    I think it can serve the whole spectrum of experiences from people who are just getting used to web experimentation. It's really easy to pick up and use. If you're more experienced then it works well because it just gets out of the way and lets you really focus on the experimentation side of things. So yeah, strongly recommend. I think it is well suited both to small businesses and large enterprises as well. I think it's got a really low barrier to entry. It's very easy to integrate on your website and get results quickly. Likewise, if you are a big business, it's incrementally adoptable, so you can start out with one component of optimizing and you can build there and start to build in things like data CMS to augment experimentation as well. So it's got a really strong a pathway to grow your MarTech platform if you're a small company or a big company.

    For teams or individuals with lots of individual tasks/details to track, Trello is perfect! It basically removes the need for a paper checklist. For those that need an overall project management tool that requires less tasks and more overarching goals, collaboration amongst various teams, and gantt charts I would suggest monday.com

    Cons
    Optimizely
    • JavaScript is hard to implement sometimes especially for JQuery elements
    • ROI reporting should be part of the overall experimentation reporting
    • CMP integration: where we can easily show status of test on the HPT request
    • CMS integration
    • More widgets like social proof banners, etc.

    • Also as a visual thinker I would like to be able to easily add images to cards.

    I rated this question because at this stage, Optimizely does most everything we need so I don't foresee a need to migrate to a new tool. We have the infrastructure already in place and it is a sizeable lift to pivot to another tool with no guarantee that it will work as good or even better than Optimizely

    I am very likely to renew Trello, because it doesn't cost anything to do so. I am also very likely to use Trello's upgraded features in the future because a lot of my team's data is stored on there and they have already gotten used to the platform. Trello is very easy for new team members to pick up, making the onboarding and usability very streamlined.

    Usability
    Optimizely
    Optimizely Web Experimentation's visual editor is handy for non-technical or quick iterative testing. When it comes to content changes it's as easy as going into wordpress, clicking around, and then seeing your changes live--what you see is what you get. The preview and approval process for sharing built experiments is also handy for sharing experiments across teams for QA purposes or otherwise.

    Trello is incredibly intuitive, both on desktop and mobile right away. It is also full of helpful features that make it even easier to use, and is flexible enough to suit almost any organizational need. Onboarding for the software is thorough, but concise, and the service is frequently updated with even more QOL improvements.

    I haven't reached out to their support very often and their support is very limited anyway for the free users. They do have tons of great articles and videos in their Help Center and constantly send emails with updates and add-ons to the product. The fact that I've barely ever had to contact their support team means that they've developed a great product.

    The tool itself is not very difficult to use so training was not very useful in my opinion. It did not also account for success events more complex than a click (which my company being ecommerce is looking to examine more than a mere click).

    In retrospect: - I think I should have stressed more demo's / workshopping with the Optimizely team at the start. I felt too confident during demo stages, and when came time to actually start, I was a bit lost. (The answer is likely I should have had them on-hand for our first install.. they offered but I thought I was OK.) - Really getting an understanding / asking them prior to install of how to make it really work for checkout pages / one that uses dynamic content or user interaction to determine what the UI does. Could have saved some time by addressing this at the beginning, as some things we needed to create on our site for Optimizely to "use" as a trigger for the variation test. - Having a number of planned/hoped-for tests already in-hand before working with Optimizely team. Sharing those thoughts with them would likely have started conversations on additional things we needed to do to make them work (rather than figuring that out during the actual builds). Since I had development time available, I could have added more things to the baseline installation since my developers were already "looking under the hood" of the site.

    For our small business, getting a few of us started well on Trello was the key, I think. As long as a couple of us were really comfortable with the interface, we could lead others and help them with any questions. From now on, anyone who works with us just naturally uses Trello for information sharing - it's just part of what we do.

    The ability to do A/B testing in Optimizely along with the associated statistical modelling and audience segmentation means it is a much better solution than using something like Google Analytics were a lot more effort is required to identify and isolate the specific data you need to confidently make changes

    Trello is more simple and not as "robust" as the other tools, but it's easier to use and manage and understand and ACTUALLY get stuff done with. It's simplicity is part of the beauty of using it. You don't need a million options that nobody uses, you just need to get stuff done.

    We can use it flexibly across lines of business and have it in use across two departments. We have different use cases and slightly different outcomes, but can unify our results based on impact to the bottom line. Finally, we can generate value from anywhere in the org for any stakeholders as needed.

    • We're able to share definitive annualized revenue projections with our team, showing what would happen if we put a test into Production
    • Showing the results of a test on a new page or feature prior to full implementation on a site saves developer time (if a test proves the new element doesn't deliver a significant improvement.
    • Making a change via the WYSIWYG interface allows us to see multiple changes without developer intervention.

    • Trello keeps me organized, focused, and on track. I could filter the Trello board to only see my issues and understand what I needed to work on and when.
    • Trello helped our team implement an agile structure. It's a very simple kanban method of viewing all of your team's tasks and statuses. You can completely customize the columns to your team's specific workflow and create tags relevant to your work.
    • Trello helps reduce unnecessary communications between teams. When I want to request translations, I simply create a card on the localization Trello board -- no need to directly message anyone on the team, and I can watch the status of the card change from "in progress" to "in review" to "translated," all without having to directly ask for updates.
