Narrative:
Received initial clearance for the wevic one RNAV departure from slc ksino transition as filed. The wevic one states at top to maintain 16000 ft. I (first officer); read the filed clearance as wevic one departure ksino transition; X arrival into city; ksino transition. However; there is no ksino transition in FMC; so spent time questioning captain and clearance delivery about our route of flight and also took extra time inputting route into FMC. Inbound flight had been 5 mins late arriving; so already a little short on time. I gave a hurried clearance briefing; and failed to notice the 14000 ft mandatory altitude at zoobe; instead stating only that we were cleared to 16000 ft which was set in altitude window. Captain also failed to notice the restr at zoobe. While taxiing; ground control advised us to expect departure from runway 17; versus runway 16L as we planned. Cockpit jumpseat riders assisted with performance planning while I reprogrammed FMC for runway 17; again; taking our concentration away from the upcoming departure. Otherwise; taxi; takeoff; and departure were uneventful until ZLC advised us as we were passing approximately 14500 ft with greater than 4000 FPM climb; that there was a 14000 ft restr at zoobe. I responded to the call; but by the time we were able to level off; we had reached 16000 ft and center then cleared us to remain at 16000 ft; advised us of our deviation and gave us a number to call. Center also stated that this was the first day using this departure; and we were at least the 6TH aircraft to miss the zoobe restr. Obviously more attention to detail during the clearance briefing would have alleviated this problem. However; in my admittedly limited experience; this departure seems abnormal. Most other departures with a hard altitude lower than initial clearance altitude have the hard altitude very close (inside of 10 mi) to the airfield. Both the captain and I had noted the earlier restr at myrup and incorrectly assumed that there were no restrs further out that were a factor. I feel that changing the altitude section on the wevic one to read; 'maintain 14000' would completely alleviate this problem.

Title: B737 FLT CREW OVERLOOKED THE ALT RESTRICTION AT 'ZOOBE' ON THE WEVIC RNAV DEP; AND CLIMBED THROUGH THE MANDATORY 14000 FT.
Narrative: RECEIVED INITIAL CLRNC FOR THE WEVIC ONE RNAV DEP FROM SLC KSINO TRANSITION AS FILED. THE WEVIC ONE STATES AT TOP TO MAINTAIN 16000 FT. I (FO); READ THE FILED CLRNC AS WEVIC ONE DEP KSINO TRANSITION; X ARR INTO CITY; KSINO TRANSITION. HOWEVER; THERE IS NO KSINO TRANSITION IN FMC; SO SPENT TIME QUESTIONING CAPT AND CLRNC DELIVERY ABOUT OUR RTE OF FLT AND ALSO TOOK EXTRA TIME INPUTTING RTE INTO FMC. INBOUND FLT HAD BEEN 5 MINS LATE ARRIVING; SO ALREADY A LITTLE SHORT ON TIME. I GAVE A HURRIED CLRNC BRIEFING; AND FAILED TO NOTICE THE 14000 FT MANDATORY ALT AT ZOOBE; INSTEAD STATING ONLY THAT WE WERE CLRED TO 16000 FT WHICH WAS SET IN ALT WINDOW. CAPT ALSO FAILED TO NOTICE THE RESTR AT ZOOBE. WHILE TAXIING; GND CTL ADVISED US TO EXPECT DEP FROM RWY 17; VERSUS RWY 16L AS WE PLANNED. COCKPIT JUMPSEAT RIDERS ASSISTED WITH PERFORMANCE PLANNING WHILE I REPROGRAMMED FMC FOR RWY 17; AGAIN; TAKING OUR CONCENTRATION AWAY FROM THE UPCOMING DEP. OTHERWISE; TAXI; TKOF; AND DEP WERE UNEVENTFUL UNTIL ZLC ADVISED US AS WE WERE PASSING APPROX 14500 FT WITH GREATER THAN 4000 FPM CLB; THAT THERE WAS A 14000 FT RESTR AT ZOOBE. I RESPONDED TO THE CALL; BUT BY THE TIME WE WERE ABLE TO LEVEL OFF; WE HAD REACHED 16000 FT AND CTR THEN CLRED US TO REMAIN AT 16000 FT; ADVISED US OF OUR DEV AND GAVE US A NUMBER TO CALL. CTR ALSO STATED THAT THIS WAS THE FIRST DAY USING THIS DEP; AND WE WERE AT LEAST THE 6TH ACFT TO MISS THE ZOOBE RESTR. OBVIOUSLY MORE ATTN TO DETAIL DURING THE CLRNC BRIEFING WOULD HAVE ALLEVIATED THIS PROB. HOWEVER; IN MY ADMITTEDLY LIMITED EXPERIENCE; THIS DEP SEEMS ABNORMAL. MOST OTHER DEPS WITH A HARD ALT LOWER THAN INITIAL CLRNC ALT HAVE THE HARD ALT VERY CLOSE (INSIDE OF 10 MI) TO THE AIRFIELD. BOTH THE CAPT AND I HAD NOTED THE EARLIER RESTR AT MYRUP AND INCORRECTLY ASSUMED THAT THERE WERE NO RESTRS FURTHER OUT THAT WERE A FACTOR. I FEEL THAT CHANGING THE ALT SECTION ON THE WEVIC ONE TO READ; 'MAINTAIN 14000' WOULD COMPLETELY ALLEVIATE THIS PROB.
