企業力UP 優れたCSRのつくり方 (2012)

thread

弁護士法人 飛翔法律事務所 (編集)

2017年だったと思いますが、大阪のセミナーに参加した時に、その著者から頂いた本です。CSRとは、Corporate social responsibility、企業の社会的責任を指すようです。今流行りのSDGsに近いのではと思います。企業アピールの一種であり、それ以上でも以下でもない感じがします。また、私にはあまり関係ないかな。

ブロックチェーンという新技術についての、2日間にわたるオンラインイベントです。本日1日目に参加しました。

この半年、同技術の情報収集をしていました。結果、おおよそ最新の情報を仕入れられているな、と思いました。その一方、私の情報はB2Cに関するものであり、どうやらB2Bの世界でも活発な動きがあるようでした。本日の登壇者の中にも、B2Bの動きを知らない方がいらっしゃったのではないでしょうか。

現在は、各社、同技術を使って何が出来るかを試行錯誤しながら、我先にと、何らかのサービスを計画している状況です。関係なさそうに見える会社でも、そこは大企業の利点、取り敢えず研究開発費を捻出し、いざという時に動けるようにしている印象を受けました。

ブロックチェーン・プログラミング 仮想通貨入門 (2017)

thread

山崎 重一郎 (著), 安土 茂亨 (著), 田中 俊太郎 (著)

ビットコインバブルの2017年に発行された本。現在なら、技術者としては、イーサリアムの方に人気があるかも知れません。

元々のビットコインのソースコードはC++らしいですが、有志による開発か、JavaScriptなどの別のプログラミング言語でも準備されているのは驚きました。この本ではRubyで説明していますが、Rubyは日本でしか使われない事、また私も使わない事から、実践的な面で残念。ジムで自転車に乗りながら理解できるような内容ではありませんが、ブロックチェーンの概要を知るきっかけになり、貴重な本だと思いました。

株の勉強の成果 2

過去のブログを振り返ると、投資を初めて早7年になるのですが、去年から、個々の日本株とその会社を調べるようになりました。その関係で、これまた早6年になるのですが、先程、飛騨高山へ行った時に泊まったホテルの領収書を見つけたのですが、そこに書かれていた運用会社が、先日まで持っていた株の会社と分かり驚きました。

株の勉強の成果 1

株購入の検討で、ある会社を調べていたところ、故祖父の家の近くにあるゴルフ場を含む、複数のゴルフ場を運営していた会社と分かりました。更に、コロナ禍により、ゴルフ場運営から撤退し、年末年始に、中国資本らしき会社に譲渡した事が分かりました。

もう少し歳を取ったら、そのゴルフ場に通いたいと思っていました。閉鎖する訳ではなく、そこで働く人達は変わらない事を祈ります。

PRINCE2 Agile behaviors

thread
PRINCE2には、プロジェクト管理の基盤になる、Principlesと呼ばれる7つの項目があります。PRINCE2にアジャイルを適用するに当たり、Principlesに、下記の5つの追加項目を加えると、上手く機能するようです。あまり共感出来ない記述がありますが、もう少し理解を深めると、納得いくかも知れません。全体に、やはりITIL 4に似た印象を受けます。

  1. Transparency
    The more information that is out in the open, the better this is for the agile way of working. It enables speed, clarity and engagement, even if the news is not so good.

  2. Collaboration
    A motivated and respectful team is greater than the sum of its parts if people work together and provide cover for one another. More can be achieved this way than working in silos. Collaboration is not just internal to the team: it involves external collaboration with all stakeholders, especially the customer. Fully engaging with customers and working with them, rather than for them, will create shared understanding and ownership of goals and outputs.

  3. Rich communication
    People should always use the most effective channel to communicate. Using face-to-face and/or visualization are many times faster and more effective than words on their own. A rich communication environment should be created, allowing information to pass freely in a culture of commitment and trust. There is still need for documentation, but by using other more effective channels, it can be replaced or complemented and greatly reduced.

