Managing interim assignments: objectives, reporting and metrics
Get Interim SupportShort answer
An interim assignment is managed by the client company, not by the provider. Management works when there are three to five measurable objectives, a clear reporting line, a short weekly report and a review after two to four weeks. The most useful interim assignment KPIs are open caseload, turnaround time, deadline compliance, rework rate and handover status.
Short answer: An interim assignment is managed by the client company, not by the provider. Management works when there are three to five measurable objectives, a clear reporting line, a short weekly report and a review after two to four weeks. The most useful interim assignment KPIs are open caseload, turnaround time, deadline compliance, rework rate and handover status.
This guide is for general counsel, heads of legal and heads of compliance in Switzerland and Germany who bring in an interim professional or a project team. It shows how to set objectives, which metrics fit which assignment, what lean reporting looks like and what changes with the engagement model.
Who manages an interim assignment?
The company that deploys the professional manages the assignment. How far that management goes depends on the engagement model.
- Staff leasing (Swiss Personalverleih, German Arbeitnehmerüberlassung): the client holds the right to give professional instructions, and the professional is integrated into its organisation. You direct tasks, priorities and working methods as you would for a team member.
- Freelancing: the professional delivers independently within the agreed mandate. You steer through scope, deliverables and deadlines, not through day-to-day instructions.
- Project team with a team lead: the team lead allocates work within the team and reports to your internal management. In our KYC case study, the team lead of a taskforce of eight compliance officers reported to the client's internal compliance function.
Alpinum Solutions provides the professionals and is the contracting party; direction and responsibility for results stay with the client. This applies equally to interim legal and interim compliance work.
Setting objectives: from brief to measurable result
A good interim brief describes a result, not just a position. Set three to five objectives that can be checked at the end of the assignment.
- Vacancy or leave cover: "Requests from the business are answered within the agreed time; no deadline is missed; the handover to the successor is documented."
- Peak workload or backlog: "Open contract reviews fall to the agreed target level by the cut-off date."
- Project: "Gap analysis, action plan and revised policies are ready for the executive committee meeting."
- Remediation: "All files in the agreed scope are processed against the review template and documented so that auditors can follow them."
Record a baseline for every objective. Without one, you cannot show later what the assignment achieved. Our guide on briefing an interim lawyer shows how to describe task and result before the search starts.
Managing an interim assignment in six steps
These six steps work for assignments lasting from a few weeks to several months.
- Put the brief and objectives in writing: tasks, objectives, authority, workload and duration on one page. For freelancers, this is also the basis of the mandate.
- Capture the baseline: record caseload, turnaround time and open deadlines on day one, ideally from your existing ticketing or contract management system.
- Agree the reporting line and rhythm: one accountable person in the company, a short weekly report and a monthly conversation with management.
- Review after two to four weeks: do profile, workload and priorities fit? Are access rights and contacts in place? Scope and focus are still easy to adjust at this point.
- Adjust as you go: discuss deviations in the weekly report early, shift priorities deliberately and record decisions.
- Plan closure and handover: at least four weeks before the planned end, decide whether to extend, end or hand over, and measure the handover status.
What to do in the first days is covered in our onboarding checklist for day 1 to day 30.
Interim assignment KPIs: which metric for which purpose
A few metrics you already collect are worth more than a large dashboard. The table matches typical metrics to the reason for the assignment.
| Metric | What it shows | Best for | Data source |
|---|---|---|---|
| Open caseload | Whether a backlog is growing or shrinking | Peak workload, backlog, remediation | Ticketing, contract management or case system |
| Cases closed per week | Throughput of the assignment | Backlog, remediation, review | Case system, review log |
| Turnaround time | How long a request or review takes | Vacancy, leave cover, contract review | Date received and date closed |
| Deadline compliance | Share of matters completed on time | All assignments, especially regulatory work | Deadline calendar |
| Rework or escalation rate | Quality and independence | Review, contract work, teams | Spot checks, four-eyes review |
| Milestones achieved | Project progress against plan | Projects, system roll-outs | Project plan |
| Share of work sent to law firms | Whether the assignment replaces external spend | Vacancy, leave cover | Law firm invoices, matter list |
| Handover status | Whether knowledge stays in the team | All assignments, before the end | Handover list, documentation |
Always measure volume and quality together. High throughput with many follow-up questions does not take pressure off the team.
