老朽化したERPアプリケーションが変革の足かせになっている場合、リプレース (再導入) が唯一の解決策と考えられがちである。しかし、リプレースは一般的にリスクが高く、コストもかさみやすいため、日本のアプリケーション・リーダーは、リノベーション (改修) とどちらが良いのかを評価すべきである。
日本の組織の多くは、ビジネスの変化に迅速に対応できるERP戦略を持ち合わせておらず、要件を満たすためにERPへの過度なカスタマイズを行ってきた。
時代遅れのERP戦略に基づく組織は、ERPに問題がある場合、全面的なリプレース (再導入) が唯一の選択肢であると考えがちである。その際、リプレースは複雑かつ高リスクな施策であるという点が見過ごされている。
コンポーザブルなアプリケーション戦略とロードマップに基づいて、段階的に個々の構成要素を改良していくリノベーションの方が、現実的で適切な場合がある。
ERP戦略に責任を持つアプリケーション・リーダーは、以下を行う。
Gartnerのビジネス・ケイパビリティ・モデルに基づいて現在のERPアプリケーションを評価することで、将来のビジネス目標の実現に向けた機能の過不足を把握し、組織の戦略とERP機能の開発計画との整合性を確保する。
Gartnerのペース・レイヤ・アプリケーション戦略に基づいてERPの範囲を再定義した上で、その不足機能をリノベーションで十分に補える場合は、多くの時間と要員を要する高コストなERPのリプレースを回避する。
将来のビジネス目標と、コンポーザブルERPへと向かう市場トレンドを踏まえつつ、定期的にERPの機能範囲を見直す。この作業を通じて、経営層やビジネス部門のリーダーがリプレースとリノベーションのどちらが適切かを判断できるよう、継続的に支援する。
