【案例2】背景材料：某桥梁工程由A公司承包，其中的桩基施工分包给B公司，为了抢工期，在总进度计划尚未编成的情况下，先行与B公司签订了分包合同。B公司的项目部按分包项目的工程量、施工方案及计划投入的工、料、机，编制了桩基施工进度计划。A公司事后发现B公司的这个进度计划与A公司刚编完的总进度计划不协调，会严重拖后整个工程的总工期，要求B公司重编。问题：1．为什么B公司的分包工程进度计划会严重拖后整个工程的总工期？A公司和B公司做法各有什么对错？2．应该如何纠正？
Passage 5 Can the Internet help patients jump the line at the doctor’s office The Silicon Valley Employers Forum, a sophisticated group of technology companies, is launching a pilot program to test online "virtual visits" between doctors at three big local medical groups and about 6,000 employees and their families. The six employers taking part in the Silicon Valley initiative, including heavy hitters such as Oracle and Cisco Systems, hope that online visits will mean employees won’t have to skip work to tend to minor ailments or to follow up on chronic conditions. "With our long commutes and traffic, driving 40 miles to your doctor in your hometown can be a big chunk of time," says Cindy Conway, benefits director at Cadence Design Systems, one of the participating companies. Doctors aren’t clamoring to chat with patients online for free; they spend enough unpaid time on the phone. Only 1 in 5 has ever E-mailed a patient, and just 9 percent are interested in doing so, according to the research firm Cyber Dialogue. "We are not stupid," says Stifling Somers, executive director of the Silicon Valley employers group. "Doctors getting paid is a critical piece in getting this to work." In the pilot program, physicians will get $ 20 per online consultation, about what they get for a simple office visit. Doctors also fear they’ll be swamped by rambling E-mails that tell everything but what’s needed to make a diagnosis. So the new program will use technology supplied by Healinx, an Alameda, Calif-based start-up. Healinx’ s "Smart Symptom Wizard" questions patients and. turns answers into a succinct message. The company has online dialogues for 60 common conditions. The doctor can then diagnose the problem and outline a treatment plan, which could include E-mailing a prescription or a face-to-face visit. Can E-mail replace the doctor’s office Many conditions, such as persistent cough, require stethoscope to discover what’s wrong and to avoid a malpractice suit. Even Larry Bonham, head of one of the doctor’s groups in the pilot, believes the virtual doctor’s visits offer a "very narrow" sliver of service between phone calls to an advice nurse and a visit to the clinic. The pilot program, set to end in nine months, also hopes to determine whether online visits will boost worker productivity enough to offset the cost of the service. So far, the Internet’s record in the health field has been underwhelming. The experiment is "a huge roll of the dice for Healing", notes Michael Barrett, an analyst at Internet consulting firm Forester Research. If the "Web visits" succeed, expect some HMOs (Health Maintenance Organizations) to pay for online visits. If doctors, employers, and patients aren’t satisfied, figure on one more E-health start-up to stand down. According to Paragraph 2, doctors are ______.
