What Is an IT Consultant?<\/h2>\n\n\n\n

An IT consultant<\/a> is a professional who resolves corporate management challenges through IT solutions<\/strong>. Typically, IT consultants belong to a consulting firm and are deployed to client companies.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

Since virtually every company today relies on IT systems, nearly all businesses are potential clients. As a result, demand for IT consultants \u2014 specialists who harness the power of IT to solve corporate challenges \u2014 continues to grow.<\/p>\n\n\n\n

What Does an IT Consultant Do?<\/h3>\n\n\n\n

The core responsibility of an IT consultant is to resolve client companies’ management challenges through IT solutions<\/strong>. The scope is wide, encompassing the following types of work.<\/p>\n\n\n\n

 <\/span>Listening & Analysis<\/strong><\/td>Conduct interviews with executives and IT departments on management strategy, challenges, and workflows; analyze issues<\/td><\/tr>
 <\/span>Proposals<\/strong><\/td>Recommend IT strategies and IT solutions to address management challenges<\/td><\/tr>
 <\/span>Management<\/strong><\/td>Oversee projects such as system development aimed at resolving management challenges<\/td><\/tr>
 <\/span>Problem Resolution<\/strong><\/td>Resolve management challenges through system development and similar means<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Engagements may be comprehensive, covering everything from issue analysis to system implementation proposals, design, testing, and optimization.<\/p>\n\n\n\n

Another hallmark of the role is frequent interaction with senior leadership, given the deep involvement in management direction.<\/p>\n\n\n\n

4 Things SIer and IT Consulting Have in Common<\/h2>\n\n\n\n

SIer and IT consulting share many similarities in terms of job content and required skills.<\/p>\n\n\n\n

    \n
  1. Using IT knowledge to solve client challenges<\/a><\/li>\n\n\n\n
  2. Continuously pursuing new IT knowledge<\/a><\/li>\n\n\n\n
  3. Communication skills are essential<\/a><\/li>\n\n\n\n
  4. Problem-finding and listening skills are required<\/a><\/li>\n<\/ol>\n\n\n\n

    Here we introduce four key commonalities between SIer and IT consulting.<\/p>\n\n\n\n

    1. Using IT Knowledge to Solve Client Challenges<\/h3>\n\n\n\n

    The first commonality is using IT knowledge to solve client challenges<\/strong>. That said, while the role is the same, the purpose differs \u2014 so be careful not to conflate the two.<\/p>\n\n\n\n

    SIers communicate with system users and take on system development projects to resolve their issues \u2014 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 \u2014 an executive-centric approach.<\/p>\n\n\n\n

    Additionally, while an SIer’s scope ends at delivering a system product, an IT consultant’s scope covers proposing systems and defining business requirements<\/strong> \u2014 a key distinction.<\/p>\n\n\n\n

    In either case, the direction of using IT knowledge to solve client challenges is the same.<\/p>\n\n\n\n

    2. Continuously Pursuing New IT Knowledge<\/h3>\n\n\n\n

    The second commonality is the constant pursuit of new IT knowledge<\/strong>.<\/p>\n\n\n\n

    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.<\/p>\n\n\n\n

    SIers also possess knowledge and experience in requirements definition, design, and programming.<\/strong> While IT consultants are not expected to perform hands-on work themselves, practical knowledge is still necessary to drive projects as a team.<\/p>\n\n\n\n

    Both SIers and IT consultants are expected to continuously update their IT knowledge.<\/p>\n\n\n\n

    3. Communication Skills Are Essential<\/h3>\n\n\n\n

    The third commonality is that strong communication skills are essential<\/strong>.<\/p>\n\n\n\n

    Both SIers and IT consultants manage projects by engaging with many stakeholders<\/strong>. Without strong communication skills \u2014 for listening, sharing information, delegating tasks, and coordinating \u2014 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.<\/p>\n\n\n\n

    While SIers and IT consultants differ in role and responsibilities, the importance of strong communication with clients and project teams is a shared requirement.<\/p>\n\n\n\n

    4. Problem-Finding and Listening Skills Are Required<\/h3>\n\n\n\n

    The fourth commonality is that problem-finding and listening skills are required<\/strong>.<\/p>\n\n\n\n

    SIers engage with end users, while IT consultants engage with executives \u2014 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<\/strong>. The ability to identify issues that even the client hasn’t noticed is what enables the right IT solution to be recommended.<\/p>\n\n\n\n

    For both SIers and IT consultants, IT knowledge and technical skill alone are not enough \u2014 advanced listening ability and problem-finding skills are a shared requirement.<\/p>\n\n\n\n

    Differences Between SIer and IT Consulting<\/h2>\n\n\n\n

    While SIer and IT consulting share many commonalities, there are of course differences as well.<\/p>\n\n\n\n

      \n
    1. IT consultants must maintain a consistently high awareness of management and business<\/a><\/li>\n\n\n\n
    2. IT consultants are constantly held accountable for results<\/a><\/li>\n\n\n\n
    3. IT consultants have a broader range of proposals available<\/a><\/li>\n<\/ol>\n\n\n\n

      Here we explain three key differences between SIers and IT consultants, both of whom work with IT systems.<\/p>\n\n\n\n

      1. IT Consultants Must Maintain a High Awareness of Management and Business<\/h3>\n\n\n\n

      IT consultants must develop a strong awareness not only of IT, but of management and business as well.<\/strong><\/p>\n\n\n\n

      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.<\/p>\n\n\n\n

      Beyond IT knowledge, maintaining a high level of professional awareness as a “consulting expert” is expected<\/strong>.<\/p>\n\n\n\n

