Efficiency is in human nature as we strive to complete our tasks as fast as possible. That's why, if there is a solution that could save us time to do something more meaningful, we will take it.
However, when optimizing their processes, many companies focus only on 3 project dimensions - scope, time, and budget. Productivity and efficiency are often left aside, which can cause problems (or missed opportunities).
3-Dimensional vs. 4-Dimensional Project Management
When it comes to project management, there are many discussions on how processes should be optimized in the best way. As we have already mentioned, most organizations focus on scope, time, and budget. This is known as the three-dimensional approach to project management, which, in my opinion, can be ineffective. Imagine that you have a large project to work on.
- The first thing that you do is to determine the scope of your project.
- After that, you set specific deadlines and milestones that need to be followed.
- At last, you delegate a budget and start assigning tasks.
All of this is great; however, you are not considering your team's efficiency across all these steps. Even if your planning process is perfect, having low productivity and efficiency levels across your team members might lead your project to a catastrophic outcome.
A solution to this problem is embedding team efficiency as a fourth project dimension. Keep reading below to find out how to convert the traditional three-dimensional approach to four-dimensional project management.
Flow Efficiency
In the three-dimensional approach, the scope usually represents a huge task that needs to be broken down into smaller pieces. The idea is to make the individual tasks as small as possible so you can complete them easily one by one. Once this is done, you will know how much time and resources you will need to finish the work.
The fourth project dimension would strive to present your work as a flow. Breaking down a big initiative into projects is not enough if your team's efficiency is low due to an unstable workflow. That's why you need to optimize your team's flow efficiency.
Flow Efficiency[%]=Active Time/Lead Time*100
This can be done by separating the active (value-adding) time from the lead time. The former represents the time during which someone is working towards completing a goal, while the latter is the period between the order and delivery of the product.
Once you combine this with visualizing your workflow through a Kanban board, for example, you will be able to separate the value-adding from the wasteful activities. This will allow you to optimize your work process and deliver high-quality products to the end customer in a predictable manner.
Predictability Instead Estimations
Time is of crucial importance for every single project. That's why it is often being converted into deadlines, milestones, and monthly targets that have to be reached. However, these are often based on rough estimations. Unfortunately, the word estimations often occur in the project management dictionary. And if you allow me, according to the dictionary.cambridge.org, the meaning of the word is:
"Estimation - your opinion of someone or something."
Here is the problem. Estimations are based on someone's opinion. And opinions may be very subjective and elastic.
This can cause project management problems because, in reality, deadlines are often being missed and milestones unachieved. As a result, delayed deliveries occur, which can be catastrophic to any project. And all this because of someone's opinion.
In the four-dimensional project management model, what matters most is the actual data. Data that can help you measure performance and, eventually, team efficiency. The idea here is not to set deadlines blindly but to track how fast your team can produce a specific product. In Lean and Agile management, you can do this by measuring cycle time and lead time.
At the end of the day, both ways will produce results; however, the four-dimensional approach will place a bigger focus on the productivity and efficiency of your team. This way, you will be able to forecast better what time is needed to deliver a product and create superior value for your customers.
Improving Team Efficiency with a Pull Approach
The traditional approach to project management focuses on constantly pushing work into your colleague's hands. This is done so nobody on your team remains idle and is always in top delivery mode.
A push strategy is based on anticipated demand, which can fail to correspond with the actual demand. Even more, while pushing work, you may overburden your team, which creates piles of work. Respectively average cycle time multiplies, and tasks are getting slower.
With the four-dimensional approach, tasks are no longer being pushed. Instead, they are being pulled and distributed by the team members.
A pull system suggests that the team members pull work when there is a free capacity. In other words - a work item has to be in progress only if there is a demand for it and available capacity.
As you may know, in Kanban, capacity is regulated by applying work-in-progress limits that prevent the system from overloading. However, this is a deep topic that will need another 1000 words, so let's proceed.
At the end of the day, Kanban pull systems allow teams to be in charge of their own processes, which will boost their productivity and efficiency. Respectively, team members will no longer execute work only when somebody is supervising them. Instead, they will be responsible for the tasks that they are working on. This also has the power to boost their engagement in the workplace.
Why Team Efficiency?
Team efficiency can help you predict whether products will be successfully delivered to the end customer on time. That's why focusing only on the three project dimensions - scope, time, and budget might turn out to be ineffective. Try the four-dimensional approach to project management and increase levels of productivity and efficiency within your entire organization.
