North Star Metrics: guiding your business to stellar results

For centuries, people knew that you would never be lost if you could find the North Star in the sky. Polaris, our current North Star, is clearly visible to the naked eye at night and has a stable position in the sky, making it indispensable for navigation. No wonder its name was given to the metric companies use as the key indicator of long-term success. Choosing a north star metric (NSM) is a way to measure company growth and success using only one overarching metric. North Star metrics are used in multiple companies to measure company progress and help everyone focus on the same goal, thus enhancing communication and collaboration across all teams.

Reliability engineering — its significance and key principles

Choosing a product or a service to buy is a complex process. Your own tastes play an important role, of course, but very often product reliability is what impacts your decision most of all. It is especially important when you are looking at something that can potentially serve you for many years to come. Nobody likes spending a ton of money on a device that works right now but will fail in a couple of months. However, we can all agree that nothing lasts forever. Any product or system can fail, which is why warranties exist.

Best practices for a successful and secure software development life cycle (SDLC)

It’s not a secret that reaching any goal is easier when you have a clearly outlined plan. Knowing what exactly you are going to do and in what order gets you at least halfway on the road to success. This is especially true when it comes to such a complicated and multifaceted process as software development. If you strive to implement a workflow that is well-structured, iterative, and systematic, your web or mobile application development process becomes more efficient, transparent, and cost-effective.

Prototype vs. Final Product: key differences and similarities

Prototypes and final products hold distinct roles in the development process. In this article, we will delve into their differences, similarities, the dynamics between them, and the importance of incorporating a prototyping phase in your product’s development. Please keep in mind this article focuses on a product-centered approach. Prototype has a different meaning for backend development. Let’s start by understanding the concepts:A prototype is a preliminary version or early model of a product. In software development, a prototype is a digital simulation of an application or system, created to test the functionality, user experience, and to validate the design and interface.

The importance of a secure software development life cycle (SSDLC)

In today’s world, where technology plays an important role in many aspects of our daily lives, the software we use must be both innovative and secure. Unfortunately, many companies still view security as an obstacle in the development process. However, insecure software poses a significant risk to businesses. Even the most innovative feature will not bring much value to the product or its user if it's vulnerable to hacking. The solution to this problem is adopting a secure software development life cycle (SSDLC), a comprehensive approach to software development that puts security first in the process.

A definitive guide to proof of concept vs. prototype in product development

Software development is one of the most competitive industries these days. Even if we look only at the applications, the numbers are staggering. There are tens of thousands of new apps released every month, and obviously, only a handful of them become successful. No matter how original the app concept might seem, a lot of considerations need to be taken into account before making the final decision to turn the concept into a working app. Both a proof of concept and a prototype are often mentioned among the most popular methods that help to determine if a product idea is viable and worth pursuing.

From idea to reality: the meaning of PoC in software development

Being optimistic about gaining support for an idea or project is not enough. Investors and stakeholders are typically pragmatic and require concrete evidence that business proposals can be viable and successful. This is where a proof of concept (PoC) comes in. A PoC demonstrates the core functionality or a key component of the planned software to demonstrate that it's feasible and likely to meet business goals. We’ve already thoroughly covered what a PoC is in one of our articles, but here we want to give a quick reminder.

Understanding the Differences Between Proof of Concept vs. MVP

Once you have an idea for a product, you need to validate it. Proof of concept and MVP are well known ways to do that. They help you assess how you can develop the product, how it can be improved and whether it’s even worth your time and resources. However, MVPs and PoCs serve different purposes and are used in differing circumstances. Read the article to learn what they are exactly, the difference between them and when to use each of them. A proof of concept, or a PoC, is a way of validating a product’s feasibility.

What is cloud-native architecture — everything you need to know

Gone are the days when most IT companies had their own physical data centers. On-premises infrastructure is no longer a prerequisite for running a successful IT business. Cloud data storage and hosting has become so routine you barely even give it a thought. More often than not, customers expect your app to be hosted in the cloud because they associate it with less downtime, speedy work and reliability. However, when considering cloud infrastructure, there is a big difference between cloud-native and cloud-enabled applications.

The Seven Stages of the SDLC

The software development life cycle (SDLC) is a process for building and delivering software – each of its phases helps with planning, building, testing, and maintaining an application. Implementing the SDLC can ensure high quality, better-functioning software. What’s more, the SDLC optimizes strategy by dividing the main business goal into smaller, easier to achieve units. However, it is hard to implement the software development life cycle wisely and adequately without a good understanding of its phases.

Software development roadmap — what do you need to know?

How can you properly develop software without a plan? Probably, no entrepreneur has an answer for that question. Why? Because there is none. Every product needs a defined strategy, key priorities, workflow, clear responsibilities and division of tasks. A software development roadmap brings all these together in one place. Let’s look at what a software roadmap is, the different roadmap types, how it can benefit the project, and how to create a successful roadmap. A software roadmap helps to provide a high-level plan and overview of the software development progress and the product's goals.

How long (for real) does it take to make an application?

If you're planning on building an app, you want to know how long the process will take. And that is entirely understandable—you have to coordinate the development process with many other aspects, such as marketing and advertising campaigns, product introduction to the market, predicting what upcoming trends or regulations could impact your business, etc. However, there is no single answer to the question, "How long does it take to make the app?". Oh, sorry, there is one- "it depends." That’s not very satisfying but it's the reality—do not believe any article that gives you a specific answer.
