Many people wonder, “How can I make the transition from SIer to IT consultant?”
The short answer is that transitioning from SIer to IT consultant is a highly recommended career path. SIer and IT consulting share many common elements, making it a destination where you can leverage your existing knowledge and experience. However, you cannot succeed in this transition without understanding the differences between the two. Conversely, grasping those differences puts you significantly closer to a successful transition.
In this article, we’ll cover the differences between SIer and IT consulting, key transition tips, and real-life examples. By the end, you’ll be ready to take your first step toward a new career.
Making the Move from SIer to IT Consulting Is Achievable
Transitioning from SIer to IT consultant is absolutely an achievable career vision.
IT consulting shares many commonalities with SIer work, and the knowledge, experience, and project management skills you’ve built as an SIer will undoubtedly translate well. Your experience in requirements definition, system design, and system development will allow you to hit the ground running.
The IT consulting industry sees many transfers from SIer backgrounds, and demand from firms is genuinely high.
What Is an IT Consultant?
An IT consultant is a professional who resolves corporate management challenges through IT solutions. Typically, IT consultants belong to a consulting firm and are deployed to client companies.
They listen to the client’s management strategies, formulate IT strategies, design systems, and oversee project management toward implementation. The scope of work is broad, requiring strong listening skills, management capabilities, and presentation abilities.
Since virtually every company today relies on IT systems, nearly all businesses are potential clients. As a result, demand for IT consultants — specialists who harness the power of IT to solve corporate challenges — continues to grow.
What Does an IT Consultant Do?
The core responsibility of an IT consultant is to resolve client companies’ management challenges through IT solutions. The scope is wide, encompassing the following types of work.
| Listening & Analysis | Conduct interviews with executives and IT departments on management strategy, challenges, and workflows; analyze issues |
| Proposals | Recommend IT strategies and IT solutions to address management challenges |
| Management | Oversee projects such as system development aimed at resolving management challenges |
| Problem Resolution | Resolve management challenges through system development and similar means |
Engagements may be comprehensive, covering everything from issue analysis to system implementation proposals, design, testing, and optimization.
Another hallmark of the role is frequent interaction with senior leadership, given the deep involvement in management direction.
4 Things SIer and IT Consulting Have in Common
SIer and IT consulting share many similarities in terms of job content and required skills.
- Using IT knowledge to solve client challenges
- Continuously pursuing new IT knowledge
- Communication skills are essential
- Problem-finding and listening skills are required
Here we introduce four key commonalities between SIer and IT consulting.
1. Using IT Knowledge to Solve Client Challenges
The first commonality is using IT knowledge to solve client challenges. That said, while the role is the same, the purpose differs — so be careful not to conflate the two.
SIers communicate with system users and take on system development projects to resolve their issues — a user-centric approach to problem-solving. IT consultants, by contrast, identify management challenges through dialogue with executives and propose system development and other solutions — an executive-centric approach.
Additionally, while an SIer’s scope ends at delivering a system product, an IT consultant’s scope covers proposing systems and defining business requirements — a key distinction.
In either case, the direction of using IT knowledge to solve client challenges is the same.
2. Continuously Pursuing New IT Knowledge
The second commonality is the constant pursuit of new IT knowledge.
Both SIers and IT consultants need deep IT knowledge and up-to-date information on the latest technology to do their jobs. Introducing cutting-edge IT services and deploying IT systems suited to each client’s challenges is how they deliver value.
SIers also possess knowledge and experience in requirements definition, design, and programming. While IT consultants are not expected to perform hands-on work themselves, practical knowledge is still necessary to drive projects as a team.
Both SIers and IT consultants are expected to continuously update their IT knowledge.
3. Communication Skills Are Essential
The third commonality is that strong communication skills are essential.
Both SIers and IT consultants manage projects by engaging with many stakeholders. Without strong communication skills — for listening, sharing information, delegating tasks, and coordinating — work cannot move forward smoothly. By accurately understanding others’ intent and clearly conveying your own ideas through written and verbal communication, you can ultimately deliver satisfaction to clients.
While SIers and IT consultants differ in role and responsibilities, the importance of strong communication with clients and project teams is a shared requirement.
4. Problem-Finding and Listening Skills Are Required
The fourth commonality is that problem-finding and listening skills are required.
