近年来，随着物联网、云计算、移动互联等信息技术的快速发展，信息化在人们的日常生活中发挥着非常重要的作用，同时也改变了人们的生活方式。并且随着我国经济的快速发展，系统集成行业和信息化建设已经成为了国家发展战略，并且对国家整体经济的发展有着战略性的意义。因此，越来越多的系统集成商也像雨后春笋般涌现出来，使得行业的竞争越来越大，同时也就导致了利润逐渐下滑。

本文以Y系统集成公司 (Y公司) 作为主要研究对象。Y公司成立于1988年，也是伴随着系统集成行业成长的一家老牌公司，公司是为交通、政府、教育等行业提供集成项目设计、系统应用解决方案直至全方位项目实施的高科技类公司。近年来，Y公司由于业务营销方面的问题导致公司利润下滑的现象。本文应用了PEST分析、波特五力模型和SWOT分析、STP理论、关系营销理论等相关营销理论工具，通过对Y公司所处的外部环境和内部环境的深入分析，了解到Y公司在业务营销中存在的相关问题，如大客户营销策略的缺乏、销售模式过于单一、服务意识淡薄、业务团队缺乏培训。结合目标市场选择和市场定位以及关系营销和营销组合等相关理论，提出Y公司针对上述问题的业务营销调整方案。Y公司应加大对目前优势行业的深挖，对重点客户的关系营销做到位，并同时结合营销组合策略开展全面的业务营销工作，而且要对其它有潜力行业加大投入，同时对公司的营销结构和树立公司品牌意识及建立完善的激励制度、加强团队建设等方面出进一步调整。从而有效的保证企业新的营销策略的实施落地，希望通过这一系列措施能改善Y公司现有状况，从而扩大公司市场占有率，也希望有利于其它同类型公司学习和借鉴，最终对完善系统集成行业市场的业务营销管理有所帮助。
