Your role on SENTINEL got approved on a Tuesday afternoon. You open the system record and find a few hundred controls, thirty-one open POA&M items, an authorization termination date nine months out, and a previous ISSO who left behind a shared drive folder named FINAL_v3_USE_THIS and no notes. Everything in eMASS looks clickable. Nothing tells you what to click first. This is the thirty-day sequence I use when I inherit a package. It exists because the first time, I started editing on day two and spent a month undoing it.

What thirty days can fix, and what they cannot

Thirty days is enough to know exactly what you own, stop the package from getting worse, repair the handful of things that would get it bounced tomorrow, and set up a rhythm that keeps it healthy. That is the whole list.

Thirty days is not enough to close thirty-one POA&M items, rewrite every weak implementation statement, recover two years of evidence nobody collected, or move a system from a dead ATO to a new one. If your ATD is sixty days out instead of nine months, this plan compresses, but the order does not change.

The package you inherited is a record of someone else’s decisions, and you do not understand them yet. A control marked compliant with no artifact might be inherited from a provider whose package you have not found. A POA&M item with a strange milestone might be the one the validator personally asked for. Fix before you understand and you will break things that were quietly holding the ATO together. eMASS will let you. It has never once asked me if I was sure.

Week 1: Read, do not edit

Your only edit this week is confirming your own role. Everything else is reading. Here is what I pull, in order.

• Your role and what it can touch. Confirm which role you were granted and what it can change. The eMASS user roles and permissions breakdown covers why the same role name can differ between component instances.
• The system record header. System name and acronym, system type, categorization (confidentiality, integrity, availability), current RMF step, authorization status, and the ATD. Write the ATD on something physical. It decides how aggressive the rest of this plan has to be.
• The control count baseline. Total controls, and the split between compliant, non-compliant, and not applicable. Export it with today’s date. In week 4 you will need to prove the package moved.
• Open POA&M items. Count them. Note the oldest scheduled completion date, how many are already past their date, how many have no milestones at all, and how many have a resource estimate of zero. Those four numbers tell you more than any handover email.
• What evidence is attached, and where. Open the artifact list and note each file, which controls it is mapped to, and the date inside the document itself (not the upload date).
• Who is in the approval chain. Find out whether your package moves through a PAC, a CAC, or both, and who sits in each seat. PAC versus CAC approval chains explains the difference. Your package goes to specific people with queues, not to “the AO.”

Find the humans

By Friday you should have talked to the ISSM, the system administrator who runs scans, the program manager who owns the money, and whoever at the validation shop last touched the package. Ask each one the same question: what about this package worries you? At least one of them has been waiting months for someone to ask.

The notebook

Keep one running document outside eMASS from day one. Every number, name, and “the ISSM said this is fine” goes in it. In week 3 it becomes your change log, and later the handover notes you wish you had received.

Week 2: The inventory and the gaps

Now you compare the package to the system it claims to describe. This week produces a ranked gap list, not fixes.

Hardware and software list versus reality

Pull the current asset inventory from your scanner or asset tool, sit with the system administrator, and walk the eMASS hardware and software list line by line. Decommissioned servers still listed, new virtual machines missing, software three versions behind: mark every mismatch, and do not fix it yet.

Boundary diagram versus reality

Lay the diagram next to the inventory and the network team’s current drawing. Look for interconnections that exist on the wire but not on paper, cloud components that were added after the last authorization, and anything in the diagram that was unplugged a year ago. A boundary diagram that lies is the fastest way I know to turn a routine review into a hostile one.

Controls with no evidence

Go control by control, or pull the control status export and sort by artifact count. Every control marked compliant with zero artifacts mapped to it goes on the gap list. These are your exposure. The previous ISSO may have tested them perfectly, but a package that cannot prove something is treated as if it is not true.

Stale artifacts

Compare every artifact’s internal date against the monitoring frequency recorded for its control. Vulnerability scans older than your component’s required window, a policy signed by a commander who left two rotations ago, a training roster from a prior fiscal year, an account review with no reviewer signature: flag all of it.

Inheritance that no longer holds

Inherited controls are the ones that break silently. The provider’s package may have been reauthorized with a smaller scope, the hosting may have moved, or the common control provider may have decommissioned entirely while your package still says “inherited.” Confirm each provider is still authorized and still covers what you think it covers. How to inherit controls in eMASS covers the mechanics of checking.

