Subject: Consolidating Our Project Trackers into One Tool Hi Team, I’m pleased to share that we will be merging our two existing project trackers into a single, centralized tool. This change is intended to simplify how we plan, monitor, and communicate project work across the team. Using one tracker will give us a clearer view of priorities, ownership, timelines, dependencies, and progress. It should also reduce duplicate updates, minimize confusion about which source is current, and make reporting easier for everyone. Our goal is to create a more consistent, transparent workflow without adding unnecessary administrative work. Over the next two weeks, we will migrate active projects, open tasks, key milestones, and relevant documentation into the new tool. Please continue updating your current tracker as usual until you receive confirmation that your workstream has been moved. We will share a migration schedule, access instructions, and a short guide for the new setup shortly. To support the transition, we will hold optional training sessions and office hours for questions, feedback, and troubleshooting. Team leads will also review migrated items with their groups to ensure priorities, due dates, and owners are accurate. Once the migration is complete, the single tool will become our official source of truth for project status and planning. The existing trackers will remain available in read-only mode for a limited period before being archived. Thank you for your flexibility and support as we make this improvement. Please reach out to me or your team lead with any questions, concerns, or suggestions during the transition. Best, [Your Name]

How to read these scores

Each detector's result is converted to a human-likelihood score between 0 and 1. A score of 0 means the detector is sure the text is AI. A score of 1 means it is sure the text is human. Dots are green at 0.50 or above and red below. Hover a dot to see its exact score. The 0.50 cut-off only sets the dot colors. A tool's bypass rate on the leaderboard takes the median of the 7 detector scores for each test, then averages those medians. That gives a continuous number, so it will not match the share of green dots. The same goes for each per-detector rate. It is the average of that detector's scores (the number detector pages rank by), not a count of green dots.

Humanized outputs

Tools that passed more detectors come first. Ties are broken by overall rank this cycle. Each card shows the 7 detector scores, then the tool's rewrite.

Hello team, Hi Team, We are excited to announce that we will be consolidating our two current project trackers into one categorical base. This adjustment to how we plan, monitor and communicate project work across the team is intended to make these processes simpler. Having use one tracker will help us get more visibility on priorities, ownership, timelines, dependencies and progress. It should also reduce the number of times an update is repeated when keeping track of this information, it should help avoid confusion about which source is the most current & facilitate reporting on both sides. We want to create a more consistent transparent process flow without burdening you with additional administrative overhead. We're going to transition the following over the coming two weeks into the new tool: active projects, open tasks, key milestones and any relevant documentation. In the meantime, please continue to update your current tracker until you are told otherwise and your workstream has been transitioned. We plan to put out a migration schedule, how-to on logging-in, and a brief little reference guide for the new setup soon. To help with the transition, optional training sessions will be offered as well as office hours — wherein users may come for questions, feedback and troubleshooting. Team leads will additionally evaluate items that have been migrated with their teams to verify priorities, due dates and owners. After all of the above is done, it will become our new single source of truth for project progress and planning. The current trackers will still be available in read-only mode for a limited amount of time before being archived. We appreciate your patience as we work to improve. We welcome questions, concerns or suggestions — please feel free to reach out to me or your team lead during the transition. Best, [Your Name]

Subject: Consolidation of Our Project Trackers to One Tool Dear All, I am glad to inform you that we are going to consolidate our two project trackers into one centralized tool. This will allow us to plan, track, and report project activities in an easier and more coordinated manner. Having a single tracker will help us to clearly see priorities, responsibilities, deadlines, dependencies, and progress. Additionally, this will help to avoid duplicate efforts, prevent confusion on which tracker contains the up-to-date information and will simplify reporting. We will migrate all our active projects, open tasks, milestones, and documentation to a new tool within the next two weeks. You need to keep using your current tracker normally until you get notification that your workstream has been migrated. We will provide you with the migration schedule, instructions and brief manual soon. In order to facilitate migration we will arrange several training and office hours sessions, where you can ask your questions, leave feedback and discuss problems. Also, your team leads will discuss with you your migrated items to ensure that priorities, deadlines and responsibilities are set correctly. After migration our consolidated tool will become the official source of the project status and planning. Existing trackers will stay accessible in read-only mode for some time before being archived. Thank you for your patience and cooperation. Best regards, [Your Name]

