买方供应商交换是基于双方之间的固有关系。“关系”一词涵盖了供应链管理中的许多含义。它们源于战略关系、战术关系和内部关系。维持平衡需要供应链的概念。如果一个利益相关者拥有过多的权力和影响力，就会破坏供应链的有效性。维持供应链的一个基本原则就是个人才能和贡献的力量。这是由Michael Porter(Mangan and Lalwani,2016年)开发的价值链概念的微妙协议。价值链中有五个主要步骤。这些是入站物流、操作程序、出站物流、营销、销售和服务。在这方面，关系的作用或双方的权力在运作过程中起着重要的作用。人们已经注意到，建立供应链和价值链的概念更符合参与过程的利益相关者的需求。当然，这取决于不同利益相关者之间的关系。该分析的目的是了解买方供应商的权力对买方供应商的交易管理和结果的重要性。以下是关于价值链流程的简要概述。
Buyer supplier exchange is based on the innate relationship between the two parties who are involved. The term “relationships” covers a lot of meaning in the supply chain management. They stem from strategic relationship, tactical relationship and internal relationships. The notions of supply chain are needed for maintaining the balance. In case of one stakeholder wielding too much power and influence, there can be the undermining of the effectiveness of the supply chain. One of the fundamental principles of maintaining the supply chain is the power of the individual talents and contributions into the mix. This is the nuanced protocol where the idea of value chain was developed by Michael Porter (Mangan and Lalwani, 2016). There are five main steps in the value chain. These are inbound logistics, operational procedures, outbound logistics, marketing, sales and services. In this, the role of the relationship or the power of each party plays an important role in the operational process. It has been observed that the notions of creating of the supply chain and the value chain are more attuned towards the needs of the stakeholders who are involved in the process. Invariably, this depends on the relationship between different stakeholders. The purpose of this analysis is to understand the buyer-supplier power to be important to the management and outcome of buyer-supplier exchanges. A brief overview about the value chain process has been detailed in the following.
