Will your current tech stack help you achieve big wins?

How often do you audit your tech stack once, twice, or in a quarter of the year?

Questioning because 50% of founders do the same thing. As projects are successful and capable of driving impact and meeting user expectations conceptually, founders don’t allocate time to auditing the tech stack.

Although startups are at the forefront, they take immediate action to shift and adopt a trend-setting tech stack based on market conditions. Change, evolution, or transformation is the key driver of success. They don’t like to miss the single block that could drive them to success.

If anyone avoids auditing their tech stack, they’re sure to fall behind and pay the price with financial and technical debt. In this blog, we discuss common mistakes, the auditing process for a tech stack, when to audit, why it matters, and more.

Tech Stack Audit: In General, What It Is

After gathering requirements, when a new idea or client project arrives, developers review their tech stack. By "tech stack," we mean all the technologies we use. It includes the tools, components, libraries, integrations, frameworks, and languages essential to shaping the idea into a vision. It affects the organization's productivity, efficiency, and service quality.

Whether it's a startup, a small organization, or a large organization, they need to review their tech stack to ensure successful launches.

Why We Need to Pay Attention to: Tech Stack Auditing Process

If an organization can’t perform a tech stack audit quarterly or every 6 months, it must conduct a systematic evaluation annually. It provides a clear indication of whether we are future-ready, whether we should add something new, or whether we should remove something old. 

Multitude of Benefits of Tech Stack Audit at a Glance

Conducting a tech stack audit is a wise move to keep business operations moving at pace. Mentioning the benefits below:

You Can’t Outperform with an Old Tech Stack

Outdated, inefficient, and incompatible tools and software cause disruption and impact the operations. To accomplish the new wins and profitable projects, it’s essential to update the techstack with advanced integrations as per evolving market demands.

Investigate Performance Blockers

Get insights into vulnerabilities, bottlenecks, and redundancies there. This enables long-term customer engagement, fueling the best user experience and profound trust. 

Scalability Optimization

As market demand evolves, it is essential to reorganize the tech stack to build next-gen, modern solutions that can manage business growth and the enormous volume of data and user base without compromising performance.

Shred off Financial Load

Not all resources and tools are used frequently; some may be needed only once in a blue moon for a specific task. The organization maintains a range of tools and software to ensure work isn’t hampered. But these underutilized tools and resources spike up the financial cost. 

By assessing the tools, it will be clear which are worth keeping and which should be unsubscribed from.

Proof of Trusted Mergers and Acquisitions

Preparing documentation for all software and tools will help avoid misunderstandings or misconceptions. If everything is clearly stated, it becomes easier to activate underused technology when collaborating with tech partners.

Security Shoot up

Even the simple User ID needs to be secured; if this goes public, user privacy will be at risk. Assessing the tech stack on time will reduce the risk of cyber threats and data breaches and ensure compliance with industry standards and regulations.

The Audit Process: When to Perform a Tech Audit

In this section, we’re highlighting the signs that indicate the need to perform a tech stack audit. What should be kept and what should be excluded to reduce the impact on silos?

It's Been a Long Time for a Tech Audit

If the organization continues to collaborate with the new partners, it will overlook the tool's real value. Is it really managing productivity, or is the team struggling? If you don't remember when you performed the audit, do it immediately.

Integration Disrupting Data Silos

Suppose that you need to download the weekly report to showcase a different department. 

Are you collaborating, connecting, and sharing with the same stack? 

Do you need to quickly switch the collaboration mode, report analysis, and presentation? 

Is it taking too long to create the report?

Fear of Security Threats

Outdated software is always on hackers' and intruders' hit lists. Each update is typically rolled out to resolve issues and technical breaches, and to remove unnecessary functionality to improve the system's performance, scalability, and efficiency.

During the tech stack audit, we can evaluate when the app was last updated, whether it is secure enough, and whether it is creating a gateway for hackers.

If the Business Scales up

Businesses expand their product lines in line with market demand to boost brand visibility. While taking this move, it is worth performing a techstack audit. We learn how the new services can meet the legacy system's guidelines and requirements. 

If Integrating New Apps

It is essential to identify gaps between the new integration and the business vision and operations to ensure alignment.

  • Will it make things more complex or easier to manage? 