End the week by sorting the gap list into three piles: blocks the package, looks bad to a validator, and cosmetic. Week 3 only touches the first pile.

Week 3: Fix what blocks the package, and start the change log

Now you edit, in a narrow order, and you write down every edit. Here is the order I use.

1. POA&M dates and milestones. Every item past its scheduled completion date gets a realistic new date you have confirmed with the person doing the work, at least one milestone, and a comment explaining the slip. Do not close anything you cannot prove was fixed. An overdue POA&M item is a known problem; a closed one with no evidence is a false statement in a federal record.
2. Stale scans. Get the system administrator to run a current vulnerability scan and a current STIG check on the in-scope assets, then attach the results to the controls that depend on them.
3. The three weakest implementation statements. Three, not thirty. Pick the controls a validator reads first: in my experience that is account management, configuration settings, and flaw remediation. Rewrite each one to say who does the thing, what tool or process does it, how often, and which attached artifact proves it. If a statement reads “the system complies with this control,” it is one of your three.
4. Missing artifacts on compliant controls. For each control on the blocks-the-package pile, either attach real evidence or change the status to reflect that you cannot yet prove it and open a POA&M item. Honest non-compliant beats fictional compliant every time I have watched it play out.

The change log

Starting now, every edit gets a line in your notebook: date, control or POA&M item, what changed, why, and who asked for it or agreed to it. eMASS keeps history, but it records that a status changed on a date. It does not record that the status changed at 4:55 on a Friday because the ISSM said “just make it green before the brief.” Your log is where that reasoning survives, and it is what you hand the validator who asks why forty things moved in a month.

Week 4: Build the rhythm

The fixes from week 3 decay if nothing holds them in place. Week 4 is about the structure that keeps the package from drifting back.

• The SLCM calendar. Take the monitoring frequency recorded for each control and put every recurring task on an actual calendar with a named owner. The SLCM fields and monitoring frequency post covers what those fields need to say for the calendar to be defensible.
• The monthly evidence refresh. Pick one day each month. On that day the scan, the account review, and the audit log review get collected and attached, and the change log gets updated.
• The ISSM check-in. Thirty minutes, standing, with the same three items every time: what changed in the package, what is blocked and by whom, and what needs the ISSM’s signature or escalation. Bring the change log.
• The first package report to the AO’s staff. One page. Control status now versus your week 1 baseline, POA&M count and oldest open item, ATD and days remaining, inheritance status, and your top three risks in plain language. Send it through the ISSM even if nobody asked. They remember the ISSO who told them the truth before they had to go looking for it.

What not to do in the first thirty days

Every one of these looks like progress and every one of them costs you months.

• Bulk status changes. Flipping forty controls to compliant in one afternoon leaves a history trail that every validator reads the same way: the new ISSO did not test anything. One control at a time, evidence first.
• Deleting artifacts. Even stale ones. Attach the replacement, note that the old file is superseded, and leave it. A deleted artifact looks like something was hidden, and you cannot prove otherwise once it is gone.
• Resubmitting the package “to see what happens.” It lands in a real person’s queue, consumes a review slot, and the rejection comments stay in the record for the next reviewer. I have watched a package sit four months over one narrative that could have been fixed in a day, because it was submitted before anyone read it.
• Rewriting the system description in week 1. You do not know the system yet. Wait until the boundary and inventory walks in week 2 are done.
• Promising a date you have not checked. The ISSM will ask when the package will be ready. Your answer in week 1 is “after I finish reading it.” Any other answer is a POA&M item on yourself.
• Closing POA&M items because the date passed. The scheduled completion date is a promise, not a timer. Passing it changes nothing about whether the weakness exists.

At the end of thirty days you will have an accurate picture of what you own, a package that is no longer actively getting worse, three statements a validator will not bounce, a change log, and a calendar that does the remembering for you. That is not a finished package, and anyone who says thirty days produces one has not inherited one. This is the sequence I wished someone had handed me the week I got my first inherited system. If you are building a package from nothing rather than inheriting one, the ATO Package Kit’s 54-page guide walks the full build from registration through submission, with the SSP template and statement library to go with it.