Subject: Merging Our Project Trackers into One Tool Hello Team, I’m happy to inform you that we are joining our two current project trackers together into a centralized tool. This alteration aims to make our planning, tracking and communications process easy. One tool will provide a better understanding of our tasks. We will have clear visibility of priorities, owners, timelines, dependencies and progress. Also, we will avoid entering the same information in different places, create less confusion as to which source is valid, and reporting will be easier for everyone. We aim to establish a more consistent and transparent workflow without creating excess work. For the next two weeks, we will have all our active projects, open tasks, key milestones, and documentation moved to a new tool. Please keep on checking in your current tracker until an alert comes to you that your workstream has been transferred to the new tool. We will provide you with a schedule of migration, accessibility information and a short guide for the new tool very soon. To help you get used to the new tool, we will arrange training sessions and office hours for you to ask questions, provide feedback and troubleshoot. Team leads will have to go through the transferred items with their teams to double-check that priorities, due dates and owners are correct. After we are finished, this single tracking tool will serve as the only source of information regarding the projects’ status. It will be possible to view the original trackers in read-only mode for a certain period of time until they are deleted. I would like to thank you for your understanding and assistance in implementing this change. If you have any questions or concerns regarding this process, feel free to contact me or your team lead. Best regards, [Your Name]

Subject: Standardizing Project Tracking We are moving forward with combining our two project trackers into one. With this new system, we expect to improve the way the team plans and maps out project work. This system will also simplify the way the team tracks project work and enhance overall communication. With a unified project management system, the team will be able to track and manage project work more effectively. This will also alleviate the need for team members to update multiple project management systems, which are often out of date. The project management team will transfer all project management documentation and information to the centralized system in the upcoming two weeks. We appreciate your continued support as we transition to this new system. We will provide training and office hours to help with the transition. There will also be opportunities for feedback and to resolve issues that come up. Team leads will also review migrated items with their team members to set and verify project goals and milestones. After the migration, the new and improved project management tool will be the only source of information on project status and planning. We will keep the existing project management trackers for a brief period of time before removing them. We want to thank everyone for their support and patience while we implement this project management system improvement. If you have questions or comments please contact your team lead or us directly.

Subject: Consolidating Our Project Trackers into One Tool Hi Team, I want to let you know that over the next few weeks I will be combining our two project trackers into one, more centralized tool. My hope is that in this way I'll be better able to plan, report on and communicate work across the team. In one tool I could more easily see priorities, ownership, dependencies, timelines and progress on projects. There would be less risk of conflicting updates from different sources, and reporting would be easier for all of us. In the end I would like a more transparent, consistent process across the team, without added administrative burden. Over the next two weeks, I will move projects, tasks, key milestones and supporting documentation from the existing trackers into the new tool. In the meantime, please keep updating your existing tracker. Once I've moved your workstream, I'll let you know. Soon, I'll send out a guide to the new tool, instructions for accessing it and a summary of its features. To help make the move, I'll be holding optional office hours to answer questions, hear feedback and troubleshoot the tool. Team leads will go through items moved from the old tracker with their team to confirm, for example, ownership, due dates and priorities. After the move, this tool will be our main source of project planning and status. For a while, the old trackers will still be available in read-only form. Eventually they will be archived. Thanks for your cooperation in making this improvement. If you have questions, concerns or suggestions about the move, please talk to your team lead or me. Best, [Your Name]

