**1.4 Lean tools and techniques**

Several industries introduce Lean by seeing Lean as a series of 'tool'. For a while, this could be helpful, but in the long run, it will not be enough. Behavior is developed by defining values like as dragging the Andon chord when a difficulty arises, but it continuously does this, always expects it, and always supports it [39]. Lean techniques are the base of lean thinking and the most common applied techniques are listed below:

#### 1. 5S

It is the most common methods used in lean management. Starting the Lean journey with 5S, however, might not be a good idea. Although 5S is simple to incorporate, it has improve the efficiency and quality, it can also be a distraction from real goals or simply clean-up [39]. A 5S program's real goals should be:

It is necessary for senior management to be supportive before introducing the 5S Lean technique.

Since 5S may be ideal model for many organizations, even if they understand the concept of it. Using the model methodology is one way of helping workers grasp 5S. It targets small section of the shop floor and implements 5S there. Before any consideration is given to moving to another location, the 5S should be identify every detail. The primary reason for doing this is to inspire employees to look and assess the outcomes of 5S with their previous way of working. Since 5S would be the better option compare to the older ways, the workers would be ready and able to proceed to other regions and eventually the whole business with it.

i.**Sort:** Everything sorted in the work area. First, they categorized what is required for manufacturing and what are not required. Those that are not needed in the work area or serve no purpose must be discarded immediately. The company can choose to red tag products when in doubt. Red tag is a sticker indicate the date of object and then it is discarded if the object is not used up to the date [17].

The products are sorted accordance with the use. High use equipment's are kept close (perhaps daily) as possible to staff so that they do not waste time reaching them. Those that are used less often are positioned slightly further (perhaps once a week) so it is easily reachable to the workers, but not very near as to compete with the use of regularly used objects. Lastly, those that are seldom used are kept furthest away (per-haps once a month).

The sorting should be carried out regularly, maybe single time in a month but it is habit [18, 40].