SIers engage with end users, while IT consultants engage with executives — the audience differs, but neither can be assumed to be deeply versed in IT. Uncovering the latent needs and challenges of such clients requires asking questions from multiple angles and drawing out their concerns through skilled listening. The ability to identify issues that even the client hasn’t noticed is what enables the right IT solution to be recommended.
For both SIers and IT consultants, IT knowledge and technical skill alone are not enough — advanced listening ability and problem-finding skills are a shared requirement.
Differences Between SIer and IT Consulting
While SIer and IT consulting share many commonalities, there are of course differences as well.
- IT consultants must maintain a consistently high awareness of management and business
- IT consultants are constantly held accountable for results
- IT consultants have a broader range of proposals available
Here we explain three key differences between SIers and IT consultants, both of whom work with IT systems.
1. IT Consultants Must Maintain a High Awareness of Management and Business
IT consultants must develop a strong awareness not only of IT, but of management and business as well.
SIers primarily focus on system development and operations, so many develop a strong awareness around IT and the latest technology. IT consultants, on the other hand, place greater emphasis on supporting client company growth through solving management challenges. Their primary contacts are executives and board members, which means business and management knowledge is essential to earning their trust.
Beyond IT knowledge, maintaining a high level of professional awareness as a “consulting expert” is expected.
2. IT Consultants Are Constantly Held Accountable for Results
Another key difference is that IT consultants are constantly held accountable for delivering results.
SIers are expected to deliver the systems and services their clients request — a genuinely important and responsible role without question.
However, IT consultants are expected to resolve management challenges and improve key business metrics. IT solution implementation is merely a means to an end, and they are held accountable for whether that means was appropriate. For this reason, listening and problem framing are critical components of an IT consultant’s work in order to deliver results.
3. IT Consultants Have a Broader Range of Proposals Available
Another distinguishing feature of IT consulting is the wider range of proposals available to clients.
SIers build their business on providing systems and IT services. As a result, their offerings tend to be limited to their own systems or IT solutions within their serviceable scope.
IT consultants, on the other hand, are compensated for resolving client challenges. They can recommend the most direct path to solving a client’s problem from among any available IT solutions — not just those from their own company.
IT consultants enjoy greater freedom, but that freedom comes with correspondingly higher difficulty.
The article below provides a detailed explanation of the differences between IT consultants and SIers.
3 Benefits of Transitioning from SIer to IT Consulting
Many SIer professionals have considered making the move to IT consulting. Given the strong affinity between the two, it’s a natural and well-suited transition.
Here are three key benefits of transitioning from SIer to IT consulting.
- Opens doors for your future career
- Potential for a salary increase
- Opportunity to learn deeply about business from an early career stage
Let’s look at each in detail.
1. Opens Doors for Your Future Career
Moving into IT consulting offers the benefit of opening doors for your long-term career.
IT consulting involves deeper engagement with management and business compared to SIer work. You also gain access to a broad network of executives and key decision-makers at major companies, and those experiences expand your career options significantly.
While staying in an SIer role typically means advancing along an IT engineering career track, IT consulting opens up diverse paths — transitioning to major corporations, moving into management or strategy consulting, or even starting your own business. Even if you haven’t yet settled on a specific career goal, IT consulting is an exciting and compelling field to explore.
2. Potential for a Salary Increase
Depending on your existing career and skillset, the potential for a salary increase when moving into IT consulting is a significant benefit.
The average salary for SIer professionals is said to range from 4 to 6.5 million yen — not a low figure by any means, reflecting strong demand for SIer talent. However, IT consultants tend to earn even more, and a salary of 10 million yen or more is not out of reach for high performers.
Many consulting firms also operate on a merit-based evaluation model, meaning strong performers are rewarded accordingly regardless of age. The high-level skills required — logical thinking, presentation, listening, and more — are demanding, but they reflect the high compensation on offer.
3. Opportunity to Learn Deeply About Business from an Early Career Stage
IT consulting offers the opportunity to develop a deep understanding of business from early in your career.
In SIer roles, client-facing negotiations and upstream system design work are often reserved for professionals in their 30s or 40s. In IT consulting, however, your primary contacts are client executives and department heads, meaning even junior professionals are entrusted with important work.
