Quality, Speed or Price: The Unattainable Triangle
May 5, 2015
The triangle is considered to be “unattainable” because any business that attains it would be inherently flawed. For example, in an ideal world, businesses would produce high-quality goods at a fraction of the cost and time. Logistically, this theory doesn’t work. Think about what happens in the business world. Consumers associate high prices with high quality and cheap prices with low quality rather that is true or not.
Relying on sales volumes to sell products at a lower price point doesn’t work as efficiently as we would think. The notion of “too good to be true” plays a big role in the problem. To put this dilemma into perspective, imagine if BMW started selling their $50,000 cars for only $20,000. Wouldn’t you assume that there was something wrong with the car? Where did they start cutting corners? As consumers, we are trained to associate the price point with quality and speed. You get what you pay for, therefore, you must pick two of the three (quality, speed, price). What is more important to you? If you are a business owner, your involvement in the triangle will depend on your values. The triangle allows business to take a step back and analyze their goals, their process and what your audience is looking for. If your audience is looking for a quality item and your goal is to create a quality item then all is well. But, if your audience is looking for a mid quality item with a fast turnaround and low prices and you have to ask yourself if it’s worth investing in this mindset and losing sight of your original goals and values. The unattainable triangle is unattainable for a reason. Trying to implement all three is points of the triangle is bad business. If you’ve got an amazing product, why would you want to under sell it? Or if you’re able to deliver a fast turn around, why charge the same amount as competitors who are twice as slow? Customers are trained to associated price with quality and that is the main reason why the unattainable triangle may always be unattainable.
Understanding the Unattainable Triangle
The unattainable triangle (also known as the quality speed cost triangle or speed price quality model) is a long-standing concept in project management and business strategy. It states that when delivering a product or service, you can only reliably optimize for two out of three factors: speed, cost, and quality.
This triangle exists because each point directly affects the others. Faster delivery requires more resources. Lower prices reduce the ability to invest time and expertise. Higher quality products demand careful planning, skilled labor, and realistic timelines. The triangle isn’t about limitation, it’s about transparency. Understanding it allows businesses to set realistic expectations and make intentional trade-offs instead of reactive compromises.
Communication and Service Quality
Clear communication is essential when quality is a top priority. Businesses that deliver quality work consistently often have a strong track record built on setting expectations early and sticking to them. That means being honest about timelines, scope, and what it takes to produce work at the same level every time.
When service providers communicate openly, clients understand why higher quality products take longer or cost more. This clarity builds trust and reinforces the idea that quality isn’t accidental, it’s the result of experience, planning, and care. Without strong communication, even excellent work can feel frustrating or misaligned.
Communication and Delivery Speed
Speed without communication leads to confusion. When fast turnaround is the priority, proactive communication becomes even more important. Teams must clearly define what “fast” means, what corners won’t be cut, and what trade-offs may occur.
Think of something like a postal service: expedited delivery costs more because it requires prioritization and resources. The same logic applies to project management. If a client needs something quickly, communicating the implications (whether that’s higher cost or reduced scope) helps prevent disappointment and protects the quality of the final result.
Communication and Cost Efficiency
Cost efficiency is often the most misunderstood point of the unattainable triangle. Many assume lower cost should still deliver the same level of quality and speed, but that’s rarely realistic. Communication helps reframe cost as a strategic choice rather than a compromise.
When budgets are tight, teams need to discuss what can be adjusted (scope, timeline, or execution level) without sacrificing the integrity of the work. Transparent conversations ensure everyone understands what’s achievable and avoids the trap of expecting premium results at bargain pricing.
Frequently Asked Questions (FAQs)
What is the unattainable triangle in project management?
The unattainable triangle in project management refers to the balance between speed, cost, and quality. It suggests that a project can only optimize two of these factors at a time. Attempting to maximize all three usually leads to burnout, poor quality work, or missed expectations.
How does the quality-speed-cost triangle impact businesses?
The quality speed cost triangle forces businesses to define their values and positioning. Companies known for higher quality products often accept longer timelines or higher prices, while others compete on speed or affordability. Understanding this model helps businesses make strategic decisions rather than reactive ones.
Why can’t projects achieve speed, price, and quality together?
Because each factor pulls resources in different directions. Speed requires focus and manpower, low price limits resources, and quality demands time and expertise. Trying to achieve all three usually results in cutting corners, reducing quality, or overextending teams.
Which factor should you prioritize in the unattainable triangle?
That depends on your goals, audience, and values. Some businesses prioritize quality to protect their reputation and track record. Others prioritize speed to stay competitive. The key is choosing intentionally and communicating that choice clearly to clients and stakeholders.
Can technology reduce trade-offs in the speed-price-quality model?
Technology can improve efficiency, but it doesn’t eliminate trade-offs. Tools can streamline workflows and support project management, but they can’t replace human judgment, experience, or craftsmanship. Even with technology, the core principle of the unattainable triangle still applies.
