Now that we have wrapped up Perspective 4 around Business rules and had our special bonus interview with Robert Thacker on Process Mining and Process Automation, it’s now time to talk about Perspective 5: The Systems. If you have missed the previous Perspectives you can find them on my blog.
First, we should start with defining what a system is for the purpose of this perspective. If you have ever studied the concept of systems thinking, you know a system is defined as more than just technology. A system in the context of systems thinking consists of interacting, interrelated and interdependent components to form a complete whole. So, a system is made up of many components, not just technology. A system consists of the organization culture, framework, processes, resources, technology and more. However, for the context of this perspective we will be focusing on technology. We will focus on what a system is from the standpoint of technology, how systems work independently and with other systems, how to identify systems, why having this knowledge is important, and finally we will wrap up with the system context diagram technique as a way to visualize systems.
Before we get started there is one item I do want to address. There may be some of you reading this post that are business analysts, and I want to address a question I receive a lot from business analysts in regards to, what technologies do you have to know in order to be a successful business analyst. My answer to that question is, it depends! There is no way you can learn every single technology/software language out there. You will lose your mind. It is just not a realistic goal, and you will swirl forever trying to keep up. However, there is some reflection you can leverage to determine (1) do you need to know certain technologies to be successful in a certain industry? (2) What technologies do you need to know to be successful in your role if that is required? (3) Do I want to work in an environment as a business analyst where I have to be a technical business analyst? Here are some reflections to consider:
As you can see, there is no black and white answer to this. Actually, there can be quite a bit of grey. It boils down to the needs of the organization, and the organizations expectation of certain roles. It can even depend on where you reside geographically, as some geographies have different requirements.
Now that I have addressed that question, let’s go a little deeper into Perspective 5.
What is a System
As stated earlier, when I reference systems for this perspective, I am specifically referencing the technology systems, or applications organizations use to deliver services to their customers. Examples, could be user interfaces, mainframes, databases, artificial intelligence, robotics, and more. Now, the complexity comes with understanding what the systems are, what the systems do, how the systems interact with other systems, or if they are a stand-alone system. Every organization has a system of some kind leveraged to deliver services. Sometimes finding out what those systems are, and how they are used is challenging, but it can be done.
How Does a System Work?
A system helps to deliver some type of a capability/service to an end user/consumer. Input(s) trigger the system to perform some sort of task. In some instances, there may be other systems (sub systems) that are leveraged by the main system to complete the task. In most cases there are also controls in place to ensure the service functions as expected. Once the task is completed some sort of output is rendered which delivers some sort of capability to the end user/customer. The diagram below depicts what this might look like visually.
To give an example to bring this to life. Most of us have some type of bank product.
Let us take your checking account as an example and say you want to deposit a check you received via your phone to your checking account. Here is what the system may look like to deliver this service outlining the components above in the diagram:
Input(s): Phone and check
System: Mobile Banking System
Sub System(s): Customer Management System, Deposit System, Phone Mobile App
Controls: Authentication of customer prior to access to the mobile banking system
Output: Confirmation message check was electronically deposited into account
Capability: Allows customer to deposit checks through their mobile phone
This is just an example on how a system works and interacts with other systems. Knowing this type of information is great because it can help you understand capabilities that already exists, capabilities that may not exist that can deliver a better service to the customer, and much more.
Now that we understand what a system is and how it works, in my next post we will discuss how to identify systems and why knowing our systems is important to the overall organization.