With major corporations as clients, projects worth tens of billions of yen are not uncommon — and if your abilities are recognized, you may find yourself involved in those too. The responsibility is significant, but you gain experiences that would typically require a managerial role in a conventional company.
3 Drawbacks of Transitioning from SIer to IT Consulting
While there are many benefits to moving from SIer to IT consulting, it’s equally important to be aware of the drawbacks.
- The need to continually pursue high results tends to increase overtime and workload
- Higher skill demands than SIer mean there’s a risk of struggling to keep up with the volume of information required
- Significantly more meetings than in SIer roles
Be sure to understand both the benefits and drawbacks before making your decision.
1. The Pursuit of High Results Tends to Increase Overtime and Workload
One drawback of IT consulting is that the constant drive for high results leads to increased overtime and heavier workloads.
Client companies pay a premium for IT consultants, and in return they demand results on management challenge resolution with considerable rigor. To meet that pressure, IT consultants often have no choice but to sacrifice personal time in pursuit of high performance.
It is also common for IT consultants to handle multiple engagements simultaneously. Communicating with multiple clients and attending their meetings inevitably leads to a schedule driven by client priorities — which is why overtime and workloads in IT consulting tend to keep growing.
2. Higher Skill Demands Mean a Risk of Struggling to Keep Up with Information
Another drawback is that IT consulting demands more input than SIer roles, creating a risk of being overwhelmed and falling behind.
IT consultants are expected to uncover latent management challenges through dialogue with executives, which requires constantly updating knowledge about the client and their industry from multiple angles. Delivering proposals that satisfy clients is only possible by staying on top of the latest IT technologies and trends.
Furthermore, the daily volume of inputs — from client meetings to documents and materials — is enormous. If you become overwhelmed, the trust relationship with your client may suffer as a result.
3. Significantly More Meetings Than SIer Roles
Another disadvantage is that IT consulting involves far more meetings than SIer work.
SIers are primarily responsible for delivering finished systems, so their work tends to be weighted toward system development rather than meetings — allowing them to work at their own pace to a greater degree. IT consultants, by contrast, are tasked with approaching latent management challenges, which requires attending client meetings to surface and explore issues.
It’s also common to meet with clients multiple times per week to drive toward solutions, with internal prep meetings required on top of that. Going in with the image that work happens in the gaps between meetings will help minimize the gap between expectation and reality.
Key Selling Points for SIer Professionals Transitioning to IT Consulting
When transitioning from SIer to IT consulting, it’s important to know which points to emphasize. No matter how strong your skills and experience, they’re meaningless if you can’t communicate them effectively. Key selling points for SIer professionals moving into IT consulting include the following.
| Selling Point | Details |
| Project Management Ability | Experience overseeing and managing large-scale projects |
| Communication Skills | Communication within teams and with stakeholders |
| Problem-Solving Ability | Experience resolving issues and incidents within projects |
| Technical Engineering Skills | IT skills in design, development, and operations |
| Negotiation Skills | Experience negotiating directly with clients |
| Commitment | Experience meeting demanding client requirements |
Every one of these points is something you can leverage as an IT consultant. Take stock of your skills and experience so you can present them with confidence.
Common Career Destinations for SIer Professionals
SIer professionals move on to a wide range of destinations, including IT consulting. Common options include the following.
| Destination | Characteristics |
| Consulting Firms | ・Develop a broad range of business skills ・Further career advancement potential |
| Startups | ・Flexibility to act on creative ideas ・Opportunity to take on a leadership role early |
| Large Corporations | ・Involvement in large-scale projects ・Stable employment and strong benefits |
| Technology Companies | ・Involvement in cutting-edge R&D ・Opportunity to develop deep technical expertise |
| In-House Development Companies | ・Participate in developing proprietary products ・Satisfaction from seeing your own product reach market |
| Foreign-Affiliated Companies | ・Work on a global scale ・High compensation tied to results |
With so many options available, it’s important to choose based on your skills and where you want to go. Take the time to map out your career plan before beginning your job search.
5 Key Skills You’ll Need When Targeting IT Consulting from SIer
While SIer and IT consulting share much common ground, there are skills that IT consulting demands in particular. Here are five skills you’ll need when targeting IT consulting — use them as a framework for your self-assessment.
