1、职工档案管理系统可行性研究报告1引言职工档案管理系统是一个信息管理软件，意图在于方便查询职工档案的信息，并提供职工信息情况，可应用于各大、中、小型企业。使用本软件，不仅可以提高企业查询职工效率，还可以取代人工劳动，降低劳务开支。1.1编写目的本报告的编写目的在于研究职工档案管理系统是否可行，指出开发本软件所使用的方法和手段，并对软件的前景进行分析。预期读者 职工，管理员。1.2背景a. 工程的名称：职工档案管理系统。b. 产品用户：企业，中间用户。c. 产品的生产者：xxx组d. 产品的设计者：xxx组。e. 产品的所有者：xxx组。1.3符号、缩略语和定义职工档案管理系统，即本文档所讨论之软

4、理流程和数据流程职工跑路员综合数据库（一般为纸媒介）信息员管理员3.2工作负荷现有的职工档案管理系统所进行的工作有：1. 信息收集与记录：收集各个职工的档案情况，可以对其进行添加。2. 信息查询：通过该系统可以查询到职工档案的基本情况（所在部门，所在岗位，姓名等）3. 对信息的添加。如来了一个新的职工可以他的档案信息添加到该系统里面去。并具栓出功能。4. 对个人的简历，通过该系统可以看的见职工的简历。5. 对系统所查询到的结果可以进行单个打印，也可进行全部打印3.3费用开支需要开支的项目：人员工资、使用一部到两部电话所产生的费用、使用一个固定的办公地点所产生的费用、对新上岗人员进行培训所产生的
5、费用。由于本项目的试验性质以及小组目前的能力，不对以上列出项目的具体开支进行分析。3.4人员为了现有系统的运行和维护，需要以下人员：1到2名信息管理员，负责接听领导所示情况和职工打电话来查询档案的情况。1到2名接线员。3.5设备现有系统需要使用1到2门电话，需要提供传统的信息记录手段。3.6局限性本系统的主要的局限性有：响应慢，处理功能不足，处理能力很低。以上局限性的产生都是基于以往系统是建立在人工处理的基础之上。因此对现有系统的改进性维护已经不太乐观。4所建议的系统以下将说明所建议系统的目标和要求将如何被满足。4.1对所建议系统的说明本系统是一个完全自动化的档案查询系统，通过该系统的应用，管
6、理员可以方便的查询到职工的档案情况，把人从繁重而重复性的劳动中解脱出来，为企业提高工作效率，节省资金，是企业人工到数字化的转变的必要项目之一。4.2处理流程和数据流程职工档案信息个人简历情况得到数据结果逻辑关系逻辑关系档案记录打印个人简历档案浏览修改内容打印信息查询条件查询结果添加、删除查询条件查询结果查询条件查询结果修改内容修改内容4.3改进之处A. 计算机的响应速度和传统的手工响应速度不在一个数量级上；B. 由于1和2，所建议之系统运行的效率必然超过原有的系统。4.4影响本部分将说明在建立所建议之系统时，逾期将带来的影响：4.4.1对设备的影响本系统不可在原先系统的基础上构建。企业要建立一
7、个新系统，需要配备至少一台处理速度足够快且可以连接Internet的计算机作为服务器，并且根据人员数量配置几台可以连通该服务器的计算机。4.4.2对软件的影响无4.4.3对用户单位机构的影响为使本系统能够有效运行，采用本系统的企业必须对可能接触到本系统的人员进行培训，使其熟悉系统模块的使用方法，基本了解数据库的结构。需要1到2名管理员。4.4.4对系统运行过程的影响A. 新系统将完全改变用户的操作规程，由手工操作转变为自动化操作；B. 不再由手工处理任何数据；C. 数据将通过网络直接进入系统数据库；D. 数据将保存在数字化存储设备上；E. 系统一旦失效，带来的负面影响比较大 4.4.5对开发的
8、影响A. 除非企业有特殊要求，否则各种数据库的资料将预设空值或无意义值，不需由企业提供任何数据资料。B. 为了开发和测验本系统，需要2-8台可以联网的一般PC。C. 除非企业对职工有什么特殊的管理需进行查询和调查，否则不涉及保密与安全问题。4.4.6对地点和设施的影响无影响。4.4.7对经费开支的影响由于本项目的实验性质，不需要人员工资。但打印文档、使用计算机资源都将产生费用。粗略估计应在10000元左右。4.5风险分析和局限性 风险分析：由于是小组进行实验模拟，不存在风险分析。技术性风险：目前开发小组对需求的认识尚未统一，最终的系统可能无法完全满足用户的需求。本小组成员的能力尚未确认，他们不
9、一定拥有合适的技能，最终可能使项目的技术性能降低，也可能产生少量延迟。由于联系的问题，客户不会全程参与需求定义工作。这可能使生成的产品退化。为规避以上风险，采取了以下措施：1、 小组将要求组员在进行任何开发前在小组会议上讨论其对需求的理解。小组不能在任何成员对需求有异议的情况下进入开发。2、 小组将指定专人对组员进行培训，并要求组员平时进行自学。3、 一旦风险变成现实，小组将启动危机处理过程，将损失减至最小。商业性风险：由于本系统的实验性质，不会投入到真正的商业环境中，因此不存在商业风险。局限性：由于本项目组存在的周期较短，对最终生成的系统的维护将会比较困难。4.6技术条件方面的可行性A. 对
10、于运行平台的约束，由于现有的大量基于Win32的技术及它们的易用性，不会对项目产生重大影响；基于Delphi7、BDC，本系统所涉及数据库的实现不存在任何障碍；由于时间限制机组员的技术水平，本系统所涉及之网络功能的实现可能存在障碍，最后可能会留到下一周期开发。B. 开发人员的数量可以满足要求；开发人员的实际技术水平还不明确，不一定保证完全满足要求，可能会造成拖延。C. 本小组已有完善的进度安排和明确的人员分工，完全可能按时交付。5投资及效益分析 5.1支出由于本项目的实验性质和组员的现有能力，在此不列出支出的来源，不进行定量分析。5.1.1基本建设投资企业购置计算机的费用。5.1.2其他一次性
11、支出对员工的培训费用。5.1.3非一次性支出不存在5.2收益分析由于本项目的实验性质和组员的现有能力，在此仅列出收益的来源，不进行定量分析。5.2.1一次性收益A. 系统投入运行后，需要的人员数量大大减少，减少的人员工资；B. 由计算机更科学的分配时间，使同样时间内管理员能处理职工档案管理增加，由此引起的收益；C. 由于对信息的管理和分析更快捷，将有效提升企业在查询职工档案管理方面的效率。5.2.2不可定量的收益信息处理的自动化将引起由于人工误操作而导致的风险的减少；6 结论综上所述，本项目启动的条件已经满足，可以立即实施，但开发过程中需要注意前文中提到的风险。附录：项目开发初步规划人员分工：