Reporting: format and rhythm
Half a page per week is enough for most assignments. The weekly report should cover five points:
- Done: the main results of the week, with a metric where useful.
- Open: matters in progress with their deadlines.
- Risks: deadlines at risk, missing information, capacity constraints.
- Decisions needed: questions the company must settle.
- Next week: priorities.
In staff leasing, the report is part of normal team management. In freelancing, it documents the status of the mandate. In teams, the team lead consolidates the reports. A short monthly conversation with management about objectives, metrics and further needs is worthwhile.
Roles and capacity: who does what during the assignment
Clear roles save more time than any reporting tool.
- Sponsor in the company: general counsel, head of legal or head of compliance; sets objectives and decides on extension or closure.
- Day-to-day contact: answers questions, approves legal decisions and runs spot checks.
- Interim professional: does the work, reports weekly and flags risks early. Levels range from junior (0–2 years' experience) through experienced (3–6 years) to senior (7+ years).
- Team lead (for teams): allocates work, keeps results consistent and reports to internal management.
- Alpinum Solutions: provides professionals through staff leasing or freelancing, part-time or full-time (20–100%), and agrees workload, extensions and transitions with you.
Switzerland and Germany: what differs
Objectives, metrics and reporting work the same way in both countries. The legal framework for directing the work differs.
| Topic | Switzerland | Germany |
|---|---|---|
| Term | Personalverleih or staff leasing; the client is the Einsatzbetrieb | Arbeitnehmerüberlassung (temporary agency work); the client is the Entleiher |
| Instructions in staff leasing | The agency transfers essential authority to give instructions to the client (Art. 26(1) AVV) | The professional is integrated into the client's organisation and follows its instructions (section 1(1) sentence 2 AÜG) |
| Employer | The staffing agency (Art. 12(1) AVG) | The agency (section 1(1) sentence 3 AÜG) |
| Duration | The leasing contract states the assignment period or the notice period (Art. 22(1) AVG) | Maximum of 18 consecutive months per professional and client (section 1(1b) AÜG) |
| Freelancing | The AHV compensation office assesses self-employed status case by case, based on the actual circumstances | Being bound by instructions and integrated points to employment (section 7(1) SGB IV) |
| Alpinum contracting entity | Alpinum Solutions AG | Alpinum Solutions GmbH (DE) |
In practice: in staff leasing you may and should give professional direction. In freelancing you steer through results and deadlines; managing freelancers like your own staff risks covert temporary agency work in Germany.
Limits and risks
- The wrong metric: measuring volume alone rewards speed over care. Always pair throughput with a quality metric.
- Freelancers managed like employees: day-to-day instructions and full integration fit staff leasing, not freelancing. Choose the model that matches the direction you need.
- No baseline: without a starting value, the impact of the assignment remains an opinion.
- Responsibility: your team signs off legal decisions. Alpinum is not a law firm and does not provide legal advice.
- Personal data in reports: report on matters and results, and do not collect more performance data on individuals than you need to manage the work.
Frequently asked questions about managing interim assignments
Which KPIs suit an interim assignment?
For peak workloads and backlogs, use open caseload and cases closed per week; for vacancies and leave cover, turnaround time and deadline compliance; for projects, milestones achieved. In every assignment, add a quality metric such as the rework rate and measure the handover status before the end. Three to five metrics are enough.
How often should an interim professional report?
A short weekly report covering what is done, what is open, risks, decisions needed and next priorities is enough for most assignments. Add a monthly conversation with management about objectives and metrics. With critical deadlines or large teams, a shorter rhythm can help, such as a brief daily check-in during the busiest phase.
When should the first review take place?
After two to four weeks. By then it is clear whether profile, workload and priorities match the need and whether access rights, contacts and templates work. Adjustments are easier at this stage than later. Record the outcome in writing and update objectives and metrics where needed.
Can I manage a freelancer the same way as a professional in staff leasing?
No. A freelancer works independently within the agreed mandate; you steer through scope, deliverables and deadlines. In Germany, day-to-day instructions and full integration point to employment (section 7(1) SGB IV). If you need that level of direction, staff leasing is the right model.
What belongs in the closure of an interim assignment?
A handover list with open matters, deadlines and file locations, a comparison of results against the baseline, and removal of access rights. Decide at least four weeks before the end whether to extend, end or hand over. A move into your team (temp-to-perm) is possible; the terms are agreed in advance.