- Management ability
- Logical thinking
- Communication skills
- Presentation skills
- Domain-specific expertise
Let’s explore each in detail.
Management Ability
The first skill is management ability.
When an IT consultant’s proposal is accepted by a client, they take on the role of executing the project. Unlike SIers who follow direction from a project leader, IT consultants are in the position of directing SIers. Engagements may also involve coordinating across multiple departments or collaborating with other firms to advance a project.
Leading an entire project in that kind of environment requires a correspondingly high level of management ability.
Logical Thinking
For IT consultants, logical thinking is an indispensable skill.
For an IT consultant, the ability to reason through problems and derive solutions is the product — IT systems are merely the tool. Objective and logical thinking is a prerequisite for identifying the root causes behind the visible symptoms of a client’s challenges.
Furthermore, analysis results and solutions must be grounded in facts and evidence to genuinely resolve a client’s management challenges. Logical thinking is required at every step of an IT consultant’s work.
Communication Skills
Communication skills are an essential requirement for IT consultants.
Uncovering latent management challenges requires proactive, active communication with clients — which means advanced listening skills are directly tied to the quality of outcomes.
Driving a project to success also requires rallying people from a wide range of backgrounds. IT consultants who earn the trust of team members through close communication and exercise genuine leadership are the ones who succeed.
Presentation Skills
Given the nature of the IT consultant role, presentation skills are critically important.
No matter how strong a proposal, it means nothing if the client is not persuaded. Keep the following principles in mind when presenting your recommendations.
- Lead with the conclusion, then explain the reasoning
- Communicate the structure of your talk at the outset
- Limit yourself to the key message — avoid tangents
- Avoid jargon and overly technical language
As your presentation skills improve, you’ll be able to communicate with greater confidence, which in turn builds client trust. Strong presentation skills are a powerful asset for any IT consultant.
Domain-Specific Expertise
IT consultants are expected to possess expertise across a range of domains.
Because IT consultants are needed across virtually every industry, you won’t always be assigned to clients in sectors you’re already familiar with. Resolving a client’s management challenges requires not only IT expertise, but also knowledge of the client’s company and industry. A working knowledge of management strategy is also necessary.
When taking on a project, you’ll need to rapidly build knowledge through books, news, and research papers so you can engage with clients as a true peer.
Useful Certifications for Transitioning into IT Consulting
There are no certifications that are absolutely mandatory for transitioning into IT consulting. That said, leveraging IT solutions to solve management challenges does require a certain level of knowledge and skill. In the job search process, certifications serve as powerful evidence of those capabilities.
Certifications that can be useful when transitioning into IT consulting include the following.
| Category | Certification |
| IT Skills & Knowledge | ・Fundamental / Applied Information Technology Engineer Examination ・IT Coordinator ・ITIL Foundation ・IT Strategist Examination |
| Project Management | ・CompTIA Project+ ・Project Manager Examination ・PMP |
| Business/Management Knowledge | ・Certified Management Consultant (SME Shindanshi) |
| IT Vendor | ・Oracle Master ・LPIC ・CCNA |
Pursue certifications that align with the skills you want to develop.
7 Key Tips for Making the Move from SIer to IT Consulting
Many people wonder, “What should I actually do to transition into IT consulting?” There are seven key points SIer professionals should keep in mind when targeting a move into IT consulting.
- Clarify your motivation for applying
- Compile the skills and experience you’ve built as an SIer
- Assess whether your skills meet the level the firm is looking for
- Include specific projects you’ve been involved in on your resume
- Lead with your conclusion in interviews
- Build knowledge related to management and business
Each point is explained in detail below — use them as a guide for your job search.
Clarify Your Motivation for Applying
As you begin your job search, clarifying your motivation for applying is essential.
There are many career paths available to SIer professionals. Without a clear answer to “why do you want to become an IT consultant?”, your sincerity won’t come through to the consulting firm you’re targeting.
- I want to work in a role that is deeply involved in clients’ business management
- I want to drive projects on a larger scale than I have so far
The more specific and positive your motivation, the better impression it makes during the selection process. Also take the time to summarize — for each firm you apply to — what you find compelling about them, how you can contribute, and what kind of work you’re hoping to do.
