BYODの背景と現状

最近、記事などでBYODという言葉をよく目にする。BYODとは、Bring Your Own Deviceの頭文字で、企業の従業員が、自分で加入したスマートフォン（以下、スマホ）あるいはタブレットを職場でも使う傾向を指す。
今のBYODとは、従業員が初めて仕事用にスマホを使うことを意味するのではなく、会社のものと平行して使っていた個人のAndroidあるいはiOSデバイスをそれまで仕事用に使っていたBlackBerryなどに代わって使うことを意味することを強調したい。2009年まで縄張りだった北米市場（米国とカナダ）におけるRIM社（BlackBerry）の凋落は、こうした傾向を裏付ける。
BYODを実現するためには、会社側でもいくつかの前提条件がある。従業員はまず会社以外の場所でも、スマホあるいはタブレットで「会社と接続する」ことを習慣にする必要があり、会社もそれに対応できなければいけない。また、特にセキュリティにおいて、端末（機種）とそこで使うアプリケーションの多様性・異質性などが会社のITインフラの課題でもあるが、会社側にとって、仕事の効率や、従業員のモチベーションを高める機会としても捉えたい。
本稿では、BYODの背景、利用事例と影響を探る。とくに、BYODの恩恵を受けるプレーヤー、またBYODで打撃を受けるプレーヤーを考察する。

The term "BYOD" is in the news a lot these days. BYOD is short for Bring Your Own Device, and refers to employees who bring their own smartphone or tablet to the workplace. A common example of use of personal iPads for memo-taking or presentations.
While the penetration of smartphones is one factor behind BYOD, another is that employees were already using their mobile phones or earlier smartphones for so-called PIM functions, such as email, calendar and contact management. Meaning, the BYOD we see today isn't the first time employees have used smartphones at work; rather, it means that they are using their personally owned smartphones (generally, an Android or iOS phone) instead of the BlackBerry or other device they had been using for work in parallel to their personally owned line. The rapid decline of RIM in the North American market since 2009 is evidence of this.
There are several requirements to make BYOD work at the workplace. While obvious, there needs to be WLAN available (to BYOD phones) in the office. Employees need to be in the habit of connecting to the workplace when not in the office, and companies need to enable this. Simply put, when employees bring in their own smartphone into the workplace, that also means they bring it out again, either home or elsewhere. This is a good opportunity to increase productivity.
BYOD represents a security issue for business IT infrastructure, given the heterogeneity of applications and smartphone models that will be touching company resources. However, it is an opportunity for increased productivity and increased motivation, since employees will be able to use the device of their preference.
In this report we explore what's behind the BYOD trend and various use cases. In particular, we explore players who benefit from BYOD, and those who are hurt by it.