  4. Self-organization
    The people closest to the work will usually know best how to get the job done. Therefore people should be trusted to do it. If they create a plan, then they own it and buy into it; it is far more likely to happen if they do. Self-organizing creates mutual respect. A project manager can leave a team manager to focus on product delivery, thereby making team manager feel trusted. This principle extends far beyond the work. It includes the way the team works and the way team members behave towards one another. Although the project board is ultimately accountable for the direction of the project as a whole, the more a team is empowered at the delivery level, the more likely it is to perform well when working in an agile context and achieve the outcomes and goals of that direction.

  5. Exploration
    Projects are difficult, and in order to create "the right thing" you need to be able to work out what "the right thing" is. Frequent question and rapid feedback loops in any form provide an opportunity to learn. Learning helps to improve the products. However, feedback will not just happen; it needs to be sought out collaboratively with people such as the customer, customer representatives, other team members or stakeholders.

富裕層に学ぶ外貨建て投資 (2019) 2

尾河 眞樹 (著)

外貨建て投資というと、ドル建てで投資するイメージがあります。しかし、日本の証券会社などが用意している、外国の株や債券の投資信託でも、外貨建て投資となるようです。その認識で、同著を読み直しました。新興国の章が参考になるかと思います。

The five targets behind flexing what is delivered

thread
プロジェクトの効率化のため、成果物に要求される局面(時間・コスト・品質・スコープ・リスク・利益)の内、何を柔軟に捉えられるかについての5つの項目です。プロジェクトを進行中、良く悩む点で、参考になります。ITIL 4に似た印象を受けます。

It is very important to understand the thinking behind flexing what is being delivered and not just do it "because that's what the manual says". The following sections outline the deeper and more specific reasons why PRINCE2 Agile involves basing the way a team thinks and acts on a different paradigm from that on which projects have traditionally been based.

  1. Be on time and hit deadlines
    Being on time and hitting deadlines has many very significant advantages.

    For any project or piece of work being on time is naturally seen as desirable, but the advantages that meeting deadlines creates may not all be obvious; when the many upsides of this are taken together, it creates something that should be seen as essential as opposed to just desirable.

    Some of these advantages can include:

    • delivering early realization of benefits, and these can be planned around
    • helping with planning (e.g. dependencies within a project or between projects, capacity and resources at the portfolio and programme level)
    • giving confidence (e.g. with progress)
    • there mat be no choice (e.g. external market forces or regulatory considerations)
    • reducing the likelihood of cost overruns (assuming that resources are fixed)
    • improving reputation (e.g. with the customer)

  2. Protect the level of quality
    Ensuring that the level of quality is protected and regarded as vital is of paramount importance to a project. This will lead to a lower cost of ownership throughout the lifetime of the final project.

    PRINCE2 Agile protects the level of quality and ensures that deadlines are met by reducing the amount delivered by the project but not reducing activities that ensure that the quality level is met.

  3. Embrace change
    Embracing change by seeing it not only as inevitable but also as a positive influence on a project allows for a more accurate final project.

    It is important to distinguish between minor change and major change because only the former can be handled dynamically and with little overhead. This illustrates the importance of setting the project baseline in the project initiation documentation (PID) at the correct level.

  4. Keep teams stable: do not add people to a team in order to try to go faster
    Keeping a team stable over the short term removes the temptation to add people to a team in order to catch up with work when in reality it is more likely to have little or no effect.

    Changing team members or adding to the team can have a far more detrimental effect than normal for reasons such as:

    • time is spent bringing new team members up to speed.
    • the number of communication lines in the team grows exponentially.
    • there is an opportunity cost incurred to the areas providing the new people.
    • The team dynamics change and need to be re-established.

    The impact of changing a team's dynamics is usually underestimated and can sometimes be the most counterproductive side-effect of the four.

  5. Accept that the customer does not need everything
    Accepting the premise that not everything defined in the initial stages of a project must be delivered is wise. It inevitably turns out that many things do not add enough value to warrant delaying the project because of them.

    A project using PRINCE2 Agile does not set out with the intention of not delivering everything, but it does aim to hit deadlines and protect the level of quality by reducing what is delivered accordingly. This in turn can result in the early delivery of a minimum viable product (MVP), an in general terms the project delivers what the customer really wants (or needs) more quickly.
