Most small teams keep their to-do list in a chat thread, a shared note, or somebody's head. Tasks get an owner only in conversation, deadlines live in calendar reminders, and nobody can say at a glance what is overdue, what is blocked, and who is carrying too much. The result is a missed deadline that everyone saw coming and nobody flagged.
The Task & Deadline Management System is an Excel workbook that gives a small team one shared task list. Each task has an owner, a priority, a category, a due date, and a status. The workbook compares every due date with an As-of Date you control and flags each task as OVERDUE, DUE SOON, ON TRACK, DONE, or DONE LATE automatically.
A dashboard turns the list into open and overdue counts, a completion rate, workload by team member, and a focus list of the eight most urgent tasks. It is built for the day-to-day work of a team of up to ten people, and it does not need a formal project plan. It works with no macros in modern desktop Excel.
The Dashboard shows five headline numbers: Open Tasks, Overdue Tasks, Completion Rate, tasks due in the next few days (7 by default), and High-Priority Open tasks. Beneath them are a bar chart of tasks by status, a stacked bar chart of open tasks per person split by priority, and a line chart that compares tasks completed each week with tasks overdue at the end of that week.
Next to the trend chart, there is a workload table ranked by open tasks and a priority breakdown. The focus list sits across the bottom and is ideal for a weekly team meeting: it shows the ID, task, owner, priority, due date, flag, and days to due for the eight tasks that need attention first. The Team Summary sheet holds the full tables behind every chart.
The workbook uses standard formulas only and contains no macros, so it opens without security warnings. It is designed for modern desktop Excel on Windows or Mac. Excel Online may display it, but charts and dropdowns are best used in the desktop application.
Does the template need macros?
No. Everything is done with ordinary Excel formulas, conditional formatting, and dropdown lists.
How does it decide a task is overdue?
An open task is overdue when its due date is earlier than the As-of Date in Settings. A task is open until its Status is Done or a Completed date is entered.
Can I use today's date automatically?
Yes. The demo As-of Date is fixed at 20-Sep-2026, so the sample dashboard looks the same every time. Type =TODAY() in that cell to make all flags follow the current date.
How many tasks and people can it hold?
The Task List has room for 300 tasks. You can list up to 10 team members and 10 categories.
What is the focus list?
It is a dashboard table of the eight most urgent open tasks, sorted by due date with priority as the tie-breaker. Open tasks with no due date are not ranked.
Can I change the statuses?
The four statuses are fixed because the formulas depend on them. Owners, categories, and priority names can be edited in Settings.
How do I remove the sample data?
Clear the blue input cells on the Task List and replace the sample team members and categories in Settings. The README lists the exact steps.
