To remove unnecessary items from the workplace that no longer add value. Now these can be anything i.e. old phone books, obsolete tools, excess paperwork, etc. Ask questions from yourself that “Do we really need this?”. And if you have any doubt about then immediately sort it out.

Red Tagging

What is Red Tagging?

Red Tagging is putting red tags on items that need to be evaluated as to whether they are needed or not.

Note: Red Tagging is not for alone worker but this is for the team effort required.

7 Steps to Red Tagging

1. Identify Target Area: Identify the target area for red tagging.

2. Define Criteria for Red Tagging: After identification of red tagging items that item should be put under observation for some time (so that it can be using or not) and if the item is not used then that item may be disposed of or moved to another location / apart store. There are 3 key factors for decide that items should kept for use or that should go for red tagging.

- usefulness of item.
- the frequency of item needed.
- quality of item needed.

3. Design and make Red Tags: Each company / industry should design their own red as per their requirement, culture and feasibility which includes quality of paper, color of tags, contents typed on tag and must be approved from a higher and competent authority.

4. Conduct the Red Tag Session: (Red Tag Log Sheet)

5. Evaluating Red Tagged Items: Evaluation of red tagged items as per the requirement (i.e. sell it, shred it, donate it, etc.) to be done by a team under supervision.

6. Dispose of Unnecessary Items:

7. Move remaining red tagged items into holding area means red tagged item to move to apart store after entering them in Red Tag Log Sheet. It should also mention that which items will keep for how long in the store, when to sell that item, etc.

To give such item to any garage sell or such shops or company. In todays world there are also sites which purchase trash online (i.e. ebay, craigslist, etc.) as per their guidelines and policy. these items can be useful for other purpose eg: electronics can be used for teaching, waste papers may recycle, defective tools may melt and remake tools again.

Seiton

Definition

To arrange all necessary items in such a way as to maximize the production or output or workers. It works on the principle “A place for everything and everything in its place.”

Why Straighten is required in an organization?

After implemented straighten rule, items it is easy to find & return and also it is easy to know that its lost or issued to someone. This also reduce worker’s frustration (causing mental ill-health, stress and others) when tracing something in store during their working hours.

You can take an example of Reliance Fresh store where fruits and vegetables are placed in its column or row. Office desk or drawers when arranged properly, medical instruments at hospitals and many more if you observe in your surroundings.

Straighten rule also have following outcomes:

- Safety essence.
- Ergonomics.
- Quality.
- Productivity.
- Standard work.
- Morale and a lots…

3 Steps of Straighten

Understand the current situation:
- What tools and supplies are needed?
- How people perform the work?
Decide where thing belong: There are lots of items (useable or non-usable) at your workplace, some are issued and some are under your charge but after your working hours those items or tools must go to their place from where they have issued or taken, they may be your tools, electronics, stationaries, garbage, benches, machines, supplies, etc.
Decide how things should be stored: If the items are easy to locate it doesn’t mean they also easy to retrieve. Well it means proper stacking or item sequencing at store. i.e. shadow boards,

These can be done by ‘3 F’ Standards. Those are:

- Fixed Location
- Fixed Item
- Fixed Quantity

Fixing above-mentioned so that items may easily get when needed and they should be kept in secure location after working.
