When companies come to us (thick RFP documents under their arms), most of them want a system that is very flexible so they can change it as they see fit. Take for example the homepage of their webshop: it contains banners with large images, titles, subtitles, product images with product information and everything should be changeable in size, location, format etc. etc. maximum flexibility so the marketing department can change it all according to their current marketing and promotional ideas.
So far so good. By far the best way to accomplish this is to make a HTML page, maybe some basic layout columns or rows and let the client fill those with their data. Maximum flexibility for the client.
But when you talk to them or read further in their RFP there is almost always the next (implicit or explicit) requirement: “anyone at our company should be able to manage the website through the backend, even without any technical (html,css,php) knowledge”.
Well dear RFP writers: these two requirements don’t match. You can’t expect users without any technical knowledge to have maximum control over a technical system.
Even that second requirement on it’s own is actually quite a silly one. When you have a transportation business looking for new trucks, do you require the truck manufacturer to deliver trucks that everyone without a drivers license can drive? If you have large complicated machines in your factory, don’t you put your new employees through thorough training sessions before they are allowed to even come near the machines? Don’t you think that the medical people operating the MRI machine at your hospital to have had extensive training to operate the machine and interpret the results? You think any soldier just sits down in an Apache helicopter and flies away?
No. You don’t.
So why on earth do you expect that the person that answers your phone, does your accounting or designs your banners to operate your webshop right out of the box?
Of course IT companies can go a long way in making things automatic and flexible, but you can save a lot of money if you also invest in having people that are capable of doing things themselves instead of needing to call the IT company for everything they need or overdeveloping systems to make them nitwit-proof.
Running a serious e-commerce business requires you to have a team of employees that are (well) trained in several areas. Besides product managers, you’ll need people to be able to create online marketing materials (designer), optimization experts (testing/SEO/SEM), content writers (text writing and some basic HTML/CSS skills) and someone to lead this team to prioritize and keep your site moving forward. The bigger your site, the more specialisations you’ll have and you want to have the knowledge for all the recurring tasks in-home as quickly as possible. It’s ok to outsource if you can’t find additional people in your area or to add to your growth. It’s not ok to outsource if you don’t have the knowledge in-house.
Of course the IT company will be happy to take your money and write more code for you. But more code won’t make you more flexible. Investing in smart and trained employees will.
Recently I've seen some (often absolute) statements going around, generally in the line of "open source commerce platforms are a terrible idea". Now of course different solutions always have different pros and cons.
A hierarchy of evidence (or levels of evidence) is a heuristic used to rank the relative strength of results obtained from scientific research. I've created a version of this chart/pyramid applied to CRO which you can see below. It contains the options we have as optimizers and tools and methods we often use to gather data.