  • Is it embedded redundancy, inefficiency or obstacles? 

  • Is it easy to launch integration?

  • Will it solve the existing collaboration, data management, and performance issues?

If the User Experience is not as Expected

If the tech stack is complex and can’t serve the team, it just exhausts them, wasting hours and effort. We need to switch the techstack to get things done effectively, reaping optimum outcomes. If the system is out of service or unavailable, then it will impact the user experience.

If you are struggling with the above pointers, it's time to conduct a tech stack audit.

90 Days of Auditing and Shifting to a New Tech Stack

In this section, we outline what you should expect and how to navigate the phases of the tech stack audit. First, what you should do before an audit:

Map and Review the Points to Have a Hassle-Free Audit 

Suppose you are brainstorming to access the latest partnership, tools, and subscription, but have you evaluated your systems for compliance and integrations? How will you know what should be noticed and validated before performing an audit?

Let’s go through every bullet point:

  • From planning through release and monitoring, can your system integrate automated or manual processes?

  • Can your system onboard professionals with proper instructions that comply with standards and principles?

  • Can your team effectively use the automated tools for progress tracking?

  • Is this integrated with AI-powered analytics?

  • Is your team skilled?

  • Do you have cloud-powered solutions that enable seamless integration and updates?

  • Is your team experiencing frequent errors and version-control issues, and is unable to collaborate on the same task in real time?

  • Is your organization's data cluttered, scattered, or well centralized to ensure on-demand, multi-region accessibility?

  • Is the methodology you’ve picked trusted, verified, accurate, automated, or not?

The Right Way to Perform Tech Stack Audit

If you have 1 or 2 items, you can review daily. However, a tech stack is a collection of tools, technologies, and integrations, so it can’t be completed daily or on short notice. It's not the right way to audit the tech stack. Instead, involve all team members to gather their feedback.

The right way to perform tech stack audit

First 30 days

Enlist the Tech Stack Utility Items across the Organization

Make a list of all software, tools, and integrations for in-house, outsourced, and client projects. It must be categorized by department, such as development, operations, marketing, finance, auditing, HR, CRM, ERP, HRIS, and technical support.

  • Also, list how many users depend on the particular technology.

  • How many are temporarily in service, or how many are in daily service?

  • Are these well-integrated with the legacy system?

Estimate the Expense (Subscription/ Merger deadline)

It's normal to pay a fee for every service or product, and if it's wasted on outdated or not worth it products or services, you can eliminate them during this audit and save budget. 

Next 30 days

Forward the Circular

Prepare a form listing all items where team members are facing issues with software or hardware, including functions, operations, memory, or any impact on their day-to-day responsibilities. These collectibles will make decision-making easier.

Assign the Responsibility

Now that you have the list, forward the circular to all stakeholders and team members using the software and tools. Then assign the task to responsible members from each department to gather feedback before deciding whether to keep or exclude the resources and the solution.

In case someone is not responsive to the circular, the assignee will remind them. 

Uninstallation, Installation, and New Integrations

After collecting feedback, you may have an idea of which services or products to exclude from partnerships and subscriptions. Then send an email stating the instructions to uninstall the system and service to prevent their use. 

Last 30 Days

Provide Support for Immediate Outcome

Suppose someone has difficulty uninstalling useless software and forgets to remove it from the system software list. In that case, the concerned person can schedule a one-on-one discussion to understand the reason and arrange the uninstallation.

Final Call for TechStack Audit

Now, obtain a report from all responsible assignees confirming that all unused software, products/ integrations have been uninstalled. Can they end the subscription and merger immediately? Once it is ‘Yes’, the audit process is completed.

It will help founders avoid financial debt and invest in the right assets, aligning the organization's goals.

How to manage the Challenges of Tech Stack Audit?

A tech stack audit is a responsible task that requires attention to detail and strategic planning. If you neglect the measures, it will hinder the organization's operations. 

Let's discuss the key considerations to ensure a smoother process.

Pick as per Priority

Avoid being overwhelmed by taking on too much at once. Strategize and prioritize next steps. Plan the sprints for audit chunks and identify which tools, components, or external integrations should be considered in the first phase.

Verify and Validate the Findings 

Keep your documentation up to date and remove anything older or no longer valuable; this reduces redundancy, clearing clutter and confusion. Collaborate with all stakeholders and verify that the most essential information and findings align with the modern tech stack.

