Can you afford to ignore a technology innovation that will likely deliver an economic output worth $13 trillion by 2030?
If you are an entrepreneur or a senior leader in an enterprise or government/non-governmental organization, then you can‘t! As I have previously explained in “10 best AI apps of 2019”, AI has a wide range of applications.
According to a McKinsey report titled “Notes from the AI frontier: modeling the impact of AI on the world economy”, AI will not only create economic value worth $13 trillion by 2030, but it will also boost global GDP by 1.2% a year.
No matter what your business or organizational function is, AI probably has one or more vital use cases that will help to transform your company!
That said, you still need to implement an AI solution into your organization, and this requires you to know the AI development life cycle. In this guide, I will explain exactly what this is and how it works.
The relevance of AI
Artificial Intelligence (AI) is an interdisciplinary branch of computer science, which saw decades of research and development before it was commercialized as a technology. This technology focuses on making computer systems perform tasks that would normally require a human being.
AI involves “training” computer systems on tasks using “experience”, and the “experience” is obtained from a massive amount of data. As more data is fed to the computer system, it “learns” more and performs the task better. Read “Artificial intelligence | what is it and why it matters” for more insights.
AI has use cases in several sectors like agriculture, banking, healthcare, manufacturing, retail, etc., moreover, it can transform various functions like customer service, fraud prevention, etc. Not surprisingly, the global market of AI is growing significantly. Your organization could benefit from AI too!
This market will likely reach $190.61 billion by 2025. A MarketsandMarkets research report states that the global AI market will have a CAGR of 36.62% during the 2018-2025 period.
An overview of the AI development life cycle
Developing an AI solution is a software development project, therefore, there are fundamental similarities with other such projects. However, there are a few unique flavors to an AI development project.

The life cycle of an AI development project is as follows:
1. Define why you would use AI
There are many exciting technology innovations, however, your business/organization has its core functions to discharge, and not just jump into every technology bandwagon! While AI has transformative potential, you need to know why you would use it.
Having clarity on this is the very first step. You can‘t achieve this clarity by just imposing AI in a top-down manner from the beginning. In every business or organization, the people who serve the customers are in the frontline, and they have the first-hand view of where the organization needs to transform.
While the high-level decision-making of where to use AI rests with the senior leaders in an organization, the input for this must come from the people that serve the customers. This will make the application of AI in your business meaningful, and you can read about this in “How to make an AI project more likely to succeed”. You need to have a project manager (PM) available full-time during this stage.
2. Choose what you will automate
A clarification first! AI isn‘t automation as we traditionally understand it, and in fact, AI is very different from rule-based automation. Rule-based automation involves programming the automation of a task, based on a set of rules. On the other hand, AI involves computer systems learning from experience, and performing the task better in an automated manner.
Notwithstanding the difference between the two, you are likely considering AI to automate parts of your business processes or organizational functionalities. You want to realize greater value than what rule-based automation can provide, and that‘s why you are planning to implement AI.
What do you automate though? This is a key question since your objective is to unlock greater opportunities or to improve your organizational efficiency. Your people are still very valuable, and you want them to work on the real value-added stuff.
This calls for a careful identification of tasks you will automate with AI, thus enabling your skilled personnel to work on what shouldn‘t be automated. Read “Artificial intelligence and robotic process automation” to learn more about using AI in automation. You need the PM and an IT architect in your team at this stage.
3. Carefully select the data sets for your proposed AI solution
AI needs data. That‘s a given, however, which data should you use to train your AI system? This question is very important since the appropriate selection of data sets is what will give you the best value from your AI solution.
Should you feed as much data to your AI or ML algorithms as you can? Well, that might sound attractive since the algorithms have more data to “learn” from. However, in practice, that‘s not always the correct approach!
Most businesses don‘t have clarity about much of their data, and in such cases, feeding data to the AI/ML algorithms will not deliver optimal value. You need to use “Data Science Hierarchy of Needs”, created by Monica Rogati, an equity partner at Data Collective. Read about it in “The AI hierarchy of needs”.
In this hierarchy, the first level is to collect data from relevant sources. The organization needs to store this data securely, subsequently, it needs to explore and transform it. They need to then aggregate and label it, followed by optimization.
The organization should then feed the resultant data sets to the AI/ML algorithms. This ensures that your proposed AI system has the right data to “learn” from, and you can read more about it in “Data is the foundation for artificial intelligence and machine learning”. You need data modeling experts along with the PM and architect at this stage.
4. Identify the AI capabilities you need
AI isn‘t monolithic. The tremendous value that AI creates comes from various AI capabilities, and your proposed AI solution might need several of them. You need to study the following AI capabilities and choose the ones you need:
- Machine Learning (ML): This includes deep learning, supervised algorithms, and unsupervised algorithms.
