And it's not just about technology. In practice, this decision involves&nbsp;<strong>Execution capability, total cost, risk, and maintenance over time<\/strong>.&nbsp;<\/p>\n\n\n\n<p>But why does this question arise?&nbsp;<\/p>\n\n\n\n<p>The trigger is usually predictable, management processes become more structured and complex. The company begins to monitor goals, results, initiatives, indicators, routines, and developments with greater rigor. The spreadsheet, which was agile at the beginning, becomes an operational risk with manual errors, conflicting versions, lack of real-time updates, and low traceability.&nbsp;<\/p>\n\n\n\n<p>From there, many organizations follow two paths:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Build an internal tool with the IT team<\/strong>.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Acquire a SaaS solution that is already established in the market<\/strong>.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<p>The \u201ccorrect\u201d answer always depends on the context. But there are objective criteria that help to see the real implications of each choice.&nbsp;<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>\u201cThe choice between an on-premise system and SaaS is not about technology, it's about how the company sustains its operation over time.\u201d<\/p>\n<\/blockquote>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-7e13b43b4b7e9b09e511e0baacefe0aa\" id=\"h-o-que-significa-desenvolver-internamente-na-pratica\" style=\"color:#2faf10;font-size:25px\"><mark style=\"background-color:rgba(0, 0, 0, 0);color:#00d084\" class=\"has-inline-color\"><strong><strong>Developing in-house means creating a product, service, or software within your own company, using your own employees and resources, rather than hiring an external company or buying a ready-made solution.<\/strong><\/strong><\/mark><\/h2>\n\n\n\n<p><\/p>\n\n\n\n<p>Many people still imagine development as \u201cgetting a programmer to work.\u201d However, it's much more than that.
