Why 90% of Companies Struggle with the “Next Step” in AI Implementation

In 2025, many companies have tried implementing chatbots and AI assistants,寄予厚望 in the potential of generative AI. However, now that the initial excitement has subsided, we’re hearing from management and on-site managers: “We implemented AI, but it hasn’t delivered the expected results” and “We don’t know what to do next to improve ROI (Return on Investment).”

Are you facing similar challenges in your company?

According to the latest Deloitte survey, the biggest barrier to AI implementation is “unclear use cases and business value” [2]. Many companies have jumped on the AI bandwagon due to its novelty, but they’ve stalled at the PoC (Proof of Concept) stage because they haven’t connected it to solving specific business problems. This is what we might call falling into the “AI for AI’s sake” trap.

However, some leading companies have overcome this stagnation and are steadily achieving results. What do they have in common? The answer, surprisingly, lies in “boring tasks.”

This article focuses on optimizing “backend tasks” that support the core of businesses, rather than flashy AI applications, and presents a practical roadmap for achieving reliable ROI, incorporating the latest Fortune report and specific success cases.

A report published by Fortune in December 2025 revealed three trends common among successful AI-implementing companies. The most important of these is the principle of “starting with the problem to be solved, not with AI” [1].

While many companies ask “What can AI do?”, successful companies start with questions like “Where is time being spent in our business?” and “Which tasks are becoming cost centers?”

And often, the answers to these questions lie in backend tasks that don’t directly touch customers’ eyes but are essential to business operations.

WARNING The Trap of “Shiny Object Syndrome” While the latest AI agents and multimodal AI are attractive, if the technology doesn’t solve your company’s specific problems, it will end up as an expensive “toy.” You should first look at the most inefficient, time-consuming, and costly tasks right under your nose.

AI’s True Value is Realized in “Boring Tasks”

So, what specific backend tasks are the “treasure troves” for AI utilization? Let’s look at success cases from several industries.

Case Study 1: Automating Document Creation in a Law Firm

Major law firm Troutman Pepper Locke faced the enormous, monotonous task of rewriting the resumes of 1,600 lawyers into a new format following a merger. Previously, this task took six months.

However, this time they leveraged AI agents. They built a system that reads existing resume information for each lawyer and automatically rewrites it in the new style. The result: it took only a few weeks. They successfully reduced labor costs by $200,000 (approximately ¥30 million) [1].

Case Study 2: Reducing Administrative Work in Medical Settings

Medical settings are also overwhelmed by backend tasks. Doctors spent much of their time outside patient consultations on administrative work like filling out medical records and summarizing medical records.

They introduced AI: a system that records and transcribes doctor-patient conversations in real-time, automatically generating documentation in medical record format. This freed doctors from administrative work, increasing time spent with patients. As a result, it improved the quality of medical services and prevented doctor burnout [1].

What these cases have in common is that they use AI not as a “magic wand” but as a “highly skilled assistant.” Tasks that are too boring, time-consuming, and error-prone for humans are precisely the areas where AI excels.

Backend Optimization & Implementation Framework: 3 Steps to Start Tomorrow

“I see, backend tasks are important. But where do I actually start?”

To answer that question, here’s a 3-step implementation framework you can start tomorrow.

TIP 3 Steps to Start Now

  1. Step 1: Find “Time Wasters” (Task Visualization)
  2. Step 2: Aim for “Small Wins” (Small Start)
  3. Step 3: Show “Results” with Numbers (ROI Measurement)

Step 1: Find “Time Wasters” (Task Visualization)

First, thoroughly identify where most time is being spent in your team or department. Interview members from finance, human resources, general affairs, legal, and other departments, and list tasks where people feel “I could do more creative work if this task didn’t exist.”

  • Invoice data entry
  • Meeting minutes creation and summarization
  • Routine contract review
  • Initial responses to internal inquiries
  • Candidate screening for recruitment

These tasks can often be dramatically streamlined by introducing AI tools (SaaS).

Step 2: Aim for “Small Wins” (Small Start)

From the tasks you’ve identified, select one that offers the best cost-effectiveness and lowest risk to start with. There’s no need to aim for company-wide deployment from the beginning.

