PHASE 2 OF IMPLEMENTATIONS 
If you have ever been a part of a major system implementation, especially a multi-functional ERP level one, you have certainly heard of the dreaded 'Phase Two'. Functionality or modules beyond the core, customizations to improve the default process, additional reporting or interfaces…all have the hallmarks to get added to a white board parking lot, and then end up on the Phase Two list. 
Phase 2 Expectations Vs Reality
The Expectation: 
Phase 2 will kick off soon after Go-Live 
One Phase rolls right into the next Phase from a 'who' standpoint 
The items identified for future Phases are critical to long-term success and simply HAVE to be done 
The Reality: Going Live and staying live takes time, Phase 2 never gets attention or momentum 
The Phase 1 team goes back to their regular jobs, the budget is used up, and the supporting resources move on to the next gig 
The business gets running the new way, and the Phase 2 items don't feel as critical…so they don't get started 
Planning for Phase 2 
The reality BEYOND the realities above though is that there usually should be additional phases to an implementation. There are additional modules that just didn't fit the scope, there are automations or other tweaks that would greatly improve processes or controls, and frankly no project gets everything done quite right (or they would never end). In fact, most businesses could stand for a regular cycle of planning and executing of phases and upgrades. Assuming then at least this concept makes sense…read on! 
So here are some ideas that might help you achieve a successful Phase 2 (and beyond…): 
Planning 
Begin planning a REALISTIC time-frame for Phase 2 well before go-live 
Allow a buffer, even a few weeks, between the Go-Live and actual Phase 2 kickoff. But make sure it's a KNOWN buffer 
Use that time to re-evaluate those built up requests, re-prioritize against the LIVE situation instead of the 'implementation' situation (new pain points will always outweigh those the team 'thought' were coming) 
Don't wait until Go-Live is imminent, things get too crazy those last weeks. Instead, find time after final tests are complete. That 'slightly slower' time-frame when PMs are waiting on final migrations, report development and end user training 
Create a separate Project, with separate budget and resource allocations 
They are separate events, don't let budget issues in one project time-frame de-rail another one 
Users on an implementation often get burned out, so try and use different resources for a new perspective anywhere it makes sense to 
If you can keep the best external resources involved, they can help guide new team members as well 
Phase 1.1 
As items are defined as actually CRITICAL, set them into a Phase 1.1 
This Phase should start immediately after Go-Live, and get a very limited set of things taken care of 
Focus on key reports, important controls and known pain points. Those items that you might otherwise have even delayed Go-Live for 
The existing core team can be planned ahead of time to keep things going for this short phase 
This has NUMEROUS benefits, including: 
Shows post Go-Live progress is possible 
Helps both keep the implementation on track (instead of waiting for these things and causing a delay) AND takes the pressure off of Phase 2 because some key things are already done! 
Tracking and Managing Phase 2 
The process for keeping track of Phase 2 begins almost on day one of Phase 1, sometimes even before the kickoff. Modules that are not in the 'must have' core process flow are often scheduled for Phase 2 in sales contracts. Tracking and managing what's in future phases isn't complex, but it can make a big difference as to whether or not things actually get done. 
Phases vs Continuous Change 
The first decision to make. Will we have formal phases with Project Management and more structure or will we have a more free-flowing 'ongoing change' standard of proceeding 
Either way can work of course, but having more formal Phases allows for cleaner tracking of status, more cross-functional visibility, and establishes that cadence of change/breathe/change/breathe 
Tracking and managing during Phase 1 
Phase 2 lists can often become black holes, where To Do items can be consigned to neglect 
Keep the Phase 2 list on a steady schedule of review 
Normal PM meetings should always include at least some review and organization 
Move things forward to 1.1, remove them as not required, or push out into a 'future' Phase 
Keeping priorities in the right Phase can also make the objectives seem less daunting 
As part of Steering Committee or similar meeting, include Phase 2 summaries 
This will keep the information from being a surprise, demonstrates good planning, and allows those resource/budget discussions to flow naturally 
Formal tracking is essential 
What the item is, who requested it and why, and very importantly…what the impact is by NOT doing it in Phase 1 (this can easily slip minds…especially if there is turnover) 
Reviewing this then becomes easier as you (next up…) 
Without some depth in tracking, future phase items lose their context at the least, and lose all meaning in the worst 
What to include in a Phase 2 
Reports - Those reports everyone THINKS they need, but don't HAVE to have for Go-Live 
If it isn't in the ERP already, and isn't legal/statutory/senior management, it can probably wait anyway as there may not be enough good data to support it 
Controls - This could be security role updates, tweaking/tightening configurations, or custom items that 'make' rules (those not system-enforced) be followed 
Document Management - Enhancing how doc man is used into new areas 
Functionality/Modules - Core flows at most businesses can exist without some ERP components in place, but they are important to long-term adoption of the overall tool. Examples of modules that are often in Phase 2: 
Fixed Assets 
Quality (beyond basics) 
Project Management For those only using it for CAPEX or R&D tracking 
Human Capital Beyond the core requirements for employee creation 
CRM 
Maintenance 
Phase 2 can be almost as much work as the initial implementation, but it can go from essentially non-existent to a pleasant improvement and growth IF YOU PLAN. And it can be a positive experience if you incorporate good tracking and maybe a Phase 1.1. Now, let's move on to Phase 3 (I kid, I kid).
