SaaS Development Lifecycle: Understanding Stages and Steps

Imagine living in a time before Slack or Gmail. How tedious and difficult it would be for organizations to handle any communication.

Either they would spend a lot of time, effort, and resources building their own communication tool, or spend hundreds of thousands of dollars just on purchasing communication software for every employee. Thank goodness we live in a time like this. A time when we can simply subscribe to cloud software as a service and access it over the Internet.

If you also want to reap some benefits from this rapidly growing industry, here's how to get started with SaaS application development. But before diving into the SaaS application development lifecycle, let's talk a bit about SaaS products.

What is a SaaS Product?

Before moving on to the SaaS development lifecycle, it's essential to understand what software as a service is and how it differs from a traditional software product.

SaaS (Software-as-a-Service) is a software licensing model where access to software is provided on a subscription basis, and the software is hosted on external servers rather than on servers located within the company.

SaaS Development Lifecycle

This type of application represents a cloud model where all maintenance, updates, security analysis, etc., are handled by the vendor or owners of the SaaS product. Users of the SaaS product pay a monthly, annual, or other periodic subscription fee for using the software services.

Typically, SaaS products are accessed via web browsers. The provider hosts the SaaS products either on their own servers, computing resources, databases, or in the cloud of a third-party internet provider. Since they are usually hosted in the cloud, users can access them over the Internet using mobile devices or web browsers. No physical media or user installation is required to use SaaS products.

Stages of the SaaS Development Lifecycle

Building a SaaS product goes through various stages. Similar to the traditional software development process (SDLC), the SaaS development lifecycle also consists of specific stages. We have divided them into three: the Planning Stage, the Selection/Subscription Stage, and the Development Stage.

Planning Stage

This type of application represents a cloud model where all maintenance, updates, security analysis, etc., are performed by the vendor or owners of the SaaS product. Users of the SaaS product pay a monthly, annual, or other periodic subscription fee for using the software services.

#1. Planning

The first step in the planning stage is creating a product concept. You have a product idea, but you need to present it. At this stage, you are simply exploring possibilities. It's similar to creating any other product. You need to define the scope of your SaaS software product. The scope of your project, business prospects, target market, and other things should also be mentioned in this step.

#2. Research

Whether you are building simple software or developing a SaaS product, research is one of the most important stages. You need to not only research the product idea but also conduct basic research regarding target customers, competitors, and the market. You need to know your target market and customers inside out to identify commonalities for creating SaaS product features.

#3. Evaluation

After creating a SaaS product, it is crucial to evaluate the SaaS product idea before proceeding. The most important aspect of evaluation is analyzing various cloud providers. You need to analyze and evaluate all aspects of the product idea and make critical decisions that will affect the SaaS product after implementation.

#4. Requirements Definition

The next important step is defining the requirements for the SaaS product. You need to define the requirements for the SaaS product in terms of multi-tenant architecture, self-service, security, and monitoring of user actions.

Selection/Subscription Stage

After you have conceptualized, researched, and evaluated the SaaS product idea, it's time to move to the selection or subscription stage. This is where the most important decisions in the SaaS development lifecycle are made.

#1. Choosing a Cloud Provider

The first choice you need to make is selecting a cloud provider. This will be a huge part of your SaaS product. It will determine which cloud provider will host your SaaS product. You need to evaluate openness, scalability, availability, economic feasibility, support capabilities, and other aspects of the cloud. You need to assess the capabilities of the cloud provider's platform as well as the architectural changes they offer.

When choosing a cloud provider, consider the following points:

Develop the technical architecture of your SaaS product
Define testing points
Analyze cloud platforms according to the technical architecture
Shortlist platform providers
Finalize the platform and proceed with implementation and design.

There are various reliable cloud providers such as Amazon AWS, Google Cloud, Microsoft Azure, and others from which you can choose the right one.

#2. Choosing a Development Methodology

The next important thing to choose is the development methodology. There are various methodologies you can choose for the SaaS development lifecycle. Before starting SaaS development, you need to select a methodology that will set the pace of development. Among the popular development methodologies are the following:

Agile: One of the most popular methodologies is the Agile software development methodology. It allows iterations, changes, and improvements. Development is done in sprints. Great for working with remote teams or developers. You can also iterate your product based on SaaS trends if they change.

Waterfall: This is one of the most sequential methodologies. However, moving to the next stage is not possible until the previous one is tested and completed.
Scrum: An Agile software development approach that focuses more on sprint latency and retrospectives.
Spiral: This is a development cycle where each phase of development is like a loop, and an evaluation of one stage influences the next cycle.

