課題とサブタスクを作成する

The building blocks of any project are issues. Issues act as the packets of work that travel through their respective workflows within their projects until the work is completed. There are different types of issues within Jira Work Management, including epics, tasks and subtasks.

An issue can have child issues that can be assigned and tracked individually.

On this page, you'll learn more about creating and converting issues and child issues. You can also import multiple issues via the CSV import.

Learn how to import multiple issues from a CSV file.

For those just getting started, head over to our admin docs to learn how to configure issue types. 

はじめる前に

You need the Create Issue project permission for the issue's relevant project. The type of issues you can create will depend on the issue types your admin has enabled for your project.

課題の作成

Jira の任意の場所に課題を作成する手順は、次のとおりです:

1. 作成を選択します。
2. 課題の概要を入力します。
3. すべての必須フィールドと必要なその他のフィールドを入力します。
   1. Optional: To change which fields appear when you create an issue, select ••• > Show fields. Select Custom fields from the dropdown menu, then choose the fields you want. This will update the fields in the issue you’re currently creating as well any future issues created.
   2. Optional: To create other issues with the same Project and Issue Type, select the Create another issue checkbox. Depending on your configuration and issue creation history, some fields may be pre-populated. Review these before creating the new issue.
4. When you're finished, select Create. 

課題を複製する

課題を複製すると、同じプロジェクト内の課題の複製を素早く作成できます。複製された課題は、元の課題とほとんど同じ情報 (概要、影響バージョン、コンポーネントなど) を保持します。ただし、一部の詳細 (例: 作業ログ、コメント、履歴、Confluence ページへのリンクなど) は複製されません。課題ステータスも対応するワークフローの最初のステップに戻り、解決状況はクリアされます。複製された課題を元の課題にリンクすることも可能です。

課題を複製するには：

1. Open the issue.
2. Select ••• > Clone.
3. If you want to, edit the cloned issue's Summary.
4. If applicable to the issue you're cloning, you can also select:
   
   • Attachments to copy existing attachments
   • Subtasks to copy existing subtasks
   • Links to copy any existing linked issues
   • Clone sprint value(s), including current and closed sprint values
5. Select Clone.

サブタスクを作成する

課題のサブタスクを作成することによって、課題を小さなチャンクに分割したり、課題のさまざまな作業を別々の人に割り当てたりすることができます。サブタスクが課題の解決を遅らせているとことがわかった場合、サブタスクを課題に変換して、作業を独立して行うことができます。ある課題が実質的に大きな課題のサブタスクであることがわかった場合、課題をサブタスクに変換することもできます。

To create a child issue:

1. Open the issue you’d like to be the parent issue. 
2. Select Create subtask under the issue summary.
3. Add an issue summary and select Create.

課題タイプで作業する

Change the issue type in the issue view

課題を作成したあとで課題のタイプを変更し、必要な作業をより良く表すようにすることができます。たとえば、タスクとして起票した課題をバグに変更できます。

1. 作業している課題を開きます。
2. 左上の、課題キーの横にある課題タイプ アイコンをクリックします。
3. 新しい課題タイプを選択します。

新しい課題タイプに別のフィールドがある場合や、別のワークフローがある場合、変更を完了するための [課題の移動] 画面が開かれます。
