Without a doubt, one of the most fundamental and important steps a product team can take is detailing out clear requirements for the manufacturing process. Having a comprehensive requirements specification sheet allows your CM partner to move forward and do what they do best - get products built on time and on budget. So while there are benefits of creating quality requirements, there are consequences of creating poor ones. Whether in manufacturing, engineering, product development, or software development, these consequences can be grave, appearing in all downstream activities, including architecture, design, implementation, and testing.
Whether on a political, economic, or environmental level, the notion of manufacturers altering their processes to be more sustainable - yet still emphasizing quality manufacturing - is always in the news. Frequent studies come out analyzing the current state of sustainable manufacturing and recommendations are made, and many contract manufacturers learn to adapt, both in order to properly align with regulations and to encourage sustainability throughout the manufacturing process. 
The RFP evaluation process is designed to clarify many aspects of potential partnerships and deliverables – the quality of the vendor, the scope of the project, and the outcomes on which success will be measured.
When writing perfect requirements for your product, there is a lot of ground to cover. After you have clearly specified your requirements, you still need to take the all important step of verifying them. 
“Time is money.” That phrase may not be more true than in the fields of product development, engineering, and manufacturing. Lapses and delays don’t just cause a minor inconvenience here - rather, every day you fall behind schedule can mean lost revenue.
One of the biggest challenges a product development company encounters is a lack of in-house resources required to solve a problem. This can range from the obvious (product manufacturing) to the more specific needs (software error handling), but when a company doesn't have the needed staff, time, or resources to move forward, they need to find and select a strong technology partner.
