Information systems(IS)are critical for Performance Management(PM).Information systems greatly aid in defining,measuring and monitoring performance metrics and comparing them against targets and benchmarks.It is a topic you need to be ready for in all sections of your exam.The examiner reports state that students regularly overlook this area of the syllabus,so make sure you cover it during your studies.
Role of IS
Information systems are the backbone of a modern company.IS enables communication,sales and marketing,supply chain management,decision-making,employee management,process improvement and much more.Once considered a tool to improve efficiency,IS is now considered an important source of competitive advantage.
Think of a successful company you’ve recently read about or interacted with,and chances are you can also think of an example of how that company uses IS to distinguish itself from the competition.You can probably think of ways IS has changed the way you prepare for your ACCA exams-you might watch videos,take online courses,and participate in online forums.Moreover,you might have learned of these solutions through targeted advertising in your social media.
First,make sure you are familiar with some of the basic terminology in this area for your PM exam:
Internet vs Intranet
The term‘internet’describes the global network of computers and devices that are all connected with an Internet Protocol(‘IP’)address.I’m sure you are familiar with this and use it regularly to browse content on the web,for example,reading this article,accessing social media,and using many of the apps on your smartphone.
‘Intranet’refers to a subset of the internet that is blocked off from the public and only available to a certain organisation.For example,a university might have a‘private’web portal where students can log in with a username and password and then see their schedules,access student message boards,or upload their assignments.
Networks【点击免费下载>>>更多ACCA学习相关资料】
A‘network’is a group of computer systems that communicate by physical and/or wireless connections.The wifi router you might have in your home is connected to the internet with a physical cable,and it then allows computers in your home to connect through the wireless network that it broadcasts.
Wireless technology
Wireless technology is a fast-growing area of technology.As its name implies,it refers to communication without cables.Moreover,you are probably interacting with wireless technology regularly.You might connect headphones,fitness trackers or other devices to your smartphone with Bluetooth,the car you drive might use Radio Frequency ID(RFID)tags embedded on individual components to monitor maintenance and repair history,and the shipping company that delivers parcels to your home is probably using a variety of these technologies to track packages and monitor performance.
Categories of IS
Ensure that you understand and can distinguish between different types of information systems.While the latest developments in cloud computing,performance dashboards,and big data bring in new terminology and concepts,the following classic IS ideas form a starting place and are required knowledge for your PM exam.
翻译参考
信息系统(IS)对绩效管理(PM)至关重要。信息系统极大地有助于定义、衡量和监控绩效指标，并将它们与目标和基准进行比较。这是您在考试的所有部分都需要准备的主题。考官报告指出，学生经常忽略教学大纲的这一部分，因此请确保在学习期间涵盖它。
信息系统的作用
信息系统是现代公司的支柱。IS支持沟通、销售和营销、供应链管理、决策、员工管理、流程改进等等。曾经被认为是提高效率的工具，现在被认为是竞争优势的重要来源。
想想您最近读过或与之互动的一家成功公司，您可能还可以想出一个示例，说明该公司如何使用IS将自己与竞争对手区分开来。您可能会想到IS改变了您准备ACCA考试的方式——您可以观看视频、参加在线课程和参加在线论坛。此外，您可能已经通过社交媒体中的有针对性的广告了解到这些解决方案。
首先，请确保您熟悉PM考试中该领域的一些基本术语：
互联网与内联网
术语“互联网”描述了通过互联网协议(“IP”)地址连接的计算机和设备的全球网络。我相信您对此很熟悉，并经常使用它来浏览网络上的内容，例如阅读本文、访问社交媒体以及使用智能手机上的许多应用程序。
“内联网”是指互联网的一个子集，与公众隔绝，仅对特定组织可用。例如，一所大学可能有一个“私人”门户网站，学生可以在其中使用用户名和密码登录，然后查看他们的日程安排、访问学生留言板或上传他们的作业。
网络
“网络”是一组通过物理和/或无线连接进行通信的计算机系统。您家中可能拥有的wifi路由器通过物理电缆连接到互联网，然后它允许您家中的计算机通过它广播的无线网络进行连接。
无线技术
无线技术是一个快速发展的技术领域。顾名思义，它是指无需电缆的通信。此外，您可能经常与无线技术进行交互。您可以使用蓝牙将耳机、健身追踪器或其他设备连接到您的智能手机，您驾驶的汽车可能使用嵌入在各个组件上的射频ID(RFID)标签来监控维护和维修历史，以及将包裹运送到您家的运输公司可能正在使用各种这些技术来跟踪包和监控性能。