Compile the Skills and Experience You’ve Built as an SIer
Take stock of the skills and experience you’ve developed as an SIer. Compared to many other backgrounds, SIer professionals have a high affinity with IT consulting, with much that carries over directly.
- IT knowledge and technical skills
- Client-facing negotiation experience
- Project management experience
Highlight your SIer capabilities, and if you have experience in work that overlaps with consulting, make sure to actively promote it. By weaving in past stories and examples to help the firm envision you succeeding as an IT consultant, you’ll significantly improve your chances.
Assess Whether Your Skills Meet the Level the Firm Is Looking For
When making a career move, the balance between your skill level and what the firm expects is crucial. Consulting firms primarily evaluate candidates on the following criteria.
- Domain knowledge
- Project management skills
- Communication skills
- Potential
Younger candidates may be hired based on potential even if their domain knowledge and skills are still developing. However, candidates in their 30s and above should assume they are being evaluated as immediate contributors. Make sure your skill level genuinely matches what your target firm is looking for before applying.
Include Specific Projects You’ve Been Involved In on Your Resume
When applying, be specific about the projects you’ve been involved in on your resume.
Your resume is the document where you make a detailed case for your career history and skillset. Consulting firms use it to assess your experience and abilities before deciding whether you’re a strong candidate. If the interviewer concludes from the paperwork that you “haven’t done much of note,” an offer will be difficult to come by.
- What projects did you work on?
- What role did you play?
- How did you contribute to results?
Use your experience to make a compelling case that you can hit the ground running as an immediate contributor.
Lead with Your Conclusion in Interviews
A golden rule of interviewing: always lead with your conclusion when answering questions.
IT consultants regularly engage with busy executives and department heads, which means concise and clear communication is a core expectation. Anyone who rambles without getting to the point will be perceived as lacking the fundamentals of a consultant.
Leading with your conclusion also demonstrates logical thinking ability. It helps to practice frameworks like the “PREP method” (Point, Reason, Example, Point) to organize and communicate your ideas clearly in everyday settings.
Build Knowledge Related to Management and Business
If you’re targeting IT consulting, make sure to build your knowledge of management and business.
As an IT consultant, you’ll have frequent interactions with executives. Holding your own with business leaders on the front lines requires more than IT knowledge — you’ll need insight into management, economics, business trends, and global affairs. When conversations align, trust is built, and deeper management discussions become possible.
Make it a habit to read books and follow the news, keeping your antenna tuned to what’s happening in the world.
Identify Your Strengths Clearly
If you want to make a successful transition into IT consulting, identify your strengths clearly.
Even if you make it to the interview stage, simply expressing what you want won’t win you an offer. Motivations like “I want a higher salary,” “I want to work on bigger projects,” or “I want to be closer to management” don’t carry much weight with consulting firms. What brings you closer to an offer is clearly articulating your strengths and future vision, as shown below.
- What are your strengths?
- How can you contribute to the consulting firm?
- In which area do you want to make your mark going forward?
To make a firm want to hire you, identify your strengths clearly and articulate the specific value you can offer.
Salary After Transitioning from SIer to IT Consulting
In most cases, your salary will increase when you move from SIer to IT consulting. That said, be prepared for the fact that higher pay comes with higher expectations.
Here is a general overview of IT consultant compensation by level.

| Senior Consultant | 7–9 million yen | 25–35 |
| Manager | 9–14 million yen | 28–40 |
| Senior Manager | 13–18 million yen | 32–45 |
| Partner | 20 million yen+ | 35+ |
Consultants and senior consultants work in execution roles under direction. Managers and senior managers, on the other hand, take on accountability as project leads — a position that carries significant pressure and responsibility over financial outcomes.
Given the weight of the role, earning over 10 million yen as an IT consultant is achievable, but it requires strong project management skills and a resilient mindset.
Real-Life Examples of SIer-to-IT Consultant Career Changes

- Age 30 — Moved from an independent SIer (4.7M yen) to IT consultant (7.1M yen)
- Age 45 — Moved from a domestic SIer (9M yen) to IT consultant (11M yen)
As shown above, transitioning into IT consulting has delivered salary increases of 1 million yen or more compared to SIer roles. The examples also span a wide age range, showing that a career change in your 40s is entirely achievable.
If you’re currently working as an SIer and considering a career move, it may be well worth exploring IT consulting as your next step.
