I got my first positive pregnancy test 9/9 and got 3 hcg betas that all rose beautifully. i thought i was around 7w4d today for my scan but baby was measuring 6w2d with a heart beat of 95. the MFM tech said she has seen it go both ways. could I be that off in my ovulation date? should i be preparing for this to be nonviable? TIA

Dependencies trip people up more than almost anything else on a Gantt chart, so here's a quick cheat sheet:

Finish-to-start (FS): B can't start until A finishes. Pour the foundation, then frame the walls. This is the most common type, and if A slips, B slips too.

Start-to-start (SS): B can't start until A starts. They don't have to start together. Once editing starts, proofreading can start on the finished chapters.

Finish-to-finish (FF): B can't finish until A finishes. Testing can't wrap up until development wraps up, even though they overlap.

Start-to-finish (SF): B can't finish until A starts. It's rare. Think shift handoffs: the night guard can't leave until the day guard arrives.

Lead vs. lag:

• Lead: the successor gets a head start because the predecessor finished early. Planned for 5 days, done in 3, so a 2-day lead.
• Lag: the delay passed down the line when the predecessor runs over. Planned for 7 days, took 10, so a 3-day lag.

People often assume task A is always the predecessor. In a start-to-finish dependency, A is actually the successor.

Which dependency type causes your team the most trouble?

Disclosure: I work at ProjectManager.com. We turned this and a lot more (building a Gantt chart step by step, WBS + Gantt, Gantt vs. PERT) into a free ebook. Happy to drop the link in the comments if it's useful.

Hi there, I'm newer to the field of project management and really trying to hone my skills before applying to jobs. I have a couple of certifications so far but I'm still lacking some confidence. I've found ProjectManager to have some great resources and educational videos, especially on YouTube, but learning things online doesn't always translate to real-world success.

Wondering if anyone else is in a similar boat and can point me in the right direction? I'm trying to join LinkedIn groups, read articles, play around with software, etc. any specific recommendations to help? it's a competitive industry and I want to invest my time wisely. thanks!
