while reviewing one of the older projects that was currently implemented in the company I noticed that there was no alerting in place if the data pipeline breaks, the data pipeline has never been broken and it never failed for the last 2 years. it was a pipeline where the data would be dropped into an sftp bucket by the customer every hour and then it was moved to an s3 bucket where s3 triggers were implemented to moved the data in to queue. So in case there is an issue with the data not being processed we would only know when the we see a drop in volume. I identified it as a potential issue with the system and worked on a proposal to have monitoring in place so we are notified when there is an error. I worked with the program manager and devised a plan on how to implement the alerting and the time lines as well as the effort that will be needed to implement it. I mapped the impact of not having it to the current goals of the company and then put forward a proposal of implementing the alerts to the business and took their buyins. after getting the buyins I proposed the task to my team and some of the sr devlopers were not too keen on implenting the alerts, I gave the task to some of the Jr devlopers and the alerts were implemented. after the implementation we discovered that for some hrs in a day we werent getting any files so instead of getting 24 files in a day we were getting 20 files a day in an average. This was rectified by talking to the customer and the missing data was solved. but this made the whole team realize the importance of monitoring and alerting. It also bosted the moral of the Jr developers seeing the direct impact they made to the business goals

I’m my current role, during a core-team meeting I noticed conflicts between 2 team members, the MM and the EE. They were debating about why to include one component in the official BOM and discarding another one.

To understand their perspectives, I spoke with them separately in a friendly environment. The MM was frustrated because the EE didn’t provide any data or argument to discard the component that the MM suggested. This component had the same performance, was pin to pin compatible, and cheaper. On the other hand the EE explained he had bad experiences in the past with the component suggested by the MM and he refused to validate and qualify it to do not waste his time.

So… After being clear about the situation, I brought them together for a discussion and I emphasize to focus on the issue, not in personal discrepancies. Do, during the meeting, I encouraged both to consider the Project requirements, customers need and I worked with them brainstorming session.

Then, they agreed to meet with other stakeholders to get their inputs about these 2 components, they commit on a validation plan including both components. The one suggested by the EE as POR and the one suggested by the MM as alternate. They also agree to allocate 60% of the mass production volume to the EE component and 40% to the component suggested by the MM.

From my side, to ensure progress, I scheduled follow-up meetings with them to monitor their collaboration and for sure, I offered my support. Finally, both components are currently part of the product official BOM and these 2 guys improved their working relationship and communication.