Subject: Consolidating Our Project Trackers into One Tool Hi Team, We will be combining our two current project trackers into a single centralized tool to streamline our approach to planning, tracking and reporting project work to the entire team. Using a single tool will provide greater visibility of priorities, ownership, schedules, interdependencies and progress. It should also reduce duplication of information, minimize confusion about the validity of information sources and simplify the preparation of reports for all staff. Our objective is to achieve a more consistent and transparent system without increasing administrative effort. During the next two weeks, we will transfer all active projects, open tasks, major milestones and relevant documentation to the new system. Continue to update your existing tracker until you receive confirmation that your work stream has been transferred. We will provide a schedule for the migration, instructions for access to the new system and a brief description of the new configuration shortly. To facilitate the transition, we will offer optional sessions on system use and opportunities for discussion of questions, concerns and problems with implementation. Leads for all work units will verify accuracy of priorities, dates of completion and ownership for all items transferred to the new system. After completion of the migration, the single system will represent our official method for reporting the status and planning of projects. Our existing systems will remain available in a read-only mode for a limited period and thereafter will be archived. We appreciate your flexibility and support in making this improvement. Contact us or your work unit lead with any questions, concerns or suggestions related to the transition. Best, [Your Name]

From: Email: To: Subject: Re: Consolidating Our Project Trackers into One Tool Post By: On: Send email to the Group RECURRENT TOPIC. In a previous post, Dhi, you could insert just the setip records as a separate snapwrite-clicks with the corresponding filter, and it would be easy to copy&paste them. It is precisely the easy availability of a single setip with some common fields that can be duplicated and written into a new snapwrite that makes this method convenient. ## Hi Team, I'm happy to announce that we will be combining our two existing project trackers into a single, centralized tracker. We believe this change will make it easier to plan, track, and communicate all of our work. Having just one tracker will help us see priorities, ownership, dates, dependencies and status more easily. It will also reduce duplication of updates, the amount of confusion about the latest source, and hopefully make reporting easier for everyone. We aim to create a more consistent, transparent flow of work without extra admin. Migration is complete? After the following two weeks, we will transfer the live projects, open tasks, important milestones, and documentation. In the new tool. Please keep updating the old tracker until you are notified of the migration of your workstream. We will soon publish a migration timeline, instructions for access and a brief guide to the new platform. In addition, we will provide optional training sessions and hold office hours for questions, feedback, and troubleshooting. Team leads will also review the migrated items with their groups to confirm priorities, deadlines, and owners are correct. After migration, the single tool will serve as the canonical place for tracking, planning and determining project status. The current trackers will remain available in read-only mode for a period of time before being archived. Thanks for your flexibility and support as we make this change. Feel free to contact me or your team lead if you have any questions, issues or feedback while we are in the transition period. ## Best, ## [Your Name]

Subject: Consolidating Our Project Trackers into One Tool Hi Team, I'm happy to share that we'll be consolidating our two project trackers into one tool. This decision was made in an effort to streamline how we plan, track and report on our work, and to improve team communication. Having a single source of truth for our project work will help us prioritize work, understand ownership, deadlines, blockers, progress, and more. The tool will eliminate the need to update two different trackers, and reduce confusion around which tracker to update or which has the most up-to-date information. We want to make the tooling and reporting as simple as possible for you all in your day to day work, while still providing the transparency we need as leaders. We'll be migrating active projects, tasks, milestones, and other relevant information over the next two weeks. In the meantime, please continue to update your active tracker as you normally would until you've heard otherwise. We'll share a migration timeline and instructions for accessing the tool soon, and will host optional training sessions and office hours for any questions, feedback, or concerns. Your team lead will review migrated information with their team to confirm priorities, deadlines, and owners. Once we've completed the migration, the new tool will be our official source of truth for the life-cycle of a project, and the existing trackers will be archived after a brief transition period. Please take care to continue to update your active tracker as you normally would until you've heard otherwise. Thank you for your flexibility and support as we make this change. Best, [Your Name]

