7 Our goals This experiment around AI technologies applied to the developer profession had as a goal to demonstrate that we can : ➔ Achieve productivity gains due to time saving and increase our profitability ➔ Be as competitive as our competitors if not more so by being ahead 05 I.T IS OPEN 

8 Our goals But it also serve as our continuous engagement to ➔ Provide quality tools, software and hardware to our employees ➔ support them in this profound transformation of their profession ➔ explore what’s the future of work could be 06 I.T IS OPEN

But which metric to look at? 10 I.T IS OPEN 

Check-in attendance 13 It’s super hard to gather datas by just asking developers how they feel about the tools, what they did over the last period, etc. 11 I.T IS OPEN 

What feature they are using 14 The more the feature is automagically pushed to the developer, the more likely they will use it. 12 I.T IS OPEN

Results 17 I.T IS OPEN 

20 Our results & learnings 80% Of the developers notices time savings using the tool 10 Of AI generated code or documentation is approved by the developer 15% Overall productivity increase on the project 60% Of collaborators can’t imagine step back on AI 80% ● Higher automation potential than expected. ● Tool aids developers in writing code faster without fully replacing their work. ● Side effect of quality improvement by developers documenting the code and writing unit tests ● Side effect on experts sollicitation, NPS, SLA on projects, HR satisfaction with new tool 39% Time improvement on new code writing 18 I.T IS OPEN

How to evaluate solutions? 21 I.T IS OPEN 

Our main criteria of evaluation 22 1 2 3 Covers relevant required IDEs & languages State of the art LLM model High security and privacy standard 4 5 6 Covers the most relevant use cases Popular, evolutive with no deprecation risk Easy adoption & use, quick go-live & revert We have a wide range of IDE used at Smile, so we needed a solution that could work not only on one solution. Some solutions offer more than just code completion or chat, but is it useful to you? Can you use all of those functions you’ll end up pay for? A lot of open-source solutions let you integrate any kind of LLM you want. However, a lot of them aren’t designed for code generation. Nothing worse than spending time and investing money on a solution that just die a couple of months after you rolled it out. Solution editor will have access to all your project data (prompt, code context, workspace, generated code). You better want to protect this. If we are doomed to fail, better fail fast, recover fast and find another solution. 24 I.T IS OPEN

27 Reference tracking Why Tabnine ? Security & Compliance Generated code is provided with its source, so the developer can see it used threw an other context and qualify it for its own need. Tabnine is committed to security and compliance. They are GDPR compliant, certified ISO9001 & AICPA SOC. They are expected to meet the EUAI Act when enforceable. IP indemnification Admin tool for tracking The data used to train Tabnine comes from permissive licenses, ensuring the tool’s use does not pose legal risks related to copyright. They are offering indemnification in case of legal issues. Tabnine provide admin tools for tracking usage and user productivity Private SaaS or on Premise And many more technical reasons Tabnine models can be deployed on private cloud infrastructure in our clients if required 01 25 LLM 4DEV 

How we’ll roll it out? 27 I.T IS OPEN 

30 Senior developers and AI interested people can masterize pretty fast the tool usage. Junior ones need continuous support to grow and discover the tool. Learning is flat on the first month and progressively grow after that. We designed a roll out plan 1 week Start 3 weeks Skill Development 2 months Onboarding Initial Use Open talk with Tabnine support Bi-weekly follow-up This 4 months curve is the time to get a developper ready and meet the experiment results. Onboarding session by Tabnine First use Discovery of the tool capabilities. Main usage is code autocompletion and basic features Developers starts showing productivity gains 1 month Productivity unchanged due to time losses by exploring the tool potential Internal Certification AI Beginner Internal Certification AI Explorer Internal Certification AI Developer Weekly follow-up 28 I.T IS OPEN 

31 Accordingly to the experiment, the deployment first wave is targeting Drupal based new engagements. Depending on project’s launches and according to the commercial pipe, the first wave could be extended to other technologies like Front-end / Javascript projects. Deployment & next step First wave Drupal new engagements 1st wave 2nd wave 3rd wave Train Tabnine on solutions Smile Private Chat LLM Bring AI tools for other tasks in a project lifecycle with a Smile secured internal LLM chat (Chat GPT like). Ongoing ßeta test at neopixl. Expected productivity increase on tasks like specifications writing, QA test cases, reporting and many more. Tabnine can be trained by our own Smile Knowledge and best practices on solutions like Adobe Commerce that are not easy to handle by a native AI model. Initial deployment on Drupal based projects and potentially extended to technologies which have proved good results during the experiment Potential deployment on specific new solutions that have been learnt by Tabnine. Deployment on specific development technologies like Symfony, Java or other eligible solutions. 29 I.T IS OPEN 

Some important things to keep in mind 30 I.T IS OPEN 

Our initial thoughts 31 1 2 4 AI won’t do everything alone Enhance, not replace You need people to constantly monitor it 4 5 You need to monitor the model production too Get ready to adapt your protocol all the time We have to keep humans in the loop and make clever decisions from what is proposed by AI It's also crucial to monitor quality of the output from the LLM because it can be hallucinated suggestions or garbage The goal is to make the developers' jobs easier and more efficient, not to replace them. It’s moving fast and improves everyday. Don’t fall for FOMO. Always seek feedback from the team and adjust our approach based on their experiences and needs. 33 I.T IS OPEN 

Developers are fed by FUD from the medias. You’ll need a lot of acculturation and kindness to overcome it. What changed 32 1 2 4 AI won’t do everything alone Acknowledge the fear of change Your developers have HUGE biais 4 5 6 Code prediction isn’t the challenge You’ll be too slow for everyone It’s not just about developers We have to keep humans in the loop and make clever decisions from what is proposed by AI. Most of the model are okay~ish to predict code on the flow. But being able to handle more complex request is key. From your exco to your developers, everyone will be so eager to use that new tech they will find you slow. But that’s how you’ll be able to win the game. Asking what tool they prefer using will not be sufficient. A lot of our developers love Github Copilot while it’s not making them as much productive as other tools. That’s an obvious one, but that kind of first experiment will unlock dozen of new use cases that are affecting more jobs than just developers. Get ready to handle it. 34 I.T IS OPEN
