I've got a couple ideas on how the French could do better at least at the beginning of the First World War:
1. The French strategy is focused on defending against a German thrust through Belgium.
While I think this is doable, there was a plan to defend against such a thing and the French gained an early draft of the Schlieffen plan in 1904, It would require that the French "Cult of the Offensive be discredited in some way. Also the French thought the early version of the Schlieffen plan was a ruse.
2. The French adopt modern uniforms earlier
Earlier adoption of more dull colors couldn't have hurt the French
3. Plan to use of reserve divisions in the same way the Germans used reserve divisions instead of planning to keep them behind the lines doing the clean up work. I think this would require some changes to the "Cult of the Offensive" as well.
4. The French offensives into Germany rout the defenders and are at the Rhine by Christmans, the British land on Germany's Northern Coast and are in Berlin by Boxing day and the war is over by New Years, Hooray. A man can dream can't he?
Anyway, if the French do adopt a plan of defending a German thrust through Belgium I see them being able to hold on to significantly more of North Eastern France than they did, thus greatly improving their position in later years. Also they wouldn't lose the men they did on their failed offensives into Germany. Meanwhile I see the Germans in a much worse position having lost more than they did in OTL as well as having gained less. Could this mean an earlier end to the War?