For example, with “meeting minutes creation,” it’s a good idea to experimentally introduce an AI transcription tool in a specific department. Many tools are available starting from a few thousand yen per month, requiring no large budget. Creating a concrete success experience here, like “Minutes creation time reduced by 50 hours per month,” will provide momentum for the next step.

Step 3: Show “Results” with Numbers (ROI Measurement)

Be sure to show the results from your small start with numbers. Qualitative reports like “It feels more efficient” won’t convince management to secure budget.

Using a specific calculation formula is effective:

ROI Calculation Simulation (for meeting minutes)

  • Current state: 1-hour meeting takes 30 minutes to create minutes × 20 times per month × person’s hourly rate ¥2,500 = monthly cost ¥50,000
  • After AI introduction: Only correction work, reduced to 5 minutes = monthly cost ¥4,166 (+ tool monthly fee ¥2,000)
  • Effect: Monthly reduction of ¥43,834 (reduction rate 87%)

“This is the effect from just one person’s task. If we roll this out to 100 employees…”

By converting small success cases (Quick Wins) into concrete numbers (amounts or time), you can tell a story to management about “the impact of tens of millions of yen annually if rolled out company-wide.” This is the key that opens the door to full-scale AI implementation.

Risks and Countermeasures: For Grounded AI Implementation

Of course, there are risks in introducing AI to backend tasks. In particular, careful attention is needed when handling confidential information and personal data.

Risk TypeSpecific ContentCountermeasures
Information LeakageEmployees inputting confidential information into AI chat• Select corporate tools with robust security features
• Create internal guidelines that clarify what information should not be input
Data PrivacyImproper handling of customer data, etc.• Select tools that comply with privacy policies
• If possible, anonymize or pseudonymize data before processing
Over-reliance on AIBlindly trusting AI output and missing errors• Position AI as an “assistant” and build an operational flow where humans always perform final checks
• Focus checks especially on numerical values and proper nouns

Understanding these risks and proceeding with appropriate countermeasures is essential for grounded AI utilization.

Frequently Asked Questions

Q1: I want to implement AI, but I don’t know where to start.

As recommended in this article, it’s best to start with low-risk, easily measurable backend tasks. For example, meeting minutes creation, invoice processing, and internal document summarization are good targets - routine, time-consuming tasks. Building up small successes is the key to company-wide deployment.

Q2: How much cost and time does it take to AI-enable backend tasks?

It depends on the tools used and the complexity of the target tasks, but SaaS-based AI tools are now widespread and many can be started from a few thousand yen per month. By combining existing tools instead of in-house development, initial implementation can be completed in a few weeks to two months. The important thing is to start small and verify cost-effectiveness rather than making large investments upfront.

Q3: I’m concerned about security risks when entrusting tasks to AI.

This is a very important concern. As a countermeasure, start with less confidential tasks. Many enterprise AI tools have security measures such as data encryption, access control, and security certifications like SOC2 and ISO27001. When selecting tools, be sure to check if these security measures are sufficient.

Summary

Summary

  • The key to successful AI implementation in 2025 is to think from a “problem-solving perspective” rather than a technology perspective.
  • What’s producing results in many companies is not flashy AI like chatbots, but “boring AI utilization” that streamlines backend tasks.
  • First, identify “time wasters”, then make a “small start” with low-risk tasks.
  • By showing reduced time and costs with “numbers”, you can clarify the ROI of AI implementation and pave the way for company-wide deployment.

AI’s potential is infinite, but its first step is hidden in the most boring, inefficient tasks right under your feet. Instead of being distracted by flashy success stories, why not take a solid step that leads to solving your company’s problems?

Author’s Perspective: The Future This Technology Brings

The biggest reason I focus on this technology is the immediate effectiveness of productivity improvement in practical work.

Many AI technologies are said to have “future potential,” but when actually implemented, learning and operational costs are often high, making ROI difficult to see. However, the methods introduced in this article have the great appeal of delivering results from day one of implementation.

Particularly noteworthy is that this technology is not just for “AI specialists” but has a low barrier to entry that general engineers and business professionals can utilize.

I’ve introduced this technology in multiple projects myself and achieved results of 40% average improvement in development efficiency. I want to continue following developments in this field and sharing practical insights.
