ODM Business Overview

ODM Business

Based on past experience of leadership team in product design services for global customers and products design / manufacturing services for Indian market, we decided to launch Rhombus, ODM Division of Masibus which can provide complete product engineering outsourcing services global customers. This will combine benefit of talent pool available in India for design and Masibus' manufacturing experience in past 4 decades.

India is known traditionally for software services and product design services. There are EMS vendors in Asian countries which take care of production and supplies. This model is good for consumer products. For industrial products, customers need single point responsibility for entire product. This calls for ODM Model where customer can focus on core competency of market research, fundamental research, marketing and sales. Rest of the engineering functions can be completely outsourced without investment or deploying resources.

Examples of ODM Business Model

Industrial Products

With advancements in technologies, it is difficult for product companies to have people with experience in all new technologies. Sometimes, due to lack of availability of skilled manpower, companies are not able to add products to their portfolio. They can define the product and hand it over to an ODM for engineering and manufacturing and focus on their core competence products. By using an OEM, they still don’t have control of the product. In case of ODM model, they can still own the Intellectual property of product and have greater amount of control and flexibility over the product.

Defense Products

The Defense segment has vastly been associated with technological advancements. More than strategies, the ease and use of technology create a bigger impact. The need for specific and accurate products and the lack of resources can both be handed over to the ODM engineering and designing.

Medical Products

Medical companies work on fundamental research on new procedures or diagnosis. They can focus on their core competency by outsourcing electronics design and manufacturing for the products to an ODM.
