I suspect that you, like most others, are asking for quick ways to be able to estimate times and schedules accurately <i>without doing any work.</i><p>That won&#x27;t happen.<p>Here are a few previous discussions:<p><a href="https:&#x2F;&#x2F;hn.algolia.com&#x2F;?query=software%20estimation&amp;sort=byDate&amp;dateRange=all&amp;type=story&amp;storyText=true&amp;prefix&amp;page=0" rel="nofollow">https:&#x2F;&#x2F;hn.algolia.com&#x2F;?query=software%20estimation&amp;sort=byD...</a><p>If you&#x27;re serious, start by reading some of those articles, especially the ones that HN contributors have said are valuable, useful, accurate, or otherwise &quot;good.&quot;<p>Then summarise what you&#x27;ve done, and come back to let us know.  People here will then add their experience and expertise.<p>Don&#x27;t expect a quick fix - there isn&#x27;t one.  Accurate estimation can be done, but it&#x27;s hard work.