Assign to Skilled Professional

Evaluating the Resources isn’t everyone's job; it can only be done by skilled professionals who can do it responsibly within the given timeline without risk. They know how to navigate complex scenarios and mishaps through mindful resource allocation.

Measure Compatibility for Third-party Integration

Not all third-party tools are compatible with the tech stack; they need specific license access and system access to make the needful changes. It can impact the security and performance of the overall tech stack to prevent mishaps. Best practices and security standards should apply.

Demo Session

Before shifting to new technology, the organization should guide its team members on how to learn the tech stack. Give them time to develop their skills and avoid dependence on legacy systems. Ask them why we are shifting and why this transformation is necessary in the moment. 

Real Life Scenario Tech Stack Audit & Migration Switching from Google Suite to MS Suite

As the section already indicates, we just want to define it here clearly.

An organization in its 4-year infancy is using G Suite, leveraging all apps and services for calling, collaboration, storage, and other capabilities. Everything was smooth, affordable, and driving measurable wins.

By the time the number of client projects increased, work doubled, and they felt the need to standardize.

They had this thought because they have been monitoring market evolution, demand, and trends. They’ve been associated with brand names for the past 4 years and have extensive data from various projects that need to be organized and managed carefully.

To manage this load and drive the business operation successfully, the tech stack needs to be migrated. However, they have scaled their solution offerings with the backing of skilled, intuitive mindsets. However, it's time to move toward transformation. It didn’t happen in 24 hours, but before then, the organization completed the tech stack audit.

They backed up all files, data, and conversations related to both internal and external projects. Then, launched new tech stack integration and asked the team to set up and upload the historical data to move ahead with operations efficiently without leaving any gap.

Common Mistakes to Avoid During a Techstack Shift

Auditing the tech stack is a strategic step towards success and new accomplishments. But sometimes mishaps occur from small mistakes that are far from big wins.

Below we mention a few that can cost significant debt to organizations:

Catching the Big Fish First Can Delay Your Success

Instead of focusing on the complex, it is better to take baby steps and ship and shift slowly. During the process tech stack shift, we committed more than we could deliver. That turned out to be a nightmare hard to forget, wasting our finances, time, and effort.

Don’t Commit to What You Can’t Build

A Fractional CTO will not think to invite chaos; they avoid over-engineering and over-commitment. They set realistic goals and milestones to achieve and manage. They launch services that are easy to manage alongside ongoing projects without disrupting the steady, slow-ship schedule. They take a move from monolith to microservices rather than going directly to microservices.

Aligning the Database as a Requirement, not Just a Trend

Don’t pick the database based on popularity. Suppose someone is using MongoDB, and you have adopted it despite the organization's work being manageable with PostgreSQL. 

In that case, this mismatch will hamper performance, leading to data inconsistencies, caching issues, and more.

It's better to plan before any integration; otherwise, it will delay the development deadline.

Unable to Measure the Bottleneck

Some founders don’t know the root cause when encountering an issue. Suppose the manager is unable to collaborate with the clients or other stakeholders. The problem may be that the right tool and resource are not the same for the client.

A founder first gets to know the problem. If in the initial stage of client project discussion, how would they like to collaborate in which mode or tool would be easier to communicate and be on the same page without switching to different platforms?

Security compliance

If we don’t adhere to security compliance and use tools without a license or permission, it will disrupt operations. It may cause serious issues within organization to not comply the regulations guidelines.

Avoiding the Tracking

Not keeping a log record of activities and processes makes it difficult to measure performance, productivity, and efficiency. Keeping track with profiling tools will help diagnose glitches, bottlenecks, gaps, or impacts on user experience.

To avoid issues, founders should think, measure, and then implement strategies that comply with industry-specific patterns, configurations, and compatible integrations, as per project requirements and training team members.

Conclusion

Anything cluttered, disorganized, or managed from the dark room without proper analysis creates uncertainty and undermines control in any tech organization. It is essential to know what we have to drive the operations, how much we are spending, and what is evaluated through the tech stack audit. The resources we are using should be the latest, compatible, and easy to integrate, rather than outdated or complex. 

Get to know client and team expectations to drive the business efficiently and avoid roadblocks.