#3. Choosing a Technology Stack

The next and very important choice for the SaaS development lifecycle is selecting the technology stack. The choice of technology stack affects the development environment experience. It also ensures how optimal the SaaS software ecosystem will be.

There are several SaaS frameworks, and you need to choose front-end technology, back-end technology, database, and even new-age technology that you want to integrate into your software. This could be AI, blockchain, machine learning, IoT, or any other emerging technology to bring digital innovation to your product.

#4. Choosing a Delivery and Pricing Model

The next important choice for your product is selecting the delivery model as well as SaaS pricing. You need to decide what type of subscription you want to offer or what delivery model you want to create with your SaaS product. Thus, you need to choose a subscription-based pricing model to offer to your customers. Common subscription models include the following:

Freemium Pricing Model: One of the most popular SaaS subscription models is the Freemium or ad-supported model. It provides customers with free usage for a limited time and then asks them to purchase the paid version. This is a great way to attract more paid subscribers.
Flat Fee Model: This is another model where the SaaS product provider charges the same fee to all users, regardless of how many users they use or want to add.
Tiered Model: This is a subscription model that provides flexibility in offering products. It is a common model that allows customers to upgrade their tier and unlock new features as they start seeing benefits. SaaS product owners should offer clear advantages in such a scenario to upsell to existing customers.
Usage-Based Model: This is a common model where the customer pays based on actual usage of services. This provides the customization and transparency many customers need.
Per-User Model: Another popular SaaS delivery subscription model could be the per-user model. Customers can request a price based on the number of users they target. This model is particularly convenient for those offering a SaaS product for internal functions.
Feature-Based Model: This is a great SaaS subscription delivery model for all those whose SaaS software is packed with countless impressive features. It is somewhat similar to the tiered model and offers pricing based on the features customers need.

These are some of the popular subscription models offered by leading SaaS companies. You can evaluate your product, planned features, number of allowed users, etc., to determine the subscription model. Many companies also create a hybrid of different models to offer more flexible customization.

#5. Choosing a Monetization Strategy

Every business aims to monetize its product idea. Determining the revenue strategy before development begins can ease the entire process. You need to know if the revenue will come from subscriptions, advertising, or the Freemium model. If you are creating a marketplace, you could even add a transaction-based fee system.

Development Stage

One of the most critical and time-consuming stages of the SaaS development lifecycle is the development stage. At this stage, you need to create a development environment and start working on the SaaS product, starting small.

Here are the main steps of the development process.

#1. Building a Development Team

SaaS application development requires many months and a dedicated team of specialists. Therefore, the first step in creating any SaaS product is assembling a software-as-a-service development team. An ideal SaaS development team should consist of a project manager, business analyst, UI/UX designer, backend developer, frontend developer, QA engineer, product manager, and others. To create a SaaS product, you can either build your own team or hire remote developers from an agency. You can even set up a dedicated team for SaaS application development. Another cost-effective and time-efficient solution for building a SaaS application is to outsource it to experts.

#2. Creating an MVP

Once the team is ready, the first step in the SaaS development lifecycle is to create a Minimum Viable Product (MVP). At this stage, the first version of the product is created. This is the first step in development. It will help evaluate the idea, test it with people, gather feedback, and analyze the business monetization strategy. It also helps save money if your SaaS idea doesn't pan out. Developing an MVP also saves on costs.

#3. Testing on Early Adopters

After the MVP is developed, the next step is testing the prototype. You need to launch the product with beta testers or early adopters. You need to get feedback from them and make adjustments accordingly.

#4. Iteration and Launch

After collecting feedback, you can move to the next sprint and refine the product based on the feedback received. You can add new features, improve the experience, and create a more polished version of the product. You use your chosen work methodologies, tool sets, technology stack, and more. You can also integrate APIs into your SaaS product to expand its capabilities and even optimize it before launch.

#5. Management, Monitoring, and Optimization

After deploying, launching, and testing the SaaS application, you need to move to management, monitoring, and optimization of the product. This means the SaaS product must be fully updated and maintained. You also need to continuously monitor the software to ensure it has everything needed for flawless operation. You need to manage servers, databases, and other aspects to ensure accurate operation for the user base.

These are the steps you need to take during the development stage of the SaaS product. After the product goes live, you must continue scaling it. This includes adding new features, monitoring, integrating APIs to improve the product, and more.

In Conclusion

Creating a SaaS product is certainly a great business move if you have an excellent idea and want to capitalize on a rapidly growing industry. But as mentioned above, the process can be quite complex with many stages and steps.
