3.1需求分析
会员制医疗预约服务管理信息系统的作用，可以提高会员制医疗预约服务管理的工作人员的效率，协助他们对会员制医疗预约服务信息进行统一管理，为管理者提供信息储存和查询搜索系统。一个良好的会员制医疗预约服务管理信息系统可以实现对会员制医疗预约服务的精细化管理：对在线会员制医疗预约服务管理流程的全过程进行电子化操作，其主要作用是管理和控制会员制医疗预约服务所有的信息，分析库存数据，使工作人员对会员制医疗预约服务管理信息系统进行监管，根据系统所提供的相应信息，采取适当的措施，及时补救管理中的漏洞，提高在线会员制医疗预约服务管理的工作效率，使得在线会员制医疗预约服务管理变的更加系统和规范。
3.2系统可行性分析
可行性分析是在进行初步调查之后，对系统开发的必要性和可行性的研究。针对本系统，主要从技术可行性，经济可行性，社会可行性，法律可行性等方面来论证，具体分析如下：
技术可行性：当今社会人类的科技水平的不断发展，软件开发产业也在不断的壮大。目前，市面上流行的开发产品，已经能过满足不同行业的各种需要。
经济可行性：在当今社会，计算机的性能已经有了很大的提升，价格也不断的下降。因此，并不需要对此程序投入过高的成本。并且，在程序投入使用之后，可以为管理人员带来极大的便捷，大大提高工作效率，减少人力浪费，避免许多不必要的工作和开支。
社会可行性：管理者效率的增加，以及在管理过程中出现错误的可能性的大大减少，也是为了更好的发展铺平道路服务大众。这理应得到各界的一致认可。
法律可行性：本系统绝不违反任何相关的法律法规。
3.3 系统现状分析
系统使用用户的数量直接决定了用户信息管理者的工作量，毫无疑问，管理者的工作量较大较繁琐。通过总结出系统当前对用户管理的工作状态得以下分析：
统筹规划，如果系统在信息化管理中不够全面，缺少综合性、系统性、整体性，那不可避免的需要投入大量人力物力来规划整理信息。引入信息化管理方式无疑可以达到节省信息管理成本的目的不仅减少资源浪费还可以使会员制医疗预约服务变得井井有条，成为市场竞争中的一大优势。
要循序渐进，做事不能心急，一步一个脚印，都不可能一步到位，就算信息管理系统也一样，要让系统发挥最大效率还是应该多调研，多听取用户和管理者的意见，并进行必要的统筹规划，有组织有目的地设计系统功能，团结各个部门发挥主观能动性。
(1)信息安全措施不到位
隐私权神圣不可侵犯，这是中华人民共和国宪法赋予我们的权利，人和人都不能侵犯我们的正当权益，而网络用户信息管理存在极大安全隐患，信息泄露的案列不在少数，加强信息安全措施是完善网络信息管理过程中不可避免的一环。
(2)资源不能充分共享
资源共享是网络的一大特点，没有共享就没有社交，网络也就失去了他应有的魅力，如果能够实现用户信息共享，无疑对于用户的发展存在不可或缺的帮助。
(3)现有系统可扩展性不高
如今科学技术发展飞速，随着而来的就是技术更新，那势必会给软件更新带来挑战，因此，系统必须具备良好的开放性和可扩充性，为了不落后于时代，这是必备特色之一。
基于上述分析，在线会员制医疗预约服务管理系统应该切合实际，做到确实有效，集体表现为：一是系统能够整理并集合归类用户信息，防止用户信息混乱，难以整理；二是系统要安全稳定，不能泄露用户信息，造成隐私泄露，不仅伤害用户利益更是对经营者名誉的损毁；三是系统要具有良好的开放性，不仅要方便定期的维护维修，更要方便及时增加新功能，保证先进的时代契合性。经过详细的讨论论证，确定系统的总体要求。
