reduces delays and movement

How does removing waste help save cost and improve efficiency?

Removing waste saves money, reduces time, and helps workers do their jobs faster. It also improves productivity and product quality.

What challenges might ABC Motors face when using Lean?

The company may face resistance from workers, need training and experience temporary disruption when changing processes.

Can Lean be used outside manufacturing?

Yes. Lean can be used in hospitals, schools, offices, and service businesses to reduce delays and improve efficiency.

suggestion: Reorganise the floor so parts move the shortest distance possible

Inventory

Desc: high inventory levels taking up space

Suggestion Kanban: only order or produce parts when the next station needs them

Motion:

Desc: unnecessary physical movement by workers

Suggestion 5S: workstations so every tool has a designated, ergonomic spot.

Waiting

Desc: frequent delays in production because of idle

Suggest: implement error-proofing to prevent stops

• Reduces non‑value‑adding activities

• Cuts storage costs and floor space

• Shortens lead time 

• Improves workflow and labor productivity

Inventory: overstock tires; reduce stock for tires

Motion: worker walking long distances to retrieve tools; relocate the tool storage place

Waiting: Assembly line halted due to delayed component; redesign the workflow such that it’s lean

• Don’t have enough man power to optimize the process or increase productivity

• Location obstacles, need transportation to deliver materials

• Lack of technology to optimize the process

1. Motion - Unnecessary movements due to poor workstation layout. waste of time

2. Inventory - High inventory levels of raw materials. Ties up capital and also requires storage space.

3. Waiting - Frequent delays in production which reduces productivity

4.Transportation - Parts or sub-assemblies are being moved unnecessarily which causes extra transportation fees and time.

Leans tools:

Motion and waiting - 5s

Inventory and waiting - Kanban system

Inventory and transportation - JIT

Waiting and Motion - Line balancing and Takt time

Discussion prompt

1. Removing waste saves money,time and increase the productivity by decreasing the waste

2. Need training, experience and also followed the rules

3. Yes it can be used beyond manufacturing

Description in ABC Motors

Suggested Lean Solution

Transport

• Unnecessary motion that’s unspecified and Frequent Delays in production.

• Rearrange the product/material position for easy transportation using Cellular Manufacturing or Kanban

Inventory

• High Inventory levels

• Manage Inventories and material flow, JIT (Just-in-Time) recommended. Pull into and out of inventory only on demand basis, in small quantities.

Motion

• Unnecessary motion that’s unspecified and Frequent Delays in production.

• Organise Workplace (Could implement 5S) and remove unnecessary movements.

Waiting

• Frequent Delays in production.

• Line Balance for workload balancing between phases/stations.

Transport- Unnecessary movement of car parts between distant workstations.

Inventory- High inventory levels of components piled up along the assembly line, causing clutter and tying up capital.

Motion- Workers walking long distances for bending, or searching for components due to poor workstation organization.

Waiting- Production delays where workers are idle waiting for parts.

Suggested Lean solution

Transport- Redesign the layout and minimize the travel distance.

Inventory- Reduce excess stock

Motion- Organize the workspace so tools and parts are immediately at hand, eliminating unnecessary movement.

Waiting- Just-in-Time & Balanced Workload

Description in ABC Motors - Car parts and sub-assemblies are moving long distances between workstations and storage areas, adding no value and increasing handling time. 

Suggested Lean Solution - Layout redesign & cellular manufacturing to place processes closer together; use Kanban to reduce unnecessary material movement. 

Inventory -  

Description in ABC Motors - Excess raw materials and work-in-process (WIP) are stored on the shop floor, tying up capital and hiding production problems. 

Suggested Lean Solution - Just-In-Time (JIT) production and Kanban systems to control inventory levels and produce only what is needed. 

Motion -  

Description in ABC Motors - Operators frequently walk, bend, or reach excessively to retrieve tools and parts due to poor workstation organization. 

Suggested Lean Solution - 5S (Sort, Set in Order, Shine, Standardize, Sustain) and ergonomic workstation design to minimize unnecessary movement. 

Waiting -  

Description in ABC Motors - Workers and machines experience downtime while waiting for parts, instructions, or previous processes to be completed. 

Suggested Lean Solution - Line balancing, standardized work, and pull systems (Kanban) to synchronize processes and reduce delays. 

Skills- underuse of specially skilled workers for local labor processes

Waiting- idle time for waiting for materials and preceding processes

Motion- unnecessary movement of team mates to different departments for different purposes.

2 Required lean

a. For inventory, purchase parts in bulk and store in storage for future use to save cost when price rockets

b. Highly skilled workers should be moved to automation rather than the menial Labour jobs

c. Waiting_ idle time is reduced when materials are on ground and personnel’s for previous and next job schedule are available and efficient

D. Motion- reducing unnecessary movement as each departments should have their own tools and supervisors

*Eliminating these will help the company deliver on time and help reduce waste of time and harness talents for better roles. This is cost effective.

*The challenges for the company in introducing the lean approach will be mainly how workers adapt to the new culture of working and also align their goals to been proactive for efficiency.

*Lean can be applied beyond manufacturing, it can be applied in construction ( timelines and activities), railways ( processes and pick up time), logistics etc

Lean solution; kaban - To reduce movement

Transport : Inefficient and excessive movement of raw materials between distant manufacturing and storage areas.

Lean solution; kaban - To reduce movement

Inventory: excess raw materials not being processed

Lean solution; JIT : raw materials should be ordered only when needed to avoid accumulating them in excess.

Waiting : downtime in waiting for raw materials

Lean solution; kaban - To reduce idleness
