Original resume

>Top 0. Introduction:

  • Various experts gathered in "ICT Management Partners Association" established in Nov. 17, 2011, aiming to support particularly SMB in Japan through ICT-enhanced management.
  • ICT system is just a convenient tool, not the object of the organization; corporate staff should be more productive and intelligent to survive in rapidly changing environment. 
  • Agile software development methodology is focussed; which is most effective method not only in developing software but in maintaining it adjusting in today's changeable requirements.
  • "Extremely Rapid Application Development Community (xRAD)" , established in Aug.6, 2013, where IT vendors and users could exchange views. The author is also the head of the xRAD.
  • Also, a related book of rapid software development was published in May 19, 2014.

>Top 1. Productivity of Japan:

  • Productivity Ranking:
    Productivity = GDP (ppp)/# of workers, or GDP (ppp)/working hour
    • Productivity all per worker, 2013: OECD countries: ppp adjusted (below left)
    • Productivity all per hour, 2013: OECD countries: ppp adjusted (below center)
    • Productivity manufacturing, 2012: OECD; exchange rate adjusted (below right)
  • Productivity of Japan:
    • OECD Report (2011) says that Japanese works annually 1,700 hours, compared with other advanced countries are 200-300 hours less (1,400-1500 hours).
    • Japanese productivity is about $40/head, compared with US $60.
    • Part timer: 6/8 hours are practical, but 6/12 hours are big different.

>Top 3. Serious issues in developing ICT system:

  • Inconsistency between corporate goal and function of ICT system
    • Not useful; small percentage (23%) replies that the system is satisfactory.
    • Too slow in development; due to customized software developed by labor-incentive.
  • Problems in ICT system development:
    • Less initiative of the user company:
      1. Less leadership of the top
      2. Too much dependence on the SIer.
      3. First selecting a tool syndrome
      4. insufficiency of project management covering management & ICT
    • Adherence to waterfall-type development:
      1. expensive investment and elongated development period
      2. discrepancy between user's requirement and description of RPF; causing frequent amendments or reworks.
      3. inappropriate operation after the cut over due to rapid environment change.
      4. too much cost for maintenance (70%+), and not enough positive investment (20%+); exact opposite ratio of US/EU.

3. ICTシステム開発上の大問題:

  • ICT化の大きな問題点:
  • システム開発上の問題点:
  • ウォーターフォール型個別開発への偏重:

>Top 4. Diversified development methods of ICT system:

  • Diversified software development:
    1. Waterfall type of development is needed to develop 1) advanced & big system, 2) unique strategic system.
    2. Rapid development method & tools should be quite effective to develop other general business systems used in the background. (particularly differentiation is needed)
    3. In some cases, general business systems could use optimum package software or cloud computing are if available.
    4. Unnecessary customization or add-ons of package software could be costly and unstable.
    5. The trend from using package software to using either cloud computing (due to increasing of available software) or using rapid development tool (due to advent of easy-to-use convenient tools and easiness of maintenance.)
  • Comparison between US and Japan:
    1. US is balanced; customized 33%, package 30%, in-house development 37%; user companies retain lots of SE.
    2. while Japan sticks to customized software development by ICT vendor; customized 80%, package 6%, and in-house development 14%.
  • Role of user companies:
    1. To establish business model, and actively participate making RFP.
    2. To take the initiative in selecting IT Vendor, and other resources.
    3. To have the ability to select 1) rabid development tool, 2) package software, or 3) cloud computing service, as the case may be.
    4. To play the function of project management, operation & maintenance, and risk management.

>Top 5. Why rapid development method is focussed?:

  • No-coding development:
    • In making software, man-hour spent for coding is the maximum, which could be regarded as the minimum value-added jobs; furthermore man-made coding necessarily contains human error, or bugs.
    • These coding can be minimized in case of using rapid development tool.
  • Off-shore outsourcing of this coding jobs could not be a solution:
    • Labor cost is catching up rapidly in emerging countries.
    • Such labor-intentive works are getting unpopular in emerging countries.
    • Thus, use of rapid software development would be a solution.
  • Features of rapid software development tool:
    • Repository:
      1. Business rules management
      2. Design information management
      3. Operation & maintenance management
    • Automatic generation (programming)
      1. Automatic generation into various languages (Java, C, C#, COBOL, Ruby,...)
    • Remarkable features:
      1. Easy change of design by revising business and/or data.
      2. Programming skills are not particularly required.
      3. Automatic designing of database
      4. Flexible change or addition after cut over

5. 超高速が注目される理由:

"What is extremely rapid development?":

  • 1. This sentence contains three terms: "extremely", "rapid", and "development". In Japan, usually young generation like to say, 'extremely cute' (cho-kawaii). The term of extremely is used in the same context. In business, some extreme things may happen, which are usually several % change; in some cases, several ten % change may be possible in exceptional and shorter period. Then what would be the case of several hundred %, or several times of change? People may call such a phenomenon a kind of supernatural, or paranormal, which are separated from usual phenomena. There must be some special reasons in these exceptions. In the case of rapid software development tool has the reasons; which will arrange and collect all data into a visible single database called depository, eliminating human errors as much as possible. It is difficult to make people widely believe such an abnormal situations in any time.
  • 2. What is 'rapidity'? It is used as comparing to the normal works. As any resource has the limit, it is impossible to do everything rapidly. Rapid means to concentrate the resources into some specific (narrower) areas, conversely, the remained resources can be used in other areas. In the case of software development, system engineers need to make coding and debugging in most exact manner, which enforces human expertise and perseverance. By using rapid development tool, humans can concentrate themselves in the area of strength such as business process, organizational structure, priority decision in case of changes, etc.
  • Lastly, 'development' is a challenge to apply what had not been existed nor used technology or know-how in the target. It is essential to recognize meaning or purpose of the development; which would be verified later whether it was really effective or not in the market. Simple acceptance of jobs as the order from the organization could not really motivate the developer. It should be reconsidered that the product was really just respond to the market needs. If there were amendable or insufficient things in the product, the next iteration of development should start, which will be almost advanced maintenance. The end of a cycle of development is the start of the next cycle. (K. Kobayashi, Secretary-General of ICTM-P)
  • 1.超高速開発には3つのメッセージがある。
  • 2.次に高速とは、通常の作業に比べての表現である。資源に限りがある以上、すべてに対して高速にすることはできない。高速作業することは、他で使っていた資源をそこに集中させることであり、逆に高速化したことで余った資源を他に振り向けられるということである。ソフトウェア開発ではSEによるプログラミングおよびそのデバッグ作業を正確に行うことが必要で、その作業には習熟した人間の忍耐を強いてきた。超高速開発によって、今までの人的資源を、もっと人間が得意な分野、即ち、業務プロセスや組織構成のあり方、変更の場合の優先度、社内研修の徹底などに注力することができるようになる。
  • 3.最後に開発とは、今まで存在していなかった、あるいはまだ活用されていなかった技術・ノウハウを実践に応用するということである。それは何のために開発するのかという原点を検証すること、そして後日達成したことが本当に市場で効果的なのかを認識することは重要である。組織の指示通りゆえに開発することでは、真のモチベーションは得られない。製品を市場ニーズとを再度検討し、変更点や不足点あれば、それは次のイテレーション開発になる。それは先進的な維持とも言える。一つの開発の終了は次の新たな開発の開始である。(小林寛三、ICT経営パートナーズ協会事務局長)
