Why I believe understanding the product lifecycle correctly helps you feel less confused when self-studying product management
When I first started self-studying product management, I kept pondering one question: "When does a product die?" I remember early this year, I bought a phone that had just been released, and I was very excited. As it turned out, after just a few weeks, it froze, the battery drained abnormally fast, and it took two full months before the manufacturer released a patch. I didn't understand how a "brand new" product could be that bad. It wasn't until much later that I learned this is a natural part of the product lifecycle – and that it's not just electronic devices, but everything from software, soft drinks, to cars that go through their own trajectories.
My perspective after a period of self-study: many people are confusing the product lifecycle with the product management lifecycle, leading to wrong expectations at each point in time. The product lifecycle is about how the product itself goes from birth to retirement – while the product management lifecycle is the process that the product team should follow. Grasping the four stages: introduction, growth, maturity, and decline – like having a map – helps you know where you stand and what to do next, instead of panicking the moment a product seems to be "faltering."
Making the distinction from the start: the product lifecycle is not the product management lifecycle
I've read many articles that use these two terms interchangeably, so today I want to clarify this right away. The product lifecycle refers to the stages that the product itself goes through – from the initial idea, being designed, manufactured, brought to market, growing, plateauing, then declining and being discontinued. The product management lifecycle, on the other hand, is the process that the product management team applies to make decisions, plan, and execute throughout that product's life.
Imagine the product lifecycle as a human life: being born, growing up, starting a family, then growing old. The product management lifecycle is like how parents raise a child – caring, teaching, guiding. They are two different things, but they complement each other. If you're self-studying like me, separating these two concepts helps you avoid confusion when reading materials or in interviews – this is also a classic question in product-related discussions.
The introduction stage: a launch can be "imperfect," and that's normal
According to the video I learned from, the introduction stage begins when the product first reaches customers. It includes understanding needs, research and vision development, design, manufacturing, all the way to sales strategy, marketing, supply chain operations – everything needed to bring the product to market. The first buyers at this point are called "early adopters" – they buy early for various reasons: curiosity, wanting to experience it, or genuinely needing that feature.
Interestingly, this stage is often not perfect. Take phones or software for example – I've experienced it myself, and in the lesson they clearly state: electronic and software products often have errors, have bugs, and these get fixed gradually as the product matures. Product managers spend a lot of time "spreading the word" about the product, making it accessible, while also listening to feedback and learning how to improve. In fact, there's a real chance the product fails right here – not every product survives this stage.
Advice for those new to the field: don't panic when you see an early launch version with bugs. Instead of concluding "the product is bad," watch whether the product team is handling bugs quickly and whether they're listening to early users. As a self-learner, you can practice reading blogs after a new product launches – observe what they say about the first feedback loop. That's good practice for understanding the introduction stage.
The growth stage: accelerate but be careful with every step
When a product gets past its early period, it enters the growth stage. Here, product managers ramp up marketing efforts. Even though it's a sign of progress, there's still much to do: marketing strategy may change, production capacity may need to be expanded. The video emphasized that this stage must be executed carefully, because one mistake can negatively affect a product that's already on the market. The goal is to continue growing the product and market share to maintain vitality.
I relate this stage to a runner who's covered the first stretch and now wants to run faster, but if they change their posture suddenly, they can easily get injured. It's completely different from the introduction stage – at that point you're just focused on signaling to people that the product exists; now you need to optimize everything. If you pay attention, software companies often roll out promotions, ramp up advertising, and simultaneously expand servers to handle the surge in users.
Beginners like us should learn to look at growth metrics (revenue, active user numbers, market share) to assess whether the product is heading in the right direction. But also don't forget to observe whether quality is being compromised when scaling too fast – because that's an important lesson from this stage.
The maturity stage: growth plateaus and "slow and steady wins the race"
Most products spend the majority of their time in the maturity stage – growth tends to flatten out. Marketing becomes more sophisticated, starting to introduce nuances and minor product variations. Look at soft drinks: a new flavor from the same brand appears, or cars that change only slightly each year – adding some aerodynamic technology, a new safety feature – but rarely undergoing complete transformation.
I find this extremely interesting because it reflects real life: at some point, the boom gives way to stability. If you've ever seen a product that's "no longer as hot" as before but still sells steadily, that's the maturity stage. Companies try to optimize profits from the product, cut production costs, and polish small upgrade versions.
For those self-studying, I recommend picking a familiar product (such as a soft drink or a car model) and tracking its history. You'll see that the maturity stage can last many years – and recognizing it helps you not feel confused when the product is no longer "growing at lightning speed" like at first. One point worth considering (a light counter-argument): some people think maturity is a sign the product has "no room left," but in reality this is the stage that yields the most profit thanks to low marketing costs and a loyal customer base.
The decline stage: not an ending, but an opportunity for the next product
When the customer market shifts, the product begins to decline and eventually ends its lifecycle. Product managers at this point must focus on strategy for developing the next product. The classic example is CDs and DVDs – they were gradually phased out as streaming services became popular. I remember when I was young, every household had a shelf of music discs; now you just open Spotify or Netflix.
Decline isn't scary. It's like a piece in the bigger picture: old products leave to make way for new products
