A platform is the technology a company depends on to run its products or essential services. For a CTO, the core platform usually means the client-facing systems the company develops, maintains, and operates—not office laptops, printers, or mail servers. In a small company, one person may be responsible for both. section 1.1
A working platform is not necessarily a healthy one. An established company may rely on aging systems that are increasingly difficult to fix or extend, while no one owns their long-term viability. A first CTO must assess that risk without assuming every system needs immediate replacement. section 1.2.3
An established company's decision
Development and support staff keep the business running on older PowerBuilder, Microsoft Access, or Visual Basic systems. Management considers an expensive off-the-shelf suite. Before committing, identify which capabilities the business actually needs, what is becoming hard to maintain, and which failures would interrupt service. A full suite may be more than the company requires; doing nothing may leave it exposed. section 1.2.3
“Platform” can also mean a supporting tool rather than the company's core system. For video interviews, choose for candidate access, screen sharing, and connection reliability; give notice and offer a test. For remote work, useful criteria include guest access, recording, screen sharing, and possible single sign-on. Match the choice to the job, rather than treating every platform decision as the same decision. section 5.1.5 section 7.4.1
