On a broader scale, web development includes the process of web designing, as the development of a website will include the process of designing. But the skills that a professional needs for web development jobs are different than those for web designing work. Still we will say that it is a brotherhood of professionals as one cannot live without the other.

Like in a brotherhood, every member will have a defined role in the organization, so does every person in a web development organization. There will be developers as well as designers who will be skill-ready for professional work in their own domains. Like in a Venn diagram these domains may overlap at some functions but majorly remain different. They need to maintain an understanding of each other's capabilities as well as roles.

The term web designing is generally given to the design process relating to the front-end (client side) design of a website including writing mark up, and this is the grey area which causes troubles in the brotherhood. As it is the responsibility of both the web designing and web development teams. The back-end (user side) is solely handled by the developer and the work is generally not seen by the client other than the functionality which the user will feel and observe.

Very similar to human brain the web development and web designing are the two sides which together form a good website development organization. They need to work together with synchronization and understanding so as to reduce the work load and increase the throughput of the organization. If there is some communication gap or misunderstanding between two teams then the resultant production could be really bad design and functionality of the website.

The look is governed by the designer whereas the fell is governed by the developer. The users interaction while observing the graphics, images, designs, etc. is affected by the skill level of the web designing which has been done on the website. Whereas the client's experience with the features, working, user-experience, etc. will be governed by the development teams skills. When both of them work in unity they produce marvels which are a delight to the user as well as the client, to the customers as well as the customers
