1. It is important for manuals to be "easy to read".

Have you ever been given a manual by your boss or senior and thought, "I don't feel like reading this manual..."? Manuals like that tend to be read less and less over time.
Many companies are struggling with the fact that their business manuals are not being utilized. When we actually show them the manual, they often say, "Hmm, this must be difficult to read." Manuals like this tend to have the following characteristics:
・The text is densely written.
・Sentences are excessively long.
・Lacks visual contrast.
・Information is simply crammed together.
On the contrary, simply being aware of not making it this way will make the manual much easier to read. In order to make use of the manual, it is important to create a manual that is easy to read and makes the reader think "I want to read it", "I can read it", and "Let's read it". You may hear voices saying "I already know that!", but when you actually try to write a manual yourself, it is surprisingly difficult.
We will explain the points for creating easy-to-read manuals for everyone.
2. 3 Points for Creating an Easy-to-Read Manual

To create easy-to-read manuals that people want to read, the following three points are important.
①Improve the first impression
②Write from the reader's perspective
③Create headings
① Improve the first impression at a glance
A good visual impression can make the reader think, 'This manual looks easy to read.' Let's consider the following points.
・Add Contrast to the Layout
Make the title text larger and indent the body text to create contrast in the layout. For supplementary notes and warnings, decide on the icons and styles to be used, clearly distinguishing them from the main text. For example, when creating manuals in Word or PowerPoint, it is efficient to determine which styles to use for which information and include them in a template.
However, overusing icons or excessively coloring the text can lead to an overload of information unrelated to the content, making it difficult to read. Be careful not to over-decorate.
・Create Margins
When text is densely packed, readers may first think, "This looks difficult to read." Let's create appropriate margins on the page. By creating margins with the right balance, it becomes easier to understand the organization of information, and it can also help readers reach the necessary information more easily.
・Add Visual Elements
Using diagrams and images helps to facilitate visual understanding. For example, showing an actual image of a form along with a filled-out example will allow for quicker comprehension than explaining how to fill out the form with text alone.
Additionally, presenting information in a tabular format organizes the items and explanations, making them easier to read.
② Write from the reader's perspective
Here are two points to keep in mind when writing from the reader's perspective.
・Make it concise
When long sentences continue, the reader may feel overwhelmed, thinking, "Do I really have to read this to the end...?" Aim to make your writing concise, keeping each sentence to about 40-50 characters for a smoother reading experience.
If your explanations become lengthy, it often means you are cramming too many ideas into one sentence. Review and check your writing, and consider breaking it into multiple sentences or using bullet points. Additionally, texts with too many kanji can be difficult to read. A good ratio of kanji to hiragana is about 3 to 7.
・Explain in words that resonate with the reader
To consider content and expressions from the reader's perspective, it is important to concretely imagine the profile of the manual's readers (knowledge level, thinking, feelings, etc.). It may be helpful to envision the new employees who will be joining soon or junior colleagues in their second or third year.
When writing a manual, it is easy to want to add many pieces of information, thinking, "I want to supplement this" or "I want to explain that." However, if the reader is presented with information that exceeds their knowledge level, they will only become confused and understanding will not progress. Check whether the information is truly necessary for the target audience and whether you are using expressions that are too difficult, and explain in words that resonate with the reader.
③ Create a heading
Let's create headings to clearly define a set of information. Simply listing text makes it difficult to find the desired information.
Readers look for the necessary information from the headings. Let's use headings that intuitively convey the content of the text. For example, when explaining the procedure for heating using a machine, a heading like "Heating" is not as effective as "To Heat." The term "Heating" alone does not clarify whether it explains the mechanism of heating or the method of heating.
Does your manual meet the following points ① to ③?
If you feel that there are areas that are not up to par, please try to improve those points. You should be able to enhance it into a user-friendly manual that makes readers want to "read it."