      2. IT Consultants Are Constantly Held Accountable for Results<\/h3>\n\n\n\n

      Another key difference is that IT consultants are constantly held accountable for delivering results<\/strong>.<\/p>\n\n\n\n

      SIers are expected to deliver the systems and services their clients request \u2014 a genuinely important and responsible role without question.<\/p>\n\n\n\n

      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<\/strong> in order to deliver results.<\/p>\n\n\n\n

      3. IT Consultants Have a Broader Range of Proposals Available<\/h3>\n\n\n\n

      Another distinguishing feature of IT consulting is the wider range of proposals available to clients<\/strong>.<\/p>\n\n\n\n

      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.<\/p>\n\n\n\n

      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 \u2014 not just those from their own company.<\/p>\n\n\n\n

      IT consultants enjoy greater freedom, but that freedom comes with correspondingly higher difficulty<\/strong>.<\/p>\n\n\n\n

      The article below provides a detailed explanation of the differences between IT consultants and SIers.<\/p>\n\n\n

      3 Benefits of Transitioning from SIer to IT Consulting<\/h2>\n\n\n\n

      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.<\/p>\n\n\n\n

      Here are three key benefits of transitioning from SIer to IT consulting.<\/p>\n\n\n\n

        \n
      1. Opens doors for your future career<\/a><\/li>\n\n\n\n
      2. Potential for a salary increase<\/a><\/li>\n\n\n\n
      3. Opportunity to learn deeply about business from an early career stage<\/a><\/li>\n<\/ol>\n\n\n\n

        Let’s look at each in detail.<\/p>\n\n\n\n

        1. Opens Doors for Your Future Career<\/h3>\n\n\n\n

        Moving into IT consulting offers the benefit of opening doors for your long-term career<\/strong>.<\/p>\n\n\n\n

        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<\/strong>, and those experiences expand your career options significantly.<\/p>\n\n\n\n

        While staying in an SIer role typically means advancing along an IT engineering career track, IT consulting opens up diverse paths \u2014 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.<\/p>\n\n\n\n

        2. Potential for a Salary Increase<\/h3>\n\n\n\n

        Depending on your existing career and skillset, the potential for a salary increase when moving into IT consulting<\/strong> is a significant benefit.<\/p>\n\n\n\n

        The average salary for SIer professionals is said to range from 4 to 6.5 million yen \u2014 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<\/strong> for high performers.<\/p>\n\n\n\n

        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 \u2014 logical thinking, presentation, listening, and more \u2014 are demanding, but they reflect the high compensation on offer.<\/p>\n\n\n\n

        3. Opportunity to Learn Deeply About Business from an Early Career Stage<\/h3>\n\n\n\n

        IT consulting offers the opportunity to develop a deep understanding of business from early in your career<\/strong>.<\/p>\n\n\n\n

        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<\/strong>.<\/p>\n\n\n\n

        With major corporations as clients, projects worth tens of billions of yen are not uncommon \u2014 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.<\/p>\n\n\n\n

        3 Drawbacks of Transitioning from SIer to IT Consulting<\/h2>\n\n\n\n

        While there are many benefits to moving from SIer to IT consulting, it’s equally important to be aware of the drawbacks.<\/p>\n\n\n\n

          \n
        1. The need to continually pursue high results tends to increase overtime and workload<\/li>\n\n\n\n
        2. Higher skill demands than SIer mean there’s a risk of struggling to keep up with the volume of information required<\/li>\n\n\n\n
        3. Significantly more meetings than in SIer roles<\/li>\n<\/ol>\n\n\n\n

          Be sure to understand both the benefits and drawbacks before making your decision.<\/p>\n\n\n\n

          1. The Pursuit of High Results Tends to Increase Overtime and Workload<\/h3>\n\n\n\n

          One drawback of IT consulting is that the constant drive for high results leads to increased overtime and heavier workloads<\/strong>.<\/p>\n\n\n\n

          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.<\/p>\n\n\n\n

          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<\/strong> \u2014 which is why overtime and workloads in IT consulting tend to keep growing.<\/p>\n\n\n\n

          2. Higher Skill Demands Mean a Risk of Struggling to Keep Up with Information<\/h3>\n\n\n\n

          Another drawback is that IT consulting demands more input than SIer roles, creating a risk of being overwhelmed and falling behind<\/strong>.<\/p>\n\n\n\n

          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.<\/p>\n\n\n\n

          Furthermore, the daily volume of inputs \u2014 from client meetings to documents and materials \u2014 is enormous<\/strong>. If you become overwhelmed, the trust relationship with your client may suffer as a result.<\/p>\n\n\n\n

          3. Significantly More Meetings Than SIer Roles<\/h3>\n\n\n\n

          Another disadvantage is that IT consulting involves far more meetings<\/strong> than SIer work.<\/p>\n\n\n\n

          SIers are primarily responsible for delivering finished systems, so their work tends to be weighted toward system development rather than meetings \u2014 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.<\/p>\n\n\n\n

          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<\/strong> will help minimize the gap between expectation and reality.<\/p>\n\n\n\n

          Key Selling Points for SIer Professionals Transitioning to IT Consulting<\/h2>\n\n\n\n

          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.<\/p>\n\n\n\n

           <\/span>Selling Point<\/strong><\/td> <\/span>Details<\/strong><\/td><\/tr>

          Common Career Destinations for SIer Professionals<\/h3>\n\n\n\n

          SIer professionals move on to a wide range of destinations, including IT consulting. Common options include the following.<\/p>\n\n\n\n

          5 Key Skills You’ll Need When Targeting IT Consulting from SIer<\/h2>\n\n\n\n

          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 \u2014 use them as a framework for your self-assessment.<\/p>\n\n\n\n
