Pros
WD places a premium on tactical execution and the company is generally very good at this. Programs are monitored very closely and usually delivered in a very timely manner. Compensation is usually very competitive making it easier for managers to attract and retain good talent. Personnel are generally very adept at overcoming obstacles. There is a high degree of solidarity between team members when facing challenges.
Cons
The company struggles to produce truly innovative products and features, typically playing it safe with "me too" features. The culture also can be highly adversarial which typically has a very stifling effect on innovation because innovation involves becoming good at failing gracefully and learning from and building on those failures. Finger pointing kills this necessary innovation feedback loop. Innovation also requires a solid process pipeline from ideation all the way through to customer delivery and support. There is little institutional knowledge and support of what this is actually supposed to look like.
