Comments from delegates There is something new to learn for most technical authors who are in the early stages of their career. Overall, I would say that the course did benefit me, and I can see myself revisiting parts of it in the future. Emma W., ARM plc I attended a job interview which included a written exercise where I had to jot down how I would go about designing and presenting information for the users of the service unit I was applying to. I could not believe my luck, it was as if the interviewer had designed it with the contents of this course in mind, and, as a result, I got the job! Amber A. I thought it was an excellent course – very thought-provoking and useful. The exercises were enjoyable and really helped, far beyond simply reading from a book about the tasks involved in the job. And I greatly appreciate all your advice and support. Karl D. Thank you very much for all your feed-back – I’ve been reading through this as it has come in this morning. This is really useful and very much appreciated. David H. Who is this course for? This course is ideal for you if you need to: Create end-user documentation and other forms of instructional content with ease Master the fundamentals of technical writing Get a solid understanding of the Technical Author’s role. This course is ideal for more experienced technical writers who’ve never had any formal training. What is a Technical Author? Technical Authors are sometimes known as: Technical Communicators, Technical Writers, Content Developers, Information Developers and Documentarians. Based in the United States or mainland Europe? We've designed the course to work for people living all around the world. On the videos, you'll hear a lovely, clear British accent. What will I learn? In this course, we’ll take you through the process of creating technical documentation. You’ll learn and practise: The purpose and value of technical documentation (aka having an answer if people ask why you should be doing this work). The entire documentation process. We’ll explain what you need to do, from beginning to end. We cover planning, writing, editing, indexing, and production. The skills you need as a technical communicator. How to work more efficiently. This framework will help you avoid wasting time. How to work more effectively. We’ll show you how to write and design your information in a structured, useful, usable and informed way. We don’t like to overhype our courses, so here are some reasons why not to get our technical writing training course. Those are: If you have requirements for your documents to meet specific regulatory documentation standards in these industry sectors: aerospace, military, railway, or automotive. Where documentation must be written to a specific XML standard. (You’ll need to take our DITA module in our advanced course as well). If you need to write technical API documentation for developers. (You’ll need to take our API module in our advanced course as well). Apart from that, this course will help you create the user assistance for your application or product. Duration and delivery format The course comprises 15 modules in total, which you can complete at your own pace. The course modules are delivered over the Web in small, manageable video presentations. You can download the course handouts as Word or PDF files. With the time needed to complete the exercises, you will need to allocate around two days in order to complete the course. You can pause the videos at any time and return to the course at times that suit you.
