Knowledge workers carry out these processes by taking into account multiple inputs (generally a wide set of unstructured data and information) to perform difficult tasks and make complex decisions among multiple possible ways of doing the work, each one implying different levels of risk and possible benefits. They are dependent on individuals and it is not possible to automate them. One example of a knowledge process is "Marketing a new product". The same steps are followed each time a new product is launched (benchmarking competitors, deciding pricing strategy, planning promotion, etc...), but it is the experience, knowledge and intuition of the people that drive the process to success.
For a technical writer a flowchart can be a very useful tool to illustrate various operations and processes. Before you start your next project, see if you can illustrate the process via a flowchart. It will make life easier for you and your manager or client. The end result will be a better project which is good for your target audience. Note: Microsoft Visio is a good software for creating flowcharts. If you can write a simple sentence in English and organize your thoughts then technical writing may be a rewarding field. You can easily make it a second income stream in your spare time.
