Tech Interview: In-house development or Third-party Solutions? Why?

In partnership with

Hey Impactful PM! It’s Aneesha :)

If you follow me on Linkedin you know by now I love the tech and strategy side of product management 😋.

I have been speaking to a few tech PMs lately. I found something interesting that I thought I should share with you today, dear subscriber.

You see, these tech product managers are often, if not daily, met with a complex question when building products: Should you build this solution in-house or simply get a third-party solution to do it? Whatever the choice, justify why.

It’s popularly known as the “Build or Buy decision”.

Tell you what? This is also a VERY common product management interview question! And this is the best opportunity for me to help you answer this smartly - SAVE IT or LOSE IT!

Understanding the Decision-Making Process 🧠 

Interviewer:
Let’s start with the basics. What are the first factors you consider when deciding whether to build a feature in-house or use a third-party solution?

Interviewee:
The decision to build in-house or leverage a third-party solution begins with understanding the problem we’re trying to solve. Here are the first factors I consider:

1. Core Competency: We need to assess whether the feature aligns with our core competencies. If it’s central to our product offering and unique to our value proposition, building in-house might be the best option. However, if it’s a standard feature that doesn’t differentiate us, a third-party solution might suffice.

2. Time-to-Market: We also need to evaluate the urgency of the feature. If we need to launch quickly to stay competitive, a third-party solution can provide a faster path to deployment compared to building from scratch.

3. Cost Analysis: Cost is always a critical factor. Building a feature in-house requires not just development resources but also ongoing maintenance. On the other hand, third-party solutions often come with subscription fees but may save us development time and effort.

4. How big of a problem does it solve: How critical is the feature to the overall product success and user experience? If it solves a major pain point or unlocks significant value, investing in in-house development might be justified. For less impactful features, a third-party solution could be sufficient.

In short, the initial decision revolves around our core competency, time constraints, and cost implications.

Observation 💡:
The interviewee presents a comprehensive overview of the foundational factors guiding the decision-making process. Their emphasis on core competencies demonstrates an understanding of strategic alignment, while the consideration of time-to-market and cost highlights their practical approach to prioritizing needs.

Evaluating Long-Term Implications 🛣️ 

Interviewer:
That makes sense! Once you've assessed the initial factors, what long-term implications should you consider?

Interviewee:
When evaluating long-term implications, I look at several key aspects:

1. Scalability: Will the feature need to scale with user growth? In-house solutions can be tailored to scale effectively, while third-party solutions may have limitations based on their infrastructure.

2. Customization: We must consider how much customization we need. If we foresee the need for frequent updates or tailored features, building in-house allows us to make those changes more flexibly.

3. Vendor Stability: If we choose a third-party solution, it's crucial to evaluate the vendor’s stability and support. A vendor going out of business or discontinuing their service can pose significant risks to our product.

4. Integration: Lastly, we need to think about how well the solution integrates with our existing systems. Third-party solutions might offer quick wins, but if they don’t integrate well, they can create more headaches than they solve.

In summary, it’s essential to assess scalability, customization needs, vendor stability, and integration challenges when considering long-term implications.

Observation 💡:
The interviewee highlights critical long-term factors that demonstrate their strategic thinking. Their focus on scalability and customization shows a strong awareness of future growth, while the concern about vendor stability reflects their understanding of risk management in product development.

User Experience Considerations 📺️ 

Interviewer:
Great insights! How do user experience considerations factor into your decision?

Interviewee:
User experience is paramount when deciding between in-house development and third-party solutions. Here’s how I approach it:

1. Consistency: In-house development allows us to maintain a consistent user experience across all features. If we rely on third-party solutions, we must ensure that they align with our overall design and functionality.

2. User Feedback: I also look at user feedback. If our users have expressed a desire for a particular feature, we need to consider how well a third-party solution can meet those needs compared to a tailored in-house solution.

3. Performance: We should evaluate the performance of both options. A third-party solution may be easier to implement but could suffer from latency issues or bugs that degrade the user experience. An in-house solution allows us to control performance more directly.

Ultimately, a user-centric approach is crucial in making the decision, ensuring we prioritize user needs and experiences.

Observation 💡:
The interviewee emphasizes the importance of user experience, showcasing a strong understanding of user-centered design principles. Their focus on consistency, user feedback, and performance illustrates a holistic view of how feature choices impact the end-user experience, reflecting their commitment to product quality.

Team Capacity and Expertise 🧑‍🤝‍🧑

Interviewer:
Makes sense. What other factors do you think could influence your decision?

Interviewee:
Team capacity and expertise are also vital in this decision-making process! Here are the key points I consider:

1. Skillset Availability: We need to assess whether our team has the necessary skills to build the feature in-house. If we lack the expertise, it could lead to delays and suboptimal outcomes.

2. Workload: I also consider the current workload of our development team. If they are already stretched thin, adding a new feature might hinder other critical projects. In this case, a third-party solution may relieve some pressure.

3. Learning Opportunities: Building in-house can be a valuable learning experience for the team, enhancing their skills and capabilities. If we believe that the feature will provide growth opportunities for our team, that could justify the decision to build.

In summary, understanding team capacity and expertise can significantly influence whether to build in-house or seek third-party solutions.

Observation 💡 :
The interviewee recognizes the importance of team dynamics and capabilities in the decision-making process. Their attention to skillset availability and workload demonstrates a thoughtful approach to resource management, while the mention of learning opportunities reflects a commitment to team development and growth.