- Natural Language Processing (NLP): This encompasses content extraction, classification, machine translation, answering questions, and text generation.
- Expert systems is another key capability.
- Vision: This includes image recognition and machine vision.
- Speech: Speech-to-text and text-to-speech are included in this capability.
Planning and robotics are other key AI capabilities, and you can read about these in “Artificial intelligence: definition, types, examples, technologies”. At this point, your team should consist of the PM, the architect, data modeling experts, and an AI/ML solution architect.

You should also create a Rough Order of Magnitude (ROM) estimate for the project so that you can get the necessary approvals from the project sponsor. Read more about ROM estimate in “The Rough Order of Magnitude Estimate”.
5. Agree on the right SDLC model for the project
A software development project to develop an AI solution is a strategic one since it addresses high-value objectives. Finalizing the requirements upfront is important here since scope creeps later in the cycle are costly.
The Waterfall SDLC model is the right one for such projects. It stresses on carefully baselining the requirements before the design starts, moreover, this model facilitates timely reviews of the project after key phases. Read more about the Waterfall model in “What is software development life cycle and what you plan for?”.
This model has the following phases:
- Requirements analysis;
6. Requirements analysis
You need to onboard business analysts in your team at this point so that the requirements analysis phase can start. While you ought to follow the industry-standard requirements analysis processes, there are a few best practices for AI development projects.
Business analysis should consider the following factors while analyzing the requirements for an AI solution:
- Customer empathy;
- The AI solution should be consisting of smaller components;
- Avoiding bias arising from wrong data.
Read “4 tips for writing artificial intelligence requirements” to learn more about this.
The PM and architects should prepare a budget estimate at this point. You can read our guide “How much does it cost to develop an AI solution for your company?” and gain insights on how to do this.
The next step in the AI development lifecycle is the design phase, and you now need the AI development lead. Assuming you are planning to launch the app on the web, Android, and iOS, you need the corresponding development leads. The test lead and the DevOps lead need to participate as well.
This phase involves the low-level design of the AI solution, and the architects and development leads need to work on various aspects like the process stages, sources of information, the conditions for target actions, dynamic behaviors, etc. You can read more about these in “How to design an artificial intelligence system”.
AI development platforms can expedite the project since they offer the following:
- AI capabilities like ML, NLP, expert systems, automation, vision, and speech;
- A robust cloud infrastructure.
During this phase, you need to evaluate the various AI development platforms, e.g.:
- Microsoft Azure AI Platform;
- Google Cloud AI Platform;
- IBM Watson AI platform;
- Infosys Nia.
You can read “The best artificial intelligence software development tools of 2019” for more insights.
You need your complete development team ready before starting this phase, therefore, you need to induct the AI, web, and mobile developers. Given the complexity of this project, I recommend that you onboard a field expert development team, as I have explained in “Freelance app development team vs. field expert software development teams”.
Different AI development platforms offer extensive documentation to help the development teams. Depending on your choice of the AI platform, you need to visit the appropriate webpages for this documentation, which are as follows:
- Microsoft Azure AI Platform;
- Google Cloud AI Platform;
- IBM Watson Developer platform;
- Infosys Nia resources.
Onboard your testing and DevOps teams before this phase, and look for testers with experience in AI and ML systems. While the fundamental testing concepts are fully applicable in AI development projects, there are additional considerations too. These are as follows:
- The volume of test data can be large, which presents complexities.
- Human biases in selecting test data can adversely impact the testing phase, therefore, data validation is important.
- Your testing team should test the AI and ML algorithms keeping model validation, successful learnability, and algorithm effectiveness in mind.
- Regulatory compliance testing and security testing are important since the system might deal with sensitive data, moreover, the large volume of data makes performance testing crucial.
- You are implementing an AI solution that will need to use data from your other systems, therefore, systems integration testing assumes importance.
- Test data should include all relevant subsets of training data, i.e., the data you will use for training the AI system.
- Your team must create test suites that help you validate your ML models.
You can read more about these considerations in “How to QA test software that uses AI and machine learning”.
You should take into account certain considerations when deploying AI/ML systems, and these are as follows:
- The project team needs a robust internal handoff process between the IT operations and the development teams. Considering AI/ML is new to several organizations, the IT operations team need a sufficient understanding of the development project.
- Deploy the AI/ML solution as a centralized service that the entire organization can tap into.
Read more about this in “How to deploy AI solutions to production”.
This includes post-deployment support, warranty support, and long-term maintenance. You need to have a part of your development team available during this phase since this will help the maintenance team to learn the system.
Planning to launch an AI solution?
This guide to the AI development lifecycle will help, however, such projects are complex. Your team needs appropriate project management, IT architecture, development, testing, and DevOps expertise. You should consider engaging a reputed software development company, and our guide “How to find the best software development company?” can help you to find one.
