Timesheets are like TPS reports* of any project. Team members think of them as an annoying activity. For managers, timesheets are a vital component to understand how team is working and where the effort is going. I will not get in to the merits and pitfalls of timesheets. However, I feel that by using Microsoft Excel capabilities you can create a truly remarkable timesheet tracking tool and still leave your team members un-annoyed.
In this tutorial we will learn 3 things about timesheets and resource management using Excel
- How to setup a simple timesheet template in excel?
- How to make a more robust timesheet tracker tool in Excel?
- How to use the timesheet data to make a resource loading chart?
1. Make a Simple Excel Time Sheet Template
According to Wikipedia, timesheets are used for
Timesheets may record the start and end time of tasks, or just the duration. It may contain a detailed breakdown of tasks accomplished throughout the project or program. This information may be used for payroll, client billing, and increasingly for project costing, estimation, tracking and management.
By defining a simple and straight forward template in Excel and using it to track time (or efforts) in your projects, you can easily consolidate the data, compare efforts and make any necessary analysis.
At its simplest form, the timesheet is nothing but list of team members and list of activities in a matrix. Look at the below example:
You can easily create such template in excel.
2. A More Robust Excel Timesheet Tracker
While the time sheet format shown in the above section is good, it is a wrong format if you need to analyze the timesheet entries of a 100 member project. Also in large projects usually members do few activities at a time. That means the above format (in section 1) will result in a sparse matrix.
Using a tracker log format is much more convenient to both record and analyze timesheet entries. Look at the example below:
We can use excel features like data validation drop downs, shared workbooks to make the timesheet entry and management a breeze.
3. Create a Resource Loading Chart – Project Management
Resource loading charts are a good way to show how busy the team members are in a project. At the outset the resource loading chart is nothing but a heatmap.
Look at an example resource loading chart below:
You can make a resource loading chart in MS Excel by following the below steps:
- The pre-condition for the resource loading chart is that we have clear data available to make one. This is where the robust timesheet tracker shown in section 2 of this post comes handy.
- First create a blank table in excel with team member names in first column and week numbers in first row. (Please note, you can make other types of resource loading charts by changing the Row and Column headers. For eg. You can show resource loading by Project and Team member)
- Assuming we have the time sheet data in the format shown in Section 2,
- Assuming “log_member_names” refers to the member name column and log_weeknum refers to the last column in the timesheet, we can write a simple SUMPRODUCT formula like this:
=SUMPRODUCT(--(log_member_names="John Galt"),--(log_weeknums="3"))to calculate the count of activities John Galt has done on week 3. Learn more about using SUM and SUMPRODUCT to calculate sumif with multiple conditions.
- Once we calculate values for all team members using the above formula, we can apply conditional formatting to make the heat map. In Excel 2007, this is one step. In earlier versions of excel, you need to specify 3 conditions to make the heatmap look hot enough or use a macro to get over the 3 conditional formats limitation.
- That is all.

Timesheets are a great way to understand how the effort is spent. Even though project estimation models have become more and more effective, still lots of projects are overshooting budgets and timelines. And this is where timesheets can help you as a manager. While estimation looks in to future, timesheets look at past. Timesheets give feedback to your estimation models. This can help you in making better estimates in future.
In the next installment of this series, learn about tracking issues and risks using excel spreadsheets.
