Feed Forward: Unlocking Future-Oriented Growth And Control Theory
The term "feed forward" occupies two distinct yet critical domains: the professional development and leadership methodology focused on future-oriented improvement, and the engineering discipline within control theory. While one seeks to optimize human performance and organizational culture, the other ensures stability and precision in complex mechanical or electronic systems. Both, however, share a core philosophy: anticipating future states rather than merely reacting to past errors.
Feed Forward in Leadership and Professional Development
In the context of management and personal growth, Marshall Goldsmith popularized "feed forward" as an alternative to the traditional feedback loop. Feedback is inherently historical; it examines what has already happened, often triggering defensiveness because it focuses on past mistakes or shortcomings. Feed forward, conversely, shifts the focus entirely to the future. It is a proactive approach where individuals ask for suggestions on how to achieve a specific goal rather than asking for a critique of past behavior.
The power of this technique lies in its ability to bypass the ego. When you ask a colleague, "What are two things I can do to be a better communicator in our next project meeting?" you are not inviting them to judge your previous lackluster performance. You are inviting them to partner with you in your future success. This simple shift in framing changes the power dynamic of the conversation, fostering a collaborative environment where growth is continuous and forward-looking.
Implementing this strategy requires specific conditions to be effective. First, the goal must be clear and tangible. Vague requests like "how can I be better?" lead to vague answers. Second, there must be a genuine openness to listen. Because feed forward is future-oriented, it requires the recipient to act on the suggestions provided. By ignoring the advice given during a feed forward session, trust is eroded, and future contributors will be less likely to offer their insights.
Engineering and Control Theory: The Feed Forward Mechanism
In engineering and system dynamics, a feed forward controller is a control system that uses measurements of process disturbances to adjust the control input before those disturbances impact the system's output. Unlike feedback control, which waits for an error to exist before making a correction, a feed forward system anticipates the impact of external variables. By the time a feedback loop realizes an error has occurred, the system has already deviated from its setpoint. Feed forward prevents that deviation entirely.
To design an effective feed forward controller, you must possess an accurate model of the process. You need to understand exactly how a change in the disturbance variable (e.g., incoming temperature of a fluid) affects the output (e.g., outgoing temperature). If the model is imprecise, the feed forward action might actually inject noise or instability into the system rather than smoothing it out. This is why feed forward is rarely used alone; it is almost always paired with a feedback loop to handle the inevitable inaccuracies in the model.
Consider an industrial HVAC system. If the system only used feedback, it would turn on the heat only after the room temperature dropped below the setpoint. A feed forward controller, however, can monitor the outdoor ambient temperature or the number of people entering the room. As soon as the system senses an increase in occupancy or a drop in outdoor temperature, it adjusts the heating output before the room's internal temperature actually drops. This results in far tighter control and higher energy efficiency.
Comparison: Feedback vs. Feed Forward Control
| Feature | Feedback Control | Feed Forward Control |
|---|---|---|
| Response Timing | Reactive (after error occurs) | Proactive (anticipates error) |
| Data Requirement | Measures output deviation | Measures input disturbances |
| Stability | Inherently stable if tuned well | Potential for instability if model is wrong |
| Complexity | Simple, works with black boxes | Requires detailed system model |
| Error Correction | Corrects all errors (modeled or not) | Only corrects modeled disturbances |

Pros and Cons of Feed Forward Strategies
Whether in a business office or an automated factory, the "feed forward" concept offers distinct advantages, but it is not a universal panacea. Understanding the trade-offs is essential for implementation.
The primary advantage is speed. Because you are addressing potential issues or growth opportunities before they manifest as failures or errors, you maintain a higher level of performance efficiency. In leadership, this means building stronger team alignment because members feel their potential is being nurtured rather than their past being audited. In engineering, it means achieving a setpoint that is virtually identical to the target, significantly reducing the "settling time" of the process.
However, the downsides are significant. In the human context, feed forward can sometimes be used to ignore past systemic issues that need addressing. If an individual has a recurring behavioral problem, focusing only on the future might prevent them from taking responsibility for past harms. In engineering, the dependency on a system model is a major weakness. If the environment changes in a way that wasn't modeled—a phenomenon known as model mismatch—the feed forward controller will make the wrong adjustments, potentially causing the system to crash or fluctuate wildly.
How to Get Started with Professional Feed Forward
If you are a manager or professional looking to pivot from traditional feedback to feed forward, the process is straightforward but requires discipline. Start by identifying one specific area of your professional life you wish to improve, such as public speaking, email responsiveness, or strategic delegation.
- Define the Goal: Clearly state the goal in the future tense. "I want to improve my project delivery timelines by 10% in the next quarter."
- Select the Right Partner: Choose someone who is knowledgeable about your work but not necessarily your supervisor. Peers often provide the most constructive forward-looking advice.
- The Request: Ask: "What are two things I could do in the next quarter to help reach my goal of faster project delivery?"
- Listen and Record: Do not defend, debate, or explain. Simply listen, take notes, and thank them.
- Execute: Pick the advice that resonates most and implement it immediately. Following through is the most important step; it signals that you respect the input and are serious about your development.
Frequently Asked Questions
1. Is feed forward a replacement for feedback? No, it is a complement. Feedback is necessary for performance reviews and addressing past behaviors, while feed forward is for professional development and future-oriented problem solving.
2. Why do control systems use feed forward and feedback together? Feed forward handles the "predictable" disturbances, while feedback handles the "unpredictable" errors or modeling errors, ensuring the system remains stable regardless of external conditions.
3. Does feed forward work in every leadership situation? It is most effective when there is trust. If there is a high degree of conflict, feed forward can feel dismissive of past issues, so use it carefully in toxic environments.
4. What is the biggest risk of using feed forward in engineering? The biggest risk is model error. If the controller anticipates a disturbance that doesn't occur, or underestimates its impact, it will push the system away from the setpoint.
5. Can I use feed forward with a large team? Yes, it is excellent for team meetings. By asking for "feed forward" on a future project phase, you empower the team to anticipate risks before they occur, rather than conducting a post-mortem after a failure.
Take charge of your trajectory today. Whether you are optimizing a PID loop in a complex industrial process or seeking to become a more effective leader, adopt a forward-looking mindset. Start by identifying one variable in your current system—be it a team process or a machine setpoint—and ask: "What can I change now to ensure the future output is exactly what I need?" Begin your transition to proactive optimization today.