Subject: Consolidating Our Project Trackers Hi Everyone, I’m happy to let you know that we’re going to be consolidating our two project trackers into a single tool. We want to make it easier for all of us to plan, track, and discuss our work. By combining the tools, we’ll have a better understanding of what’s important, who’s working on it, when it’s due, what’s blocking it, and how far along we are. I believe we’ll save time from not having to update both trackers and avoid the confusion of which one is up-to-date. I hope we can achieve a standardised and transparent process without adding to the admin. In the next two weeks, we’ll move over active projects, tasks, deadlines, and documentation into the new tool. For now, please keep your tracker up-to-date as normal. You’ll be notified when your workstream has been moved over. A schedule and details on how to access and set up the new tool will follow soon. We’ll have training sessions and drop-in office hours available if anyone would like to ask questions, share thoughts, or get help. Your team leads will check the migrated data with their teams to confirm priorities, due dates, and ownership are correct. When the consolidation is done, we’ll use this tool as our main place for tracking and planning. The other tool will be kept for a limited time for reference, then closed down. Thank you for your patience and cooperation as we make this change. If you have any questions or comments along the way, please contact me or your team lead. Regards, [Your Name]

Subject: Combining Our Project Trackers Hi Team, We're going to merge our two project trackers into one central tool. The idea is to make it simpler for us to plan, keep an eye on, and talk about project work together. Having just one tracker should give us a better picture of what's most important, who's responsible for what, when things are due, how tasks connect, and how we're progressing. It should also cut down on updating the same information in multiple places, stop confusion about which tracker is the most up-to-date, and make reports easier for everyone. We want to set up a smoother, more open way of working without adding extra busywork. For the next two weeks, we'll be moving active projects, ongoing tasks, important deadlines, and related documents into the new tool. Please keep updating your current tracker normally until we confirm your work has been moved. We'll send out a schedule for the moves, how to get access, and a quick guide for the new system soon. To help with this change, we'll have optional training sessions and times where you can ask questions, share feedback, and get help. Team leads will also go over the moved items with their teams to make sure priorities, deadlines, and who's in charge are correct. After we're done moving everything, the single tool will be our main place for project status and planning. The old trackers will still be available to view for a short time before we put them away. Thanks for being adaptable and supportive as we make this change. If you have any questions, worries, or ideas during this time, please talk to me or your team lead. Best, [Your Name]

Subject: Consolidating Our Project Trackers into One Tool Hi Team, We're making a big change to how we manage our projects. Right now, we have two separate tools to track our work, but soon we'll be combining them into one. This will make it easier for everyone on the team to plan, keep an eye on progress, and talk to each other about what's going on with our projects. Having one tracker in place will make it easier for us to see what's important, who's responsible, and when things need to be done. It will also help us avoid doing the same work twice, reduce confusion about what's current, and make it simpler for everyone to report on progress. Our aim is to create a workflow that's consistent and easy to follow, without adding extra admin work that we don't need. This way, we can focus on what really matters and get things done more efficiently. Here's what's going to happen over the next couple of weeks - we're going to be moving all our active projects, tasks that are still open, important milestones, and relevant documents into a new tool. For now, just keep using the current tracker as you normally would until we let you know that your workstream has been transferred. We'll be sharing a schedule for the migration, instructions on how to access the new tool, and a quick guide to get you started with the new setup soon. We're here to help you through this change. To make things easier, we'll be offering some extra training sessions and office hours where you can ask questions, give feedback, and get help with any issues you're having. Our team leads will also be working closely with their teams to double-check that everything is in order, including priorities, deadlines, and who's responsible for what. After we finish moving everything, our new tool will be the main place to go for project updates and planning. We'll still be able to look at the old trackers for a little while, but eventually, they'll be stored away for good. We really appreciate your adaptability and cooperation as we work through this change. If you have any questions or concerns, don't hesitate to touch base with me or your team lead - we're here to listen and help in any way we can. Your input and suggestions are also welcome, so please don't hesitate to share them with us as we navigate this transition together. Best, [Your Name]
