A partnership that drives e-shop Top-obaly.cz
annual revenue growth of 40%
For over ten years we have been continuously improving the e‑shop and making it easier for its customers to shop. Our project management is supported by ongoing research, diligent backlog management, regular status calls and an annual roadmap.


Back then, Top‑obaly.cz had an e-shop built on an off-the-shelf solution that was no longer meeting their needs. They approached us needing urgent fixes and with the outlook that we would continue working on further e-shop development.
In 2015 we launched the website that is still running today. And we keep developing it.
Right from the start it was clear this would be a long-term partnership. Planning came next, initially on an annual basis. We met and put together requirements and plans for what would be worked on over the next 12 months.
Over time it became clear this method wasn’t working. Continuous planning was needed – having an annual outlook while also responding to current needs.
„Even while putting the annual plan together, both we and Top-obaly suspected we wouldn’t manage to fulfil it 100%. Over time, it became just tasks on paper.“

To plan long-term and have clearly defined collaboration goals, we still put together an annual plan. Long-term planning is complemented by regular meetings that help us stay on track and discuss new tasks.
„The annual plan is the main compass setting the direction of what we need to do. It allows us to plan the work and capacity of developers and other Proof & Reason team members in advance. Regular weekly status calls then allow us to be more flexible.“

The foundation of planning and collaboration with Top-obaly.cz is a backlog from which a regularly updated plan is created.
We record all ideas that come in:
„While Top-obaly.cz come with business requirements or problems that customer support deals with, we bring ideas mainly for improving the customer journey, conversion rate optimisation and speed.
We also continuously update technologies to reduce technical debt and keep the e-shop secure and fast.“

From the ideas, we need to select those that are a priority and will be addressed first. We consider:
We validate every idea with data from our own research or external studies. This reduces the risk that the client would invest in a solution that ultimately wouldn’t work.
We then design the solution and estimate its complexity. The principle of describing ideas is based on the method Shape Up by Basecamp. For each idea we prepare a description that includes:

„Proof & Reason considers above all whether the solution will work and deliver what we expect from it. We select the needs with the greatest business benefit. Together we determine priorities and decide what to tackle.“

In addition to the annual planning meeting, we have found regular video calls, known as status calls, to be invaluable. A call with the client, at which only the project manager from Proof & Reason is usually present, or someone else from the team when their expertise is needed.
Regular calls last up to half an hour and we manage to cover:

„Status calls are a small thing, but essential for the partnership. They’re great for task visibility – nothing slips through the cracks. Plus, regular meetings are important for maintaining contact with the client.“
We don’t wait for status calls with urgent problems and needs. If a bug appears on the e‑shop, we fix it immediately.
The way we manage the collaboration has evolved gradually – from an almost unstructured stream of tasks to today’s system of collecting ideas, prioritising them and communicating regularly with the client.
We’ve set up the entire process to suit both sides and we continuously improve it. This helps us work as one team with Top-obaly.cz, not as client and vendor. We see their passion and drive to improve the project.
We cover the collaboration with Top-obaly.cz in more detail in an article on our blog.
„I’m glad that the collaboration with Proof & Reason keeps getting better. I welcome that they come up with ideas on how to manage the project even better. It’s then enjoyable for both sides.“
