Depending on the context, OST can refer to several completely different concepts—ranging from the musical scores that define our favorite films to powerful product management frameworks and crucial computing data files.
This comprehensive guide breaks down the three most common meanings of “OST”: Original Soundtracks, the Opportunity Solution Tree in product management, and Outlook Storage Tables in computing.
1. OST in Entertainment: The Original Soundtrack
In film, television, and gaming, an OST stands for Original Soundtrack. It refers to the recorded music specifically produced or compiled for a media project.
- What it includes: An OST features background instrumental tracks (often called the score, composed by artists like Hans Zimmer or Ludwig Göransson) alongside vocal songs featured in or inspired by the media.
- Why it matters: Music anchors human emotion. A brilliant OST elevates storytelling, telegraphs character motivations, and creates iconic cultural moments (think of the opening notes of Star Wars or the synth-heavy soundscapes of Stranger Things).
- How to enjoy them: Platforms like Spotify, Apple Music, and YouTube host dedicated playlists and vinyl releases, making video game and anime soundtracks (like NieR:Automata or Persona) standalone cultural phenomenons.
2. OST in Product Management: The Opportunity Solution Tree
Popularized by product expert Teresa Torres, the Opportunity Solution Tree (OST) is a visual decision-making framework used by agile teams to connect business goals directly to customer needs.
