The barriers to Supply chain management are:

(i) Lack of information technology: Without correct information technology, they cannot compete with other companies which are very efficient in framing their strategies and implementing new software to their companies to improve their efficiency and in other departments.

(ii) Unclear organisational objective: Even with all manpower, hard work and resources, if they don't have a common organisational goal among employees, it will not be possible to focus and work towards achieving that goal, which ends up in serious problems for the company.

(iii) Lack of education and training: Another main reason for the failure of SCM flow in a company, employees are not aware of the activities that are happening in the company and if they do not know what should be done, it results in total failure to the company.

(iv) Lack of financial resources: If all the planning and strategies are made, if one lacks financial resources, one cannot proceed further because implementing software and updation costs high and if not done, efficiency and other activities can cause loss to the company. 

(v) Lack of information sharing: Another important factor to be noted is information sharing, which flows from all the participants of SCM and helps in knowing the demands, customer needs, stock and inventory, which is the base for successful SCM.

(vi) Lack of Customer Satisfaction index: Customer satisfaction index is the main key to successful SCM and a poor index here shows the unstable position of the company, not maintaining the Key Performance Indicator -KPI, where taking necessary steps on the above points helps to improve customer satisfaction index and overall performance of the company.
