Assignment on the Value stream mapping of the Company (Toyota)

Toyota motor corporation is a largest automobile manufacturing company in the world that started in 1933. There are more than 600 subsidiary companies that are involved in the production of commercial and industrial automobiles, and automobile parts. The headquarters of Toyota are in Toyota city in east of Nagoya Japan.  In the present work the value stream mapping is considered for Toyota.

Steps in Creating Value Stream Mapping of the Company (Toyota)

Value stream mapping can be described as a process items that flow through the value stream. for instance, in the manufacturing industry value stream mapping consider material items, design, and development of design items. In the service fields the mapping is used to fulfil the needs of the external customers. the value stream system centers on the added products and services that change the function and market of the services.  the steps of developing value stream mapping are listed below,

1.      Develop a team that create lean value stream map

2.      Develop Kaizen Kick off and Value stream map planning

3.      Identify the process family while planning

4.      Identify the similarities

5.      Create the current state map with VSM planning

6.      Start from the basic VSM template

7.      Create the future state map

8.      Create the VSM draft plan

Initial planning of the Company (Toyota)

Toyota organization usually begins with mapping starting and ending point. Through this the organization gets the idea regarding where the internal processes begins and how they reach to the end. By doing this the organization gets the idea of the whole processes which it performs for producing its vehicles. The map usually begins from material deliver from suppliers and ends where the corporation deliver its products to the customers.  As production processes of the organization are complex it maps each of the process is detail in the map.

Defining Steps of the Company (Toyota)

There are different steps which are performed by Toyota Corporation in order to produce the vehicle. From beginning to the end all the steps are going to be included in the map. In the second step of creating the value stream mapping the organization define the steps which are incurred in the production of vehicles. Some of the major steps are mentioned as follows:

·         material from supplier

·         assembling of the parts

·         finishing of the vehicle

·         test run

·         delivery of the vehicle’s in the showroom

All the steps are identified so that they can be included in the value stream map.

Indicating information flows of the Company (Toyota)

The value stream mapping provides detail information regarding the flow of information. From value stream map it can be known how information flows in the organization. In this step the management of the organization record the information regarding how information flows from one department to another department. In other words the organization indicates which person is responsible for delivering the information from one department to another. Managing the flow of information has huge significance for any organization because without effective information flow success of the organization is not possible.

Collection of Data of the Company (Toyota)

The fourth step of creating the value stream mapping in the organization is the collection of data. the data which the organization needs to collect in order to create value stream map are mentioned as follows:

·         transfer time

·         inventory items required in each process

·         number of workers required in each process

·         the products that are scrapped by the business

·         Batch size and pallet size etc.

All the detailed that is mentioned above is required by the management so that the value stream map can be created. The critical data is gathered by the team who create value stream map.

Adding Times Lines and data of the Company (Toyota)

In the 5^th step of the value stream map the team who is responsible for creating the map in Toyota Corporation begin adding the information in the map. The information which the team gathers in step 4 is now added in the map. Under each process data boxes are added. Under the data boxes the timeline of each process is included. This provides information about the actual time spent by the organization to produce the product and the lead time which is required for production of the goods. In this step all the important data is mentioned in the value stream map.

Identification of waste of the Company (Toyota)

The value stream mapping of Toyota increase feature and functionality without increasing the material usage and wasted time. Toyota production system use VSM for the waste production management and the process analyze material handling at each step. In the VSM of Toyota production system the process uses typical material information, mapping and process mapping for the management of the waste. The system use degree to which a process step can be switched quickly and inexpensively. The VSM is a key of success for Toyota production over the years. The ideal product information neve stops moving in the system (Asq. org, 2020).

Development of Value Stream Map of the Company (Toyota)

The VSM template was originally created by Toyota Motor Company and it was implemented properly through the process flowcharts and material. The model allowed Toyota to reduce the previous working process and activities. It allowed Toyota to remove all the nonessential activities and helped in maintaining the manufacturing process. The value stream mapping of Toyota adds functionality and features to the service and products that benefit the company and customers. figure 1 below provides the example of typical three-day VSM for the manufacturing process (Lucidchart. com, 2020). figure 2 below, illustrates the product family by introducing them in groups of services and members.

Conclusion of the Company (Toyota)

The value stream mapping in Toyota undergo through four steps starting with determination of process family, drawing the current state mapping, determination of future state map, and planning that arrive at the future state. The VSM model of Toyota examine the matrix with the similar and identical processing steps. For Toyota, it is important to find if there are some similarities in the functions then group them together with the same VSM team.
