Plan. Produce. Position. Proof.
Planning is 20%. Producing is 40%. Positioning is 30%, and that last remaining bit is 10% for Proof. All together that makes up 100% of a project. Is a project exactly like that every time? Of course not. These proportions work for allocating effort, budget and hours. This exercise forces an awareness that a project is not all producing. Putting the content 'somewhere' and measuring how that content 'works' are also important.
Understanding what that last ten percent means is important for production. It means that something as basic as including the Google analytics script on each page is a requirement. Which in turn means having an analytics account and understanding just what can be done with this analytics package from Google. So the end (proof) requires something to happen in production and ideally is also part of the plan.
It's all connected.
Having a '4Ps' framework is handy, because it serves to remind everyone involved of the bigger project picture and how one issue may inform on another.
Framework. Priorities. Resources. What content do we have? What do we need to create in order to make the page? Visibility. File Naming Rules anyone?
In the fiction writing world, there's two camps - the 'pantsers' and the 'plotters'. The 'pantsers', as you might intuit, favor writing 'by the seat of their pants'. They write their fiction in a stream of conscious, somewhat chaotic manner. The belief is that this encourages some sort of creativity. And it may well do that, especially if that is your flavor of personality.
'Plotters', on the other hand, sit down and make an outline first. Once that is complete, they go back and write the content that fits the first entry in their outline. Much more logical and orderly, fewer things are missed. Efficient, but still not perfect. Even the best plotter will happen up on an event and recognize that some detail was not included in the outline. This of course forces a revision or a redo or at least a revisit of the outline. Any of which is OK. Better to catch a detail late than never right?
It doesn't matter which style you may prefer. They both work and each fits a certain personlaity type. More importantly though, both styles still end up circling back and revising, adding detail and changing the 'plan' to accomodate unforeseen details. Even the best plan is imperfect. Some bit of revision is part of progress.
Website construction or revision is not the same as writing fiction. While creativity is important in business, one generally goes about marketing a business in a bit more orderly manner. Change and modification are still part of the process. Defining the details and being explicit about 'what' goes 'where' and 'what the 'what exactly is, tends to bring out those missed details. Is there a picture of this product? Do we have copy written for a detailed product description?
As always, answering those questions makes the project better and more complete.
