How can companies with small CSR funds take up CSR activities in a project mode?

A well-designed CSR project can be managed with small CSR funds as well. 

Further, there is a provision in the Companies (CSR Policy) Rules, 2014 that enables such companies to collaborate with other companies for undertaking CSR activities by way of pooling their CSR resources. (Refer rule 4(4) in Companies (CSR Policy) Rules, 2014).
