The part where you mentioned getting the right concept, ui, design, implementation, debugging and documentation. Like any craft there's still a supporting cast of skills that helps drive the main function (eg. singers have sound engineers, ghostwriters to focus on the song to the audience, etc. Same with movie making there's the actor but a long supporting list of people around that movie)
