Working on automating processes to be even better! How? 💡 - By using #Redmine as our project management system. Redmine is an open-source application with a modular architecture that plugins can extend. We use Redmine plugins to add functionality that is not present in Redmine Core. Plugins allow us to extend basic functionality and make cross-system integrations. - For example, when a person sets time off in Redmine, it should be automatically added to the person’s Office365 calendar and also reflected as the Mattermost user status, so others see this information in the IM communicator when they try to reach out to the unavailable person. The latest internal #hackathon, where members of the R&D Backend and Web Frontend teams met to increase our work efficiency, was all about real-time collaboration, coding, and pizza! The main goal was to automate selected internal processes and parts of our daily agenda. 🍕🤝 Check the article in the comments for other tips on automating internal processes that might be helpful in your workplace. ✌️

INTERVIEW SCAM ALERT! I want to share an important observation with my network. Over the past few days, we conducted several interviews where candidates were required to build a frontend app using CodeSandbox in a live challenge. We noticed a concerning pattern among three candidates who shared the same ethnicity and were all located in Poland. Upon opening CodeSandbox, a flag appeared indicating "Companion Mode." This feature allows for live or pair programming, enabling someone else to code alongside the candidate. During one of the interviews, it became evident that the candidate was struggling to set things up. We realized they were cheating by having someone else assist them through Companion Mode. Consequently, we terminated the interview. If you use CodeSandbox for your interviews, I strongly suggest stopping the interview immediately if you see the "Companion Mode" flag. Additionally, performing thorough background checks on previous companies and obtaining feedback from referrals has become essential. After blowing off someone's cover this afternoon, the profile of one of the three guys has been removed from Linkedin. I hope this information helps other companies avoid similar issues.

We don't offer software development outsourcing services, and that's a huge advantage. It is another model we do not currently offer at all! Unlike many others, we avoid conflicts of interest with our clients. Picture a typical situation for many providers mixing “team extension” and “high-value software development” services: They find a great software engineering team lead, let's say with a strong Java background and a very attractive rate, and their client needs such a professional through the team extension model as soon as possible. This seems great, but if the vendor is simultaneously developing a product on the outsourcing model for someone else where Java (lead) is needed, they may be tempted to keep this expert for themselves instead of offering them to the first client for whom the actual search was launched. A conflict of interest at its core - competition for the talent between a client and a provider working on “another model” for “another client”. By putting the right talent to the former, the Vendor earns their standard fee. By taking one for themselves, their margin skyrockets on that other project. Would it be an easy choice for you to make? We avoid this to guarantee the most transparent and straightforward cooperation possible. So should you - ask your potential vendor how they treat cases like this and if it’s even possible for them. Cheers!

Last Friday we talked about Hardware budget, let's talk on Software development budget this time. Can that be reduced by dividing by a single-digit factor? Yes, it can :) If you are a customer and you have accepted a development budget prepared by the developer, the cost of your error is a multiplier greater than 1 and less than 10, built into such a budget. Our top record is 5. The budget was reduced by 5 times without changing the functionality. The customer received a budget from the market at 200 thousand dollars, and after critically reviewing the architecture, the same developers were ready to work for 40. Let's start with an analogy: if you entrust a contractor to design a building, you can be fairly certain that many leftover materials from the contractor’s warehouse will find their place in the project, even if all these "excesses" are not really needed by the customer. For a software developer, such a warehouse is a "repository" – a specialized storage of previously written code, placed within the developer’s internal server. Any developer has an additional incentive to use the code written by it as often as possible. The incentive is the significantly lower man-hours required to adapt such code for each new project compared to writing this functionality from scratch. Also, a repository allows developer to sell the same functionality multiple times. This is a very powerful mechanism for increasing profitability when performing custom projects, and you can't blame a contractor for trying to maximize their profit. For example, creating an authentication and authorization service may be estimated by a developer at 1800-2000 hours. A budget check on the market – requesting an estimate from other developers – will show a "hit" in the average estimates for creating such functionality. But by using their own repository (assuming service was implemented before), developer will actually spend 150 hours instead of 2000, and all the rest honestly becomes its profit. Just in one project out of few, where that service can be sold to customer :) Of course, the correct answer is that such a service should not be written from scratch at all; there are several excellent open-source options that, if chosen by customer, can be adapted in 50 hours, ie KeyCloak. But to do this, someone on the customer’s side must know about the existence of alternatives and be able to choose them. The moral is again simple – such collisions can be avoided by dividing roles between the performers involved in the project, for example, architect and developer. Then the architecture of the future solution is handled by a separate participant that does not earn money from the hours of development sold to the customer. All it takes is common sense from the customer when managing a software development project. Image source: https://lnkd.in/dRrZBH9k

Are they making software? Yes TH-EY are! I am more than happy to welcome another software agency that decided to switch to Apropo for #estimating their projects - please give a round of applause to TH-EY! 👏 👏 👏 TH-EY is (or shall I say “are”?) a custom software development company with HQ in London and Krakow, specialized in building web & mobile applications for companies from the #UK, #US, #Canada and #Western_Europe 👈 They are also one of the client-#ROI-oriented companies - they first work out the problem on a paper and only then fit the best technology into it, regardless of whether that's a clickable design prototype, #MVP, or a fully-fledged custom software product 💡 👉 I’m very happy to see such approach, especially that I’ve written about it in one of my recent posts (link in the comments). 👉 TH-EY switched to Apropo in search for a tool that would make their estimates faster, more accurate and more transparent for their clients. 👉 Here is how Filip Kubala, Founder at TH-EY, comments the results of implementing Apropo: "𝘌𝘴𝘵𝘪𝘮𝘢𝘵𝘪𝘰𝘯𝘴 𝘭𝘰𝘰𝘬 𝘸𝘢𝘺 𝘮𝘰𝘳𝘦 𝘱𝘳𝘰𝘧𝘦𝘴𝘴𝘪𝘰𝘯𝘢𝘭. 𝙊𝙪𝙧 𝙘𝙡𝙞𝙚𝙣𝙩𝙨 𝙡𝙤𝙫𝙚 𝘵𝘩𝘦 𝘤𝘭𝘢𝘳𝘪𝘵𝘺 𝘢𝘯𝘥 𝘵𝘩𝘦 𝘢𝘣𝘪𝘭𝘪𝘵𝘺 𝘵𝘰 𝘱𝘭𝘢𝘺 𝘸𝘪𝘵𝘩 𝘲𝘶𝘰𝘵𝘦𝘴 𝘰𝘯 𝘵𝘩𝘦𝘪𝘳 𝘰𝘸𝘯.
