背景调研
志愿者服务小程序可以使志愿服务更加有序和高效,方便志愿者参与,也方便组织方管理和组织志愿服务活动;志愿者可以方便的在手机上报名,查看记录,获取积分,了解积分排行; 同时提供积分商城模块,可以让志愿者使用通过参与活动所获得的积分来兑换各种奖励或福利.
功能规划
【用户端】
- 活动浏览: 志愿者可以浏览各种志愿服务活动,了解项目的具体内容、时间和地点等信息。
- 在线报名: 提供在线报名功能,志愿者可以方便地选择感兴趣的活动并提交报名申请。
- 个人信息管理: 志愿者可以管理个人信息,包括联系方式、技能和经验等。
- 志愿服务活动记录: 记录志愿者的活动历史,包括参与的活动、服务获取积分等。
- 积分获取和排行榜:每次活动可以获得一定数量的积分,后台也可以手工给与特别贡献者额外积分奖励。并按积分进行排行张榜公布。
- 积分商城: 提供各种商品或服务供志愿者兑换,可以包括礼品、优惠券、志愿者服务证书、特殊活动的参与资格等。
【管理端】
- 活动发布:发布新的志愿服务项目,包括项目介绍、时间、地点和所需人数,完成活动获取积分数等信息。
- 报名管理: 管理方便地查看志愿者的报名情况,确保志愿者的匹配和合格。并可以导出每次报名的Excel名单。
- 积分商城管理:可以录入可供兑换的商品信息,并设置所需积分数。
- 积分兑换订单:可以检索和查看用户兑换记录,并设定是否领取的状态;也可以取消某订单。
- 用户管理:查看和检索用户资料,积分明细,并手工给与特别贡献者额外积分奖励;也可以导出用户资料为Excel。
- 统计分析: 可以按月统计本月注册人数,活动发起数,报名人数,签到人数等 。
