I am completing a new wiring project in which the cables are running directly from the wall jacks to a switch (team decided against using patch panels), my only question is should that connection be a crossover cable. I plan on using straight wire patch cables?
 
No. A patch panel is just makes everything easier. As long as you term both sides the same way, it should work. Unless I am SERIOUSLY mistaken.

Did they consider performance issues and cleanliness? I don't think they will be happy with it in the very near future. my two shiny coppers. Good luck.

No crosss over cabling should be required for the cables going directly to the workstations from the switch.

You may need a cross over cable,depending upon the switch used, to connect it to other switches.

Doing it the way you are is not suggested as the cables will have to be custom lenghts and the RJ 45 connectors at the switch end will have to be installed by hand. This may or may not lead to 'cross talk' and other issues as far as the cabling meeting compliance when testing for network certification.

Good Luck,

You will be thanking yourself later for going ahead and installing a patch panel
 
As a rule, you don't use solid wire as a termination point. You need a patch panel, with stranded wire patch cords. Identification is so much easier with a patch panel, than a Sharpie mark or electrical desi tape.

If you will be crimping plugs onto the wire directly and supposing you are using the proper solid cable, you should buy the proper types of plugs. They look the same but have different mechanics to grab onto the solid core.
 
Akwong hit my main concern. Crimping the plugs on the cables. This is really going to hurt down the line. Besides patch panels being cleaner, you now have something that is going to give you trouble. I am not saying "Never" crimp plugs on, but not for the whole install. Punching these down on a patch panel gives you something that will give you not only a better, trouble free connection. But also a hell of a lot easier connection to troubleshoot should you have problems down the road.

Thanks everyone. I will try to convince them to use the patch panels in the closet, it sounds like that will make it much easier in the future. I assume I will still use straight through cabling this way as well, going from patch panel to wall plate.
 
It will cost a little bit more to add the patch panels now but save so much more over the life of your cabling.

Just add the same wiring scheme on both ends and you done. Use factory made patch cables (as close to the actual length) as you can in wire management and you will (or whoever does your repairs) will be set for years to come.

To me and I'm sure everyone else here would agree, I'd prefer to fork out a few extra bucks now on a patch panel, that could potentially save me hours of troubleshooting and possible re-cabling in the future.
It costs more to cut corners than it does to do it the right way. As mentioned terminate both ends using the same scheme: if your jacks are punched using the B scheme, use the B scheme on the patch panel. Both sides are real easy to follow.
