While reading the book Agile Estimating and Planning by Mike Cohn, came across a chapter on Dozen guidelines for Agile estimating and planning. The book and guidelines reminded me of a road trip that myself and two friends undertook from Delhi to Leh and back, in 2011.
What follows is an account of what we planned to do and what we ended up doing actually.
What was planned
Trip Duration was 9 days. Plan was to travel from Delhi to Manali to Leh, via Keylong and Sarchu. Spend time in Leh, see Pangong Tso lake, visit khardung la , one of the highest motorable passes in the world and few monasteries around Leh. Return route was Leh-Kargil-Srinagar-Pathankot - Delhi. The attached map shows the route planned ( courtesy google maps)
Day 0 - Arrive in Delhi - Hire cab
Day 1 - drive via manali rohtang pass (rohtang means pile of corpses) and at Night - Rest in Keylong
Day 2 - Drive Past Sarchu and take rest in plains - if possible reach leh
Day 3 - See around Leh
Day 4 - See around Leh
Day 5 - See around Leh
Day 6 - See around Leh
Day 7 - Start return trip back to Delhi
Day 8 - Drive to Delhi
Day 9 - Reach Delhi and catch evening flight back home
What was considered in planning. Planning started as soon as we were forced to abort a similar trip in 2010
- Timing was key. Depending on snow fall, the Manali Leh Road opens anytime from May-June. It may also get closed in case of heavy snow fall. When open, priority is always given to Army Vehicles.
- If we took the trip too early, we risked not completing the trip due to snow blocked roads. If we did the trip in August, the snow capped mountains will have less snow and the view will not be that great.
- Be in good physical condition. The terrain and altitude can be demanding. And HAS was a readl threat and it meant that we had to exercise regularly.
- Experiences from an aborted trip in 2010 when we couldn't proceed beyond Keylong.
- Bad roads and unpredictable weather leading to traffic jams
- High altitude sickness (HAS): Altitude sickness is a serious health concern. If not attended to in time, it could turn out to be fatal. (HAS and preparation against it deserves a separate post)
- Time delays caused by stopping to Photograph on the way as accommodated.
What Actually Happened
Day 0 - Arrive in Delhi - Hire a cab - Start driving at early hours of day 1
|What caused the road block|
Day 2 - Traffic was still blocked at day 2 morning. We decided to come back to Manali and take rest. 2 of the 3 show signs of food poisoning.
Day 3 - Start at 3.30 Am to cross Rohtang pass. We manage to cross the blocked road. But our innova was gashed by a heavy vehicle that slipped. In the process, Innova loses LHS rear view mirror and suffers damage. The LHS front door couldn't be opened from outside. Crossing the breached road gave us some jittery moments as a mistake in driving the vehicle could lead to a disconnected clutch. Due to the skills of the person who was driving, we crossed this place safely. We stopped for lunch along the way and decided to drive as long as the lights would allow and ended up staying in Sarchu for the night .

Day 4 - Morning while trying to have breakfast (we didn't feel like eating anything), checked at the tent for the nearest army hospital. We visited the hospital that was a few thousand metres away. The doctor checked us and two of the three put on oxygen. Fortunately for us, the oxygen levels improved and with some suggestion and advice along with free medication, doctor says the team is fit to drive. Tells us that we will be okay once we reach Leh and asks us to consult a doctor there.
|Sarchu - Road condition|
|Day 8: Drass - it was freezing and we stopped over for a cup of tea|
Day 6 - See around Leh - Visited Thiksey and Hemis Monasteries.
Day 7 - Start drive back to Delhi. Visit Alchi Monastery on the way. Overnight stop at Kargil
Day 8 - Early morning start from Kargil. Route back was Kargil- Drass - Srinagar-Pathankot and Delhi.
Day 9 - Almost non stop drive for 36 hours - reach Delhi just in time to catch evening flight back home
- It was a physically demanding and tiring journey, but mentally very fulfilling. In physically demanding trips, if people are not set in the right frame of mind, it will only make the trip more difficult and intolerable...So the team composition becomes very important - Lesson learned from 2010 trip
- The roads demanded complete focus on driving and drivers always had to be at their best.
- Don't skip food at any point. Whenever wherever possible, have a heavy breakfast. Fat in the form of butter is fine as the body needs it a lot.
- Don't stay at Sarchu overnight - The altitude makes things bad and complicates it for people who are not very fit.
- Keep drinking lot of water when in Leh. Water mixed with electrol is better. Dehydration is a serious problem
- Our plan was too aggressive and we should plan for a 15 day trip and not a 9 day trip to cover in detail all that we planned.
- Don't drive when tired and avoid night driving as much as possible
- The picturesque views along the way were worth the trip and more. What is captured through photos is only miniscule part of it and doesn't do justice to the place.
- When body suffers from low haemoglobin levels, it impairs the ability to absorb oxygen. While this is okay at plains, it is not at all okay at higher altitudes. One of the ways to improve haemoglobin levels is regular exercise.
- The Army hospitals are equipped with the best of infrastructure and open only when the roads are open ( may to september/october).
- The roads are maintained by Border Road Organization (BRO) who man the roads round the clock. We owe the successful completion of the trip to the Indian Army and BRO.
I think we followed certain Guidelines for Planning, when i look back at the trip now after two years.
- Like Agile Projects, we were time boxed. We had set out to achieve certain objectives ( drive by road from Delhi to Leh and back to Delhi) and to see places in and around Leh, but were constrained by the fact that we had 9 days to achieve this objective.
- The whole group understood the objectives of the trip, the perils involved and was involved in decision making, though primary responsibility for certain activities fell with one person.
- Planning happened at different levels ; at the highest level it was the road trip and it was gradually broken down with the lowest being the immediate destination on hand.
- The distance to be travelled and the total time needed were never mixed.
- Uncertainty in our plan was accepted and expressed using range. time taken to reach a place was always expressed x hours plus or minus y hours and never x hours. depending on the actual time made, subsequent targets were accordingly modified.
- Planning happened on the ground and kept changing often.
- Lessons learnt on the ground were continuously incorporated into subsequent planning.
- What could be achieved in a day was kept realistic and not over ambitious - other than the drive to reach delhi because we had to be at work next day .
- What we could see/accomplish was continuously prioritized - we dropped Pangong Tso and Khardungla as the group wasn't physically upto the demands and were worried about HAS.
- Planning happened based on actual numbers and also on our experience from 2010 trip.
- We did leave some slack in the planning, but that slack was consumed by the delay in crossing Rohtang pass
